A look at the load rating will give a good indication whether a particular size is LT or not.

Most appear to be LT

Another update on the Maxxis.

Just drove up to Brissy today from Sydney.

Tyres were smooth and quiet even when I had the window open I didn't notice any noise.

So it seems that 90klm/por and up they are great for noise, 60-80klm they're a little annoying at times.

First leg of the journey returned 9.1L/per 100klm :)

Hi, Attached is as promised back in May.
Excellent report thanks. This is the tyre I'm recommending to Dad to replace the Hankooks, which have travelled well on bitumen and graded dirt but seem weak in the sidewall. I have pasted your report from the attachment below just for convenience of reading.

Maxxis 980 255/55/R19 Report by "FM231"

Back in May I posted that I had purchased a set of Maxis 980 19inch tyres for my D4 for an upcoming caravan trip around the country and on return would report my comments on the tyres performance. This then is the follow up.

The trip was planned to also include dirt/rough roads and beach driving. My decision to select this tyre was based on them being an AT and equivalent 10Ply rating and a load spec. of 1215kg @ 80PSI, the tread pattern looked ok, they looked solid in the sidewall and the price was right.

Prior to this I would like to say that I have had a FWD (110 County V8, D1, Ford F250 and now the D4) continuously for 30 years and say 500,000 kilometres. During this period I have travelled many of the iconic tracks initially tenting, then with a slide on camper and more recently with a caravan (age catches up).

Some of the detail I will include in this post may raise comment from readers and that is their right however I am not prepared to defend anything I include, but I am prepared to evaluate others ideas.

I had the Maxxis fitted and a full wheel alignment carried out about two weeks before we left on our trip, my initial reaction on driving the 30 kilometres home was one of "I am now in a real FWD, there is tyre noise", this was at normal road pressures. The noise was not near the volume as mud tyres but they reminded me of the old BF Goodrich ATs that I had on my 110 County, I do find the Maxxis are noisy at all pressures I ran them at, I find them a little less noisy at highway speeds but not much but I am comfortable with the noise level. I have no explanation why others say they are not noisy

Prior to my trip I weighed the vehicle with a full tank of fuel and including myself, this equalled 2700 kilos, I then loaded my self made draw system and 40 ltr fridge in the rear compartment with all their contents plus an extra spare tyre (only tyre) on the roof rack and repeated the weighing exercise finding now 2930 kilos. Note, this puts the majority of the load behind the rear wheels. The only addition of significance after weighing was my wife at approx 55 kilos.

My caravan weighed in at a total 2700 kilos and had a ball weight was 245 kilos.

Our trip went for almost three months, high frequencies of rain; strong winds and cold temperatures down the WA coast had us home earlier than planned.

Travelling with the caravan I experimented with tyre pressures and finalised for the bitumen front tyres set at 45psi cold and the rears at 55psi cold, with the front tyres my range of experiment was between 35 - 55psi and the rear tyres between 45 - 65psi. At the selected settings I did find that the rear tyres were a little warmer to the touch than the fronts, which probably indicates the sidewalls were working a bit more. On the dirt corrugations I lowered the fronts to 30psi and the rear to 40psi., speed for the dirt roads never exceeding 65ks/hr. The decision to select the above pressures when towing the caravan was based on the highly technical evaluation of that it "felt right".

On corrugations without the caravan I ran the fronts at 30psi and the backs at 34 psi. and restricted speed to 80ks. On the beach I ran them at 16-18 psi (refer GOE handbook).

In total we travelled 17700klms, averaged 15.65 litres/100ks at an average fuel cost of $1.295 per litre of diesel.

When new the tyre tread depth was near as I could measure 10.2mm, when measured on return home the range over the four tyres was between 7.8 - 8.2 mm tread depth (my measuring to one decimal place on a tyre could be successfully questioned). Tyre were swapped front to back etc. after 12000ks, all four tyres visually look to be worn evenly across the tread, the sidewalls do not show any scuffing or damage. I think the noise level is similar now to before the trip.

We experienced high wind, torrential rain and some thick mud roads and never even including some emergency evasive "aw ...t" moments both with and without the caravan on did the tyres cause any concern, on one occasion they felt like they were actually tearing up the bitumen.

In summary I am very happy with these tyres and yes mine have some noise, they look to wear well, I feel safe with them, are not as expensive as some others and performed excellent on all the surfaces I travelled.

[ozscott]

They are excellent tyres irrespective of cost. It happens that they are also well priced. You need to have confidence in your tyres. I have always been utterly confident in the sets I have had on 2 vehicles. Cheers

Tyre update.

I have about 7k klm on them now.

This weekend I had a good test for them, with extreme wet conditions on my farm.

Dirt roads in, they performed excellent, they gripped really well, where the Defender would slip in the dry I pushed these even harder in the wet and they held on.

On my property drove up to about 1klm above sea level no problem, didn't bother dropping pressure (42psi) and I was impressed.

I had a little slip just towards the top but that was because I had no throttle I was just crawling up, so I backed down a little started off slow and built up a slight momentum through that sticky spot.

My mates Ford Ranger with Diff Lock, Cooper ST Maxx and 6k Fox Suspension didn't get past that point so easily.

Can't let the tyres take all the credit, the Discovery's 4wd system is amazing.

Overall so far I'm impressed with the Maxxis's performance :D.

New update with regret.

Just found this today. Obviously happened at the farm on the weekend.

114521

Which totally ****es me off as this should not have happened on bulldozed tracks.

There are loose rocks everywhere, and the spot where I got slightly stuck is a little rocky but not enough that this should happen :(

I'm really disappointed that driving on a track and nothing hardcore has ended with a slash in sidewall. In over 20 years I have never had sidewall damage and I have done some stuff where I thought the tyres would not survive and they came out unscathed. Always in the past been on 16-17" rims running 32" tyres.

I also have some chips out of my front left rim (factory 19"), I'm assuming this happened in the sticky spot. It probably lifted some rocks out of the track when it lost traction and spun.

This just goes to show that the low profile tyres are extremely vulnerable and susceptible to damage along with the rim. :(

Cheers, Babs :D Sent from my iPhone using Forum Runner

[ozscott]

Sorry to hear that Babs. Thanks for telling it how it is. Too many times people who say that low profile tyres are as good as 16 inch tyres are cried down on the D3/4 and RR forums. Low profile tyres and Rims are more prone to Offroad damage. Just because some have run 19's without damage does not change what should be an easy to understand fact. Stick another tyre on mate and keep up the good driving and having fun in a very nice vehicle.

Cheers and thanks.

[Tombie]

If its not down to the cord.. don't worry about it... just move it to the rear axle.

You can't blame profile on that cut though, that's a slice so something sharp has come up and done that... I've had the same on almost every tyre on every 4wd I've ever owned...

[Tombie]

What more likely assisted... 42psi [emoji6]

[Tombie]

This has been a really big point of discussion on trips.

Babs, one of the first things you noticed - how effortlessly the D4 eats tracks... easy to get enthusiastic and go harder than you'd ever try in a Solid axle like a Defender - the Defender let's you know when to tone it down a bit [emoji4]

Up my way we have a very nice unsealed road or 2... when driving in my 110 anything over 90km/h on the loose sweeping road would immediately indicate slowing down was preferable. In the D4 I have many a time done the same track at well over state limits and never felt the vehicle feel unsettled.

The stresses this is imposing on tyres and suspension is incredible and the vehicle masks it so well you tend to lose yourself in the moment.

If driven with the same respect as a Defender owner would travel the same stretch of track you'd be going 40% slower.

Bytemark and myself on the trip a few years back spoke at length on the topic - him on 19s and me on 18s.

When we travelled with the group (Alien etc) doing a good pace it was easy to pick gibbers etc and avoid any problems. Once we fell back (photo stops etc) and then paced up to catch the group the need to be vigilant was increased as we were going much harder and throwing rock around.

The biggest killer, flicking up a rock with the front tyre exposing the sharp edge and then running over it with the rear tyre..

[scomac]

Just bad luck mate, that could happen with any tyre/profile/size. But high pressures don't help!
Cheers
Scott.

Has anyone discussed a comparison between the Yoko Geolander AT and the Maxxi? I'm very impressed with what I have read so far on the Geolander. But I have no real world experience with them and dont know anyone that has.


When mine are due (18'' Freelander 2 ) I will be probably tossing between these two.

I can't see how their sidewall rubber would be softer after going to all that trouble to make them LT and hard wearing.

I have been driving those track and worse in that region for years on Coopers and BFG and never ever had tyre damage.

I had a mate a couple of years ago slice a sidewall on standard Hilux tyres and put it down to a freak incident but not now, I'm now convinced the Coopers and BFG are a lot tougher tyre in the sidewall.

For the driving I was doing this should not have happened. These are bulldozed tracks no ruts or steps just flat tracks, the sticky bit I was referring to with regards to slipping was due to the incline, this is steep country but you couldn't ask for a better track.

Example of the terrain in this photo.



114772

A lot of loose rock but nothing big.

I'm putting it down to the low profile and brand of tyre being weaker in the sidewall. In saying that it still probably the best choice unfortunately for a 19" rim :(

Would you have used 42 psi in the other tyres or did you keep the pressures up on the 19" to avoid pinching the shorter sidewalls? At 42 psi the sidewalls wouldn't have much give. Lowering to around 30 psi may have been a useful compromise.

[ozscott]

It's not good Babs. I have done 30kph on heavy gibbers in Sundown National Park fully laden... Sharp hard rocks and no dirt... Just rocks. Combined with hours of slower driving on the same rocky roads. My Maxxis 751 LT are completely unscathed from that. Sorry to see the tyres cut mate.

Yes Graeme I have always kept the highway pressure on the previous tyres only letting down pressure for rock steps and driving up the rocky creeks. The tracks hasn't ever been any real need for the drop on bulldozed tracks.

And yes from research I was of the understanding that retaining higher pressure on the lower profile tyres reduced the chances of sidewall damage.

Trouble is when you air down already thin rubber the rims just look SO close to the ground. It's a conundrum because with them up the tyre will not deform around sharp objects and pop back... It is more prone to damage with full pressure. Likewise full pressure puts more stress and shock on the carcass, rims and ultimately suspension. Cheers

Been there in the D4,not heavily laden though,no problems at all;)

That area is the rockiest area i have ever driven on.

Babs,sorry to hear your woes,i also absolutely hate tyre issues with a passion.

That is the main reason i grabbed one of the last D4 2.7's,and shod it with BFG's.

There is some pretty good chatter on tyres on the LR Facebook site,in the D5 area,not that i am into Facebook,but one of my sons sends me stuff.

If you are into it,your recent experiences documented on there would be good.LR are monitoring it and responding to comments from the public.There are many comments about the D5 and 19" sizes,all negative from many D4 owners.

That second cut looks like it is down to the cords,which isn't good.

When I was trying to get my Hankooks to wear better, I ran in the 40's for a while, and during that time I got some sidewall nicks in the rear tyres like the first photo - also had terrible ride quality. The nicks could only have come from the unsealed road at my parents' place. I have since gone down to placard pressures (since the higher pressures didn't help anywhere near enough for the discomfort that came with them) and have had no further tyre damage.

[dirvine]

Being new to the D4, I am wondering what tyre pressures people have when going off road. Especially these Maxxiz tyres.


Eg F & R when in mud, when in rocky dry country, rocky wet and slippery country, and hard and soft sand.


In my old car with 16 and 17 inch rims I basically had 25 in any offroad conditions except sand where I dropped to 20.


Thanks


David

[Tombie]

Those pressures are a good start...

Remember David that it depends on other factors - the actual surface at the time, vehicle weight and it's distribution etc..

[dirvine]

I understand that Tombie but it seems these low profile tyres give people lots of problems. I am going down to the Vic High country to help the NP people with track clearing before the season opens and dont want to do damage to my tyres or rims, nor make a fool of myself trying to get up tracks with too much pressure in the tyres. Peoples comments have put the wind up me so to speak. Perhaps i should get the Great Wall out of retirement and then I wont have any problems.

It depends on which tyres you run as to how low you can go - the Hankooks have a more flexible/pliable carcase compared to the Maxxis, so you run a higher risk of pinching the sidewall with the Hankooks when at lower pressures. The Maxxis being LT construction should actually need lower pressures than other 19" tyres to get the same footprint, but should also be a tougher tyre in all instances.

[Tombie]

Well low profile tyres certainly didn't phase me all weekend.

We ran on gibber, climbed rough shale tracks for hours. Just kept the speed down - there were several other males in the groups I had tagging along - and suffered no damage or scuffing to any of the tyres.

All carried out at 28F and 32R

So the front stays at 33psi but that's obviously not taking winch & bar into consideration.

Rear fully loaded passengers and luggage 42.

I am going to change my pressures to 36psi front & 38-40psi rear.

33psi front seems a little low and 36 rear the same ❓

I have always run my previous tyres 40psi highway pressure and due to the conflicting information on these 19" rims thought raising the pressure was a safe bet. Obviously not. :O

Cheers, Babs :D Sent from my iPhone using Forum Runner

[jon3950]

As Tombie has said, speed and pressure are the big issues. This can't be emphasised enough. The 19"s will work ok but there is much less margin for error.

I think the placard pressures are on the money, maybe with 1 or 2 psi extra but no more. You need to add a bit more to the front with a bar and winch.

Off road I used to work on a 4psi rule. Whatever my road pressures had been for the weight I was carrying I would drop it by 4 psi. If it got particulary rough I may up that to 6-8 psi but no more - that doesn't include sand of course. That would give the carcass a little more compliance on and around rocks without letting the sidewall bag.

I did a lot of miles in the High Country using that rule and never had a problem up there. Just take it easy and you will be pleasantly suprised how far the Disco will take you.

Driving home M2 I didn't pay attention and didn't notice any difference until I got to my area (rural roads) where the roads are a little rougher and then noticed a substantial difference, the ride was so much smoother, it felt like I was still on the M2. :)

Probably hard to quantify.

My vehicle is never lightly loaded [emoji6]

Fully loaded doing the Transcontinental I had pressures at the same numbers.

High pressures kill tyres on gibber. On the mine sites I was the person with the least punctures over the time I was there as I was the only one to air down...

I agree Tombie and assumed it was to achieve the same contact patch between front and rear axles.
The front axle is less loaded than rear axle, especially when at travelling weight. This is perhaps less of a factor if you have a bullbar and winch.

A very experienced racing driver gave me sage advice years ago about my mx5 tyre placard. "The pressures on the placard are the minimum pressures and they are set as low as they can safely be to get the most compliant ride for the occupants" his advice was to go 5-6psi higher on those little low profile mx5 tyres (this was before hitting the track though)

Race Track pressures are basically the opposite of off road tracks - on a race track you want higher pressures so tyres don't heat up too much, you get sharper turn in with higher pressures and also less side to side sidewall movement around corners. On road you don't want/need any of those benefits of higher pressures.

You seen some of the pressures the guys in V8 supercars use when starting out? A lot lower than you'd expect at a mandated minimum of 17psi (which they indroduced a while ago on safety grounds as they where being run lower) - but then again they do that so the tyres heat up quickly and get to correct running pressures sooner and they also run a hell of a lot hotter than road tyres

Some do want the higher pressures to maximise fuel economy,on road.

I also find AT/LT rated tyre pressures need to be higher than same size,vehicle,etc as P rated,as they seem to run hotter.That is on road,particularly at high speeds.

They also run tyres that are constructed differently to road tyres.

[Garfield]

I note most of the chat on this thread relates to tyre pressures for 19" tyre/wheels.


As my D4 has 18" BFG Ko2 LT tyres and is always loaded to a certain extent ( bulbar, winch, drawers with tools, recovery gear, axe, air comp etc ) with road day to day driving , any views on suitable tyre pressures for both on sealed roads and gibber type roads ? Currently run 40 psi back and front for around town - which seems to give me reasonable handling and fuel economy. And as for ride comfort, it seems much the same as the original Wrangler 19" tyres

[RobA]

OK given this seems to have turned to pressures some of our experiences after 4 months on the road fully loaded, towing an Ultimate camper. D697s on GOE rims on the car and Cooper AT3 on the camper

On the road(bitumen) and fully loaded. That is the car weighed around the same as with 7 people on board and we had the 3JC on the roof full most of the time plus a second spare, space case with tools and bits and pieces, 10l of petrol for the generator. I mean fully loaded.

Fronts 46 and Rears 52 with trailer matching fronts

Once we left the bitumen and this meant everything from the Finke Track, Kimberley, GRR, Mitchell Falls, Cape Leveque etc.

Fronts 28 and rears 32 and trailer matching fronts

Back in Adelaide and for around town and general travel duties, 32F and 34R

The wear pattern on the tyres was consistent across 22,000km and when we checked in with our Bridgestone tyre engineer his only comment was the wear pattern indicated we were heavily loaded. Won't bore you with how we get to that but my appreciation of that pattern and its explanation helped me appreciate even more how much development goes into manufacturing a tyre

Hope that all helps but clearly from this discussion and many others on this forum, we all drive differently and have vastly differing expectation and approaches to how we manage the four round black sticky things that keep us off the ground

Thanks for the feedback/information Rob - very interesting. I'm quite surprised how low you could run the pressures on dirt road with such a load on. Maybe I should give my 18' KO2's tyres ( LT ) more credit for their strength and not so reluctant to low pressure on them.

One of the things we have learnt from around 20 years of off-road exploration and remote area touring is exactly what you just said. Folk are really reticent to lower tyre pressures to where, IMHO, they realistically should be. The end result for some/many is vehicle damage amongst other things. I reckon we have done over 20 crossings of the Simpson Desert to start with. Combined with the amount of testing we have done for a range of 4WD suppliers/manufacturers our data base is pretty large. On our tours we normally have around 8-10 cars and we collect data on tyres, pressures, vehicle weights and performance on all of them over an average 14-21 day tour. So once again we know rather than guess on performance in varying conditions.

All I can suggest is to give it a go. Collect your data including vehicle weight on specific occasions, it becomes intuitive after a while as you really get to know your car. Without the data it remains guesswork.

Pick a track you regularly use and make the changes record them and see how it goes.

I have to say most folk don't get as close to tyre manufacturers as we have the privilege of doing. This gives us a pretty solid appreciation of how each tyre is manufactured and I can assure you it is a complex process with a great deal of modelling and testing being done before the gear we use even comes to us and others for field testing.

An LT tyre for example is made strong across the tread face and sidewalls. That by design alone brings additional weight. The associated trade-off is normally around a 2% increase in fuel consumption. Not all LT tyres are made the same way. Some are made smarter to retain strength and balance that off against a significant increase in weight. As always there is no such thing, yet, as a puncture proof tyre. I can assure you they are around but there are significant penalties and from a commercial/retail perspective a long way from production.

So don't get me started on tyres

Just have a crack at going lower off-road and collect start point data, make sure you have a decent TPMS to help with that and use your calibrated seat of the pants and see how it goes. But please remember that lowering tyre pressures comes with an associated reduction in speed. On the GRR we rarely got above 90 kph. But that is about the same speed we always sit on when travelling the Oodnadatta track and others around Central Oz amongst other places including the Cape

I will be most interested to hear how you go

Regards

Rob

Basil135 and I drove to Nullabor to collect those wheels and tyres from that vehicle - they had another set sent over and just swapped and dropped - the damage was not to sidewall it was all in the tread itself.

All damage was stones through the tread between the blocks, the tyres themselves were almost full tread when we collected them.

An LT would be substantially stronger - and were not available at the time it was filmed.

From memory Duratracs in 255/55R19 are only 4 ply I think? And no ply rating either.

[ozscott]

I have heard that the PR Duratrac has a soft wall. The Duratrac in an LT is much better. I have used the LT on a non-LR (yes I know... Can you believe it) and they were great. Cheers

[Garfield]

Thanks RobA for your great advice on tyre pressures - I .will certainly try some different pressures with the LT tyres on both dirt road, and 4WD tracks. As mentioned, not only have I been a bit reluctant to try lower pressures, but also the hassle of deflating and airing up with an external compressor and unpacking it from drawers , connecting to battery etc


I may look at installing a compressor permanently in the engine compartment. I saw one thread where a member had installed a compressor in the drivers side black fuse box. Any suggestions for a good small compressor to fit into the fuse box, as I want to leave the other side for a dual battery system.

Yes, watch the video closely. It does that when it goes flat from a previous tread puncture.

I spent ages shuffling back and forth watching the video to see what was going on.

[Tombie]

See where it is also - right on the transition.
**** weak wall, not a pinch injury.

A 16" rim would still have exposed that part of the tyre to the surface. However the 16" has a PR and is significantly stronger in that area.

As I said, a true 19" LT will be much stronger at that point.

[PerthDisco]

Just got back from 3900km run up to Karajini, Wittenoom and home via Mt Augustus. We did over 1500km on rocky dirt tracks. We ran a combination of road pressures and low 30s for the long dirt run from Tom Price through Mt Augustus to Mullewa. Some very rocky sections running at 90 to 100kmh. Only problem was my mate's Prado that lost two Cooper ATs including this one https://www.aulro.com/afvb/images/imported/2016/10/599.jpg

https://www.aulro.com/afvb/images/imported/2016/10/600.jpg

The first flat was a small hole in the tread but it ran flat long enough to ruin it. The tyre shop in Tom Price only had LTs so he had to buy two and put them on the back axle. This next flat happened about 500km on dirt roads from Meekatharra so he was pretty upset to be back to no spare again. Made us think about the benefit of two spares.

It was also about 37 degrees so changing is no fun and I was thankful not to be unloading the back of the Disco. The Toyota is a neat operation and good jack.

My other mate had a brand new D4 with stock Wranglers no problems.

Other colour options for the Compomotives get away from that look. However I'm a function to the neglect of form person so any lightish colour would be OK with me.

[Garfield]

I'm not a great fan of the style or colour of "my" Compomotive 18" wheels, but they are there to perform a certain function - and that they due ( at cost of significant $$$$$$$$$$$$ ). I firmly believe LR should have provided an option for 18" OEM LR wheels ( for a $100,000 4WD ) for the later model D4. Whilst I understand 19 and 20" wheels are far more suited ( and athletically pleasing ) to sealed road handling, LR pride themselves on manufacturing very 4WD capable vehicles.


That's my "bitch" about wheels for D4's he he he :)

[Garfield]

And LR needs to put much larger capacity fuel tanks in the D4's. They managed to put larger tanks in the Range Rovers, so why not D4's ???

So the wheel balance issue has been sorted. But there still seems to be a shudder in the driveline. I can't feel it through the steering wheel so I would assume to rule out tyres.

That alone does not explain the jump from D3 to D4. They both tow the same caravans at same speed and braking was not a problem.

The bigger brakes indicate a top speed performance orientation which I don't imagine owners are buying the cars for.

IMO LR were lazy in development of the larger rotor size on the D4 and went for a cheaper 2 pot caliper with large ribs over the top of the caliper compromising clearance. There are plenty of 4 pot calipers around for similar size rotors that are much more compact. LR could have used these (off the shelf Brembo for example) and stuck with 18" wheels. The 4 pot calipers have the same effectiveness as the OEM calipers, it is all about ensuring total piston area is maintained.

The Brembo calipers on the RRS (with same size discs) need an anti vibration piece removed so that the compomotive 18" wheels fit. Pretty sure the LR 18" still don't fit with this minor modification

[cjc_td5]

The fins would have a cooling effect but they also have a strength function to transfer forces between each side of the caliper. My Engineer would not ok their shaving/removal.

Goes to my point that the "Best 4WD in the World" is more interested in glossy interiors and bling than a braking system that can accommodate off road tyres. Sex sells, as they say.

I still say if it was good enough for the D3 there was no need to change it as towing capacity did not change nor did all customers move to outback NT for unrestricted speed limits.

But power and torque did(3.0l),and so did the terrain response system,which is different from the D3.In fact the later D4 system is different again,as Gordon(GOE) has said,almost negates the need for the E-diff.

Yes, maybe you can accelerate 0 to 100kmh faster but still braking from 100kmh like a D3 with same weight and not many would need to pull up from terminal velocity. That is where LC has got it right IMO as the extra power makes towing effortless for almost no downside in stopping ability for the average punter.

And let's be honest that when you most use TC you are doing walking speed so hardly need massive discs.

Another sidewall casualty. This time a Chinese tyre (HL rated... But Chinese HL rated...) at Sundown on 19 in. Would be better with LT. Fact remains that the sidewall is a lot lower to the ground on an aired down 19 running 255/55 than on a 245/75 on 16's. We were running 25 pound. On a 16 suitably aired down the bulge is less severe and has a more gentle curve up and out from the tread... So less prone to damage. Anyway my mate knew if would be a close run thing in Sundown with those tyres and it was. He will now move to the 980 in LT. Cheers https://www.aulro.com/afvb/images/imported/2016/10/48.jpg

I agree,strange a LC200 can run 17's,with no issues.

Audi TDV8 can run 18's,as i have said before.

Anyway,it is all academic,we could talk about it for ever,LR have done it,all history.

And the new model D5,they only thought about it after it was released,shows how much they care about the issue.

[PerthDisco]

Fixed something not broken is my conclusion.

[Tombie]

Fixed something not broken is my conclusion.



Building the best in class TC that can handle the torque requires bigger brakes to both hold the vehicles torque and dissipate the heat generated..

The LC200 is horrendous.. poor braking without a trailer let alone with one.. and a mediocre TC system at best.

[Geedublya]

My V8 with 510 NM and the smaller brakes can overpower the TC fairly easily. You just have to be aware of it and be careful applying the power. This isn't always easy in some situations.

I'm unsure how well the larger brakes coped as I never used them off road.

[ozscott]

OK my mate (I was in his D3) lost the tyre going into Sundown and it seems bloody close to another on the way out. With Sundown National Park it's not the size of the rocks but that they are bedded in hard and are sharp and we all probably travel quickly on them. Cheers 115979

V8 has bigger brakes I thought minimum 19" wheel? Could be wrong.

It's always a trade off for sure but I would imagine only a poofteenth difference between the 2.7 TDV6 size and current size considering the rears are the same (I think).

Im not suggesting following the LC200 lead but if the 2.7 could take 17" then no reason to make the min acceptable size 18" in the current guise notwithstanding what a wonderful secondary wheel market it has created for GOE all credit due! [emoji106]

I have just come back from the Victorian High Country. First time my Disco has had a serious outing. I have the maxxis tyres and lowered tyre pressure to 28psi all round. We went on the following (significant) tracks. Burgoyne, (crossing the Macallister River, Mt Margaret (both up and down), Dingo Hill, Butcher Country track. Caladonia River Track

My biggest gripe is the fact that my rims have severe scratches and chips on the edges. The size of this rim and the small profile of the tyre are the most stupidist things LR have done. Why build such a great 4WD and then not allow it to have decent 4wd tyres fit. The real issue is the profile size in that it does not allow the tyre to bulge out and therefore help to protect the tyre rim edge. I'm all for bigger brakes and a great TC system, but LR really should have looked at what tyres would be able to fit and be suitable for 4WDing as well as being safety compliant. If they just could of had a 65 or 75 profile tyre it would make a world of difference. Then make sure tyre manufactures would make a LT tyre for AT and Mud.

Otherwise I am more than happy with the way the car performed. Completely different to the run of the mill 4WD's and so smooth. Generally I can tell how rough a track is by how much my 44 year old Engel fridge clunks. I hardly heard it. Cannot wait for the next "adventure".

[tonyci]

Agree with you're comments re LR. I solved the problem by buying new rims from GOE.
How was the high country very wet I assume ?.
Cheers

[dirvine]

No Tony it was very dry. On Saturday and Sunday it was warm and very dusty. Then on Monday morning we had snow!! Go figure typical Victorian weather!!. The Macalister was at bonnet height in some places and flowing strongly. As our crossing was up stream and only the deep part near the exit it was not too difficult. I dont have a snorkel, but the car bra worked OK. I know I could solve the tyre problem, but thats another $3 -$4K outlay, that really should not have to be expended. I accept that we all have tyre preferences, but not having to buy rims as well. With other brands, people buy bigger rims to fit bigger tyres to usually get more clearance, We are almost doing the opposite!

[ozscott]

The tyre sidewall should not protect the rim. The sheer height of the rubber and the tread should protect the rim. The sidewall simply should not be vulnerable in the first place. It is the sharp angle from the tread and the closeness of that angled section to the ground when aired down that leads to problems with sidewall cuts. Cheers

[Tombie]

Only 7mm!![emoji32]



Yes, and that can make all the difference..

Regardless, as I mentioned earlier, the LC200 struggles to stop at the best of times compared to a D4..

And the other factor is repeated applications... a D4 can e-stop several times with minimal/no brake fade...

Having driven LC200s for work - they aren't a confidence inspiring entity when it comes to stopping - the only people who would think their brakes are good would be Series Owners!!!

[cjc_td5]

IMO the whole 19" wheel argument is getting a bit tired and is diluting the intent of this thread in particular.

We seem quite OK with modifying our vehicles in all manner of ways from standard but moan consistently about the wheels! There are ways to mitigate this, being GOE (or other) wheels, tyre selections or brake modification to fit smaller wheels.

Let this thread continue in review of the Maxxis tyre option. Carry this discussion elsewhere in the myriad of threads already created on the topic..... :)

I understand your feelings towards the gripe of 19" rims but it's not as easy as what you say in regards to other modifications.

With other modifications there is a broader choice of accessories, however the 19" rim really is a thorn in the side of a Discovery. If there were higher profile LT tyre choices then this would never be a concern and you wouldn't read a mention of it. Unfortunately going to an 18" rim is extremely expensive for some and you don't get a choice to what is available.

So I understand and side with the gripe of the poor decision/design of Land Rover going with a 19" rim. It's appalling!
Me personally I'm happy to read other members gripes on this topic.

Anyways as you wish back to the tyres..........

[Babs]

Maxxis update, had them off road again this weekend, same tracks as the last update when I had the two sidewall stakes.

I took the advice from here and lowered the pressure I ran back at 25psi and front at 23psi traction was definitely increased and I pushed them over rougher terrain than last time when I had pressure up.

At a brief inspection there appears to be no damage but I still have to give them a clean and do a more thorough inspection.

So at a glance the lower pressure is more productive contrary to the mixed info on keeping higher pressures to protect the rims and tyres [emoji3]

I have to agree with you totally Babs. for a vehicle with this 4WD capability, 'LR" should provide wheel options, and not just left to only one aftermarket expensive wheel option ( Compomotives - which I did reluctantly go to the expense of purchasing) . LR pride themselves on there history of making 4WD capable vehicles - so why stop now by not providing an affordable wheel option when you purchase the vehicle new. Just my opinion too ...

275/55/19's on the driver said great tyres however they seem to be a tyre for colder climate and snow with a max psi of 44... also 255/60/19 there are a few tyres but similarly seem to be for colder climates...

[Pirate_Pete]

Another sidewall casualty. This time a Chinese tyre (HL rated... But Chinese HL rated...) at Sundown on 19 in. Would be better with LT. Fact remains that the sidewall is a lot lower to the ground on an aired down 19 running 255/55 than on a 245/75 on 16's. We were running 25 pound. On a 16 suitably aired down the bulge is less severe and has a more gentle curve up and out from the tread... So less prone to damage. Anyway my mate knew if would be a close run thing in Sundown with those tyres and it was. He will now move to the 980 in LT. Cheers

I took my newly acquired D4 SE MY13 into Sundown on the 29th of Oct as this is where I seem to gravitate to with any 'new' 4wd to see how they rank. As time didn't permit a full day of play I just took the Back creek track from the ruins around to Red Rock Gorge then back out the normal track. This back track would have to have some of the hardest rocky track conditions I've played in. The car has Cooper Zeons which seem quite good to me (so far) as they grip on black top and gravel, wet or dry, and very importantly after living with BFG's for the last few years are absolutely quiet.

I'm quite concerned with the 19" and low profile tyres and have over the last few hours read this entire thread. At the end of it I really am none the wiser, except I see that I'm not alone in wondering why LR has chosen this path.

One question based on an observation from last weekend regarding pressuring down the tyres for that rocky type of surface. As we towed our ~2.5T caravan to Girraween for the weekend, my tyre pressures were 36F38R and I didn't drop them in Sundown. One of the spots that I got out of the car to look at the obstacle in front I noted that the front right tyre was half on a rock of around 200mm in size. With the vehicle's weight being supported on approximately 1/3rd of the normal contact patch the sidewall was was rather compressed and made the tyre look flat. That's with 36psi, had the tyre pressure been lower then the only thing between the rock and rim would have been the rubber.

Do we really feel that it's a good idea to drop the pressures on these low profile tyres? This experience suggests not to me, but I don't profess to be an expert. Coming from 16" wheels (Pajero, BFG AT) which had a comparatively huge sidewall I'm struggling with the risk of rim damage due to under inflation on such obstacles...

Also I see that we don't really like the Zeon's, can I please get some feed back on what the issue is with them? The original owner of my D4 swapped out the OEM tyres when new and the car is on it's second set of Zeon's, and he has done the same with his new vehicle, so he obviously likes them...

So far (only done 3000km) I've been running them at 36f36r for normal road work and experimented with 38r last weekend with approx 100kg in the boot family of 4, caravan ball weight ~250kg, ARB Summit bullbar and winch up front.

Cheers Pete

Not much feedback on Zeons lately but in this older and very long running thread ('12 to '15) you will find feedback on them and other 19s both good and bad.
http://www.aulro.com/afvb/l319-discovery-3-4/147230-d4-19inch-cooper-zeon-ltz-255-55-19-a.html

I think finding the "right" pressure will always be tricky with 19s because with less air volume comes increased sensitivity to pressure.
And consequentially increased sensitivity to the type of surface, particularly with rocks. True LT tyres should alleviate this to some extent.

Cheers,
Scott

[hv_man]

Going to the 18" compomotives would also be one of if not the most expensive mod one performs to their D4. It's considerable $$ hence the focus.
If the rims where cheap we wouldn't be having this discussion we'd just buy them and move on to the next mod like other makes.
Unfortunately for now we're stuck with one solution. (We don't speak of the other)
A premium rim from a premium manufacture at a premium price.

I'm keen to give the 980's a go, but I know in the end I'll probably end up going to the compomotives.

Oh,and a set of 17's thrown in:)

[Babs]

Right that's it, I've bloody had enough❗️

Back at farm this weekend, I had tyres down, front at 22psi and rear at 24psi. Same bulldozed tracks and a creek crossing and I have another gash in the rear so now I have 3 gashed tyres in the sidewall [emoji35] I'm as Mad as a Cut Snake.

This is ridiculous almost 30 years no sidewall damage (well one but that was inevitable) and now 3 on these Maxxis.

I don't know if it's the tyre itself that it's crap or it's the sizing [emoji780]

Either way they're not making the grade.

Time to bow my head, swallow my pride and empty my pockets to go with the GOE 18" rims. I gave these Maxxis a go and they didn't perform now time to go back to the trusty old BFG OR Coopers.

[ozscott]

Bugger mate. Can't comment on the 19 in Maxxis save to say they are not as HD as the same tyre in 16inch...

The carcass on the 19 is a 115 load rating versus 120 for the 16.

Cheers

[scomac]

That's not good Babs! However it is interesting that I traveled the 600km GGR fully loaded and towing a 1200kg CT and not even get a chip or cut let alone a slash in a tyre. The gravel road was not only corrugated but definitely a lot of sharp rocks around.

So I think it could only be one of two things;

1) Your just bloody unlucky.
2) It's your driving style.(as in you can't drive on the 19's like you would a 17")

Hope you have better luck on the 18's.

Cheers
Scott.

[JamesH]

That's terrible news. Mine are fine but I haven't challenged them, so that's not relevant.

Have you considered going back to the shop, could you have go a crook batch?

These tyres are supposed to be the solution of 19" tyre choice problem but for it seems to have been the start of the problem. :(

[letherm]

Have you considered going back to the shop, (

Hi Babs,

That's a bad result for sure. I think I would be at least raising it with the tyre seller too. You may at least get some goodwill rebate. Tyres should last better than that. You can understand 1 going but this is ridiculous. :(

Now here's me having convinced the Cook we should flog the Deafener and get a D4 and this tyre/size/choice rears it's ugly head.
We love to go remote but I'm damned if I'll be doing that on 19s and I don't really want to be shovelling heaps of money GOEs way as soon as I get one.
I reckon a rethink is on the cards and maybe the darkside will get a revisit.:o
AlanH.

PS. We had a good run with a Prado for over 4 years and the Cook has reminded me of that..... :p

[Babs]

Well I just ordered my GOE rims today, with air freight they got up there in price.
The cost will keep going as I now need a rear wheel carrier, and seen as it's empty under where the spare goes I suppose a long range tank will be in order :o

Now to decide wether to go 265/65/18 or 275/65/18

[Graeme]

You could go 265/60R18, available in various brands including BFG KO2 and still fit a spare underneath.

[Babs]

Thanks for the recommendations on going back to tyre shop, I don't really expect to get anywhere with that :o

[LRD414]

You could go 265/60R18, available in various brands including BFG KO2 and still fit a spare underneath.

Exactly what I'm currently running and very happy with so far including some nasty rocky tracks.

There's even a couple of MTs in 265/60/R18 that get some good feedback if you're that way inclined.
Eg the Atturo Trail Blade.

Thanks Graeme, but I'm a little paranoid now and want a larger sidewall I want to stick with a 31.5" or 32" tyre.
Gordon commented that the 32" tyre has a noticeable loss in power so maybe the 265/65/18 (31.5) might be the go.

I like the look of the new KO2 but not sure how proven they are yet so I'm sticking with what I know works, the Cooper STMaxx.

I like the look of the new KO2 but not sure how proven they are yet so I'm sticking with what I know works, the Cooper STMaxx.My 20" KO2s with their wide tread but slightly less sidewall height than 265/60R18 are proven to my satisfaction after 30K at gravel road pressures and not pussy-footing around at all. IIRC BobD has been running 285/60R18 KO2 for a while now so can comment on that size on a D4.

[BobD]

Yeah, I'm loving the 285/60 K02's.


My son's D1 and my Kimberley Karavan also have K02's. We all did a 14,000km trip on them earlier in the year (Great Central Road, Birdsville Track, Savannah Way and others) and they performed very well on all three vehicles. The only issue was that one of my rear tyres got a few small chunks taken out of the tread towing the Kimberley Karavan into the Bungle Bungles. However, that has happened on my old D697's in similar circumstances also, with a lot more chipping on the D697's than the K02's. I find that the D4 is very hard on rear tyres on rough roads when towing. The fronts stay like brand new.


They are pretty quiet, very strong and the car handles better on them than any other tyre so far, probably due to the slightly stiffer sidewalls. I have full confidence in them off road. The sidewalls are very thick and well protected by the wrap around tread / side biters. No punctures so far.

Good feedback, thanks.

Bob do you have Llams [emoji780] if so do you get any rubbing on the guards on the Llams extra low setting when turning or do you get any rubbing on guards on the factory low setting when turning [emoji780]

Gordon has informed me there is slight rubbing on full lock internally but I'm not sure about the flares/guards [emoji780] cheers [emoji482]

[BobD]

I mentioned it on your other post re tyres but will repeat here.


My tryes rub on the inside of the rear guard on the seam as per Gordon's web site. I haven't bent the seem so there is a hole through the plastic liner.


They rub on the chassis extension behind the front wheels when in reverse, as per Gordon's web site. They also rub on the front left when turned right at the front of the wheel arch, mainly due to reduced clearance because of my ECB bar. I can't see how you would fit any bigger tyres than these without a lot of rubbing and both of the tyres you are looking at are bigger in diameter, if not width.


I would go with 285/60 R18 K02's if I was you. They are very good, if expensive. Otherwise, Kuhmo.

[Babs]

Thanks Bob,

I'm looking at 265/65/18 the same overall diameter I think 2mm difference but the 265's are a little more narrow, I'm hoping this would reduce the rubbing issues :)

I think the KO2 is the best looking AT on the market at the moment but I'm swaying towards the Coopers because of previous experience with them and can't break them.

Thanks for doubling up your reply in threads, most of the time I'm using the app on the go always from my phone, and having a memory like a goldfish doesn't help either. Appreciated Bob.

One more thing have you noticed a decrease in power [emoji780]

D3 looking a definite keeper [emoji10][emoji1305]



If nothing's broken or just some small maintenance items then why change?

Consumerism is all it is..

You can modify and improve the D3 for years before you get close to the cost of replacement.

[BobD]

Thanks Bob,

The rubbing is nothing to do with the width, just the diameter. You will have trouble fitting any larger than the 285/60 or 265/65 tyres.


It is impossible to notice a decrease in power without going straight from one car to the other I would say. I haven't noticed any lack of power but I'm sure it would lose a drag race to a car with OEM tyres.

[Babs]

Another Maxxis update.

Yesterday had the wholesaler or looks after Maxxis file a warranty claim, outcome still to be determined, he is happy it's a legitimate claim just what they will come back with is unknown.

Interesting conversation with him though, he said that the Land Rover placard is wrong and that under 40psi is too low pressures.

He recommended 42psi front and 44psi rear [emoji780]

Also recommended not to drop pressures off road or dirt roads, only time to drop pressure is when there is a noticeable loss of traction.
He said dropping them bulges the sides and makes them vulnerable for stakes/cuts in sidewall.

[emoji780] [emoji780] [emoji780] there are so many different opinions on tyre pressures, what to and not to do sometimes I wonder if anyone really knows what their talking about.

So for now until my 18" rims arrive I'm going back to 42 rear 40 front. I think that's a happy medium.

[Jaybee]

Here's an interesting Video of the Discovery 4 crossing Baboons Pass in Africa where the experienced tester/presenter recommends running the General Grabber AT 19" tyres fitted at 3 bar (43.5psi) to avoid cutting the sidewalls and allowing the terrain response to do it's work to overcome any slippage. Interesting to see how scratched the rims are and if this was the result of only one trip then you are justified in getting 18" rims for off road work.

[ozscott]

It's all very interesting and traction control is good stuff for sure...bit without a shadow of a doubt the most effective way to climb up or over an obstacle is not to lose traction in the first place (or to mimimise its loss) and the best way to achieve that is to lower pressures to achieve maximum traction... so if not lowering then you are not getting the best out of your vehicle irrespective of make and model .Cheers

[Fatso]

Tend to agree re tyre pressures , did a bit of seismic work in the canning basin running the seismic lines in another life , these lines go dead strait for miles and miles over ridges and sand dunes and are mostly sand all the way. No traction control or modern trickery back then .
We sometimes did let the big super single tyres on the big Isuzu 6x6 water truck down over some of the bigger dunes but other wise left the tyres on the 4x4 at normal pressures and learnt to keep out of trouble , certainly less staking of the tyres with the more flatter side walls .
Still use the same method today when out in the scrub , any way, time for a tooheys .

[Babs]

Ok so I got the phone call today, Maxxis are only replacing one tyre, the two original slits that I got first time round won't be replaced as they don't think are deep enough to be a concern.

So I'm going to let them replace it then I'll bring the brand new spare forward so there is two brand new spankers and two with 16k klm on them and then there up for sale, if anyone is interested [emoji780]

[Jaybee]

Are you selling just the tyres or complete with 19" rims?

[Babs]

I was going to keep the rims for the ever just in case tyre manufacturers start making a wider choice of LT tyres in different sizes and also for resale down the track.

[rambada]

I fall into the 'let pressures down' camp. The other day I was lazy on the beach/soft sand and you could tell the car was working really hard. Also didn't do it in some super bad mud/rain one time - and went off the track with no control. Big stamp on forehead - never again.
Its also better for this awesome environment we all love here in Oz.

Enjoying my Maxxis - may be my imagination but they are wearing a bit though. Time & $ will tell.

[Tombie]

Premium vehicle with an alloy option that is made to suit a lower production volume and the price difference between an ROH alloy for a Land Cruiser and the Discovery is a total of $1k

Plenty of Cruiser owners shoving after market alloys on their vehicle...

When out in context of volume vs cost the minimal $1k difference seems pretty insignificant.

After all you're not $5k out - you were always going to swap rubber so remove that from the equation... you're $2500 out on rims vs the Toyota owner who is $1675 out of pocket for his new alloys...

[David47]

Fitted new Maxxis LT255/55R19 to our Discovery 4 today after an unhappy weekend in the Snowy on the original Goodyears.

Ready to change my set of HT tyres on the D4 and have been doing research on what AT's to get, clearly limited in 19" and not so keen on the additional $$$ for 18" rims.

From reading all the posts looks like the Maxxis might be the way to go? I'll keep researching but its almost becoming a toss of the coin. (Cooper, Grabber, Hankook, Pirelli, Duratrac)

I've got the Cooper and they work, but my driving is mainly Road, beach and limestone access tracks of WA. So far I've managed to avoid destroying them but I think the rears are wearing quite fast, but that might be wheel alignment more than the tyres as I can detect some feathering in the sipes, so I'll get it aligned.

Hi Chris, depends what sort of driving you want too do on them. The Maxxis give you a little more of a harsher ride and are a little noisier(IMHO) If you don't plan on doing any hard rocky terrain, all brands will be more than suitable.

Mainly sand/gravel but towing a camper trailer so traction (rubber on the ground!) is important to me - the HT's that are currently on have served me okay, have been stuck a couple of times but have always managed to get out un-assisted.

Going a little more remote soon and want a bit more security with a good set of tyres, think ill give the Maxxis a go and live with a little more road noise.

The more remote you go the more that strength, particularly in the sidewall becomes important in addition to traction. These are the only LT spec of the 19s (as far as I know).

Agree, i'll let you know how they perform once fitted.

I did the GRR on the Maxxis with no punctures, tears or chips so you will be fine.

[David47]

We've just completed our first real trip on the Maxxis - 2 weeks in the Flinders Ranges - a total of almost 4000 Km (from Canberra).
The D4 towed our 2T van to and from the Flinders, averaging 16 l/Km. The Maxxis are certainly noisier than the original Goodyears on tar but not intrusively so. Steering and braking were not noticeably affected.
Once there, we camped on several stations and did day trips in the D4. The tracks varied from open, dusty, high-range drives to tight, steep, rocky, low-range crawls. We could not fault the tyres on any of the surfaces. A highlight was a day-long drive 'Sky Trek' on Willow Springs Station - well worth the fees.
Widely differing information on tyre pressures led us to use 40/45 on tarmac (pulling the van) and 33/38 on the rough stuff. Seemed to work OK.

Hi Scott.

What pressures did you use on the GGR and other gravel? Were you towing? All going well I'm doing the Victoria River district (similar to GRR) and Great Central road (not towing) in June/July.

Won't be towing and have driven those roads before. Know to keep speed down though that's easier in a tdi Defender than one of these rockets.

Hi James,

From memory I had pressures at around R36 F33 fully loaded and towing 1.2T of CT and speed at about 80kph. Which was hard because I was following a mate in his Prado who was struggling at 60kph.

Thanks, Scott. I'm glad you had a good experience with your Maxxis. I got them to handle just that kind of traveling with minimal unloading the back of my car to get at the spare. 10k in and Ive only done about 5km on gravel [bigsad] but with luck this will change. They certainly look the business.

cheers James

I'm still debating whether to change the existing tyres soon or not but will probably leave them on until I plan a decent off road trip. I like Maxxis as I had them on a Prado (17 inchers though) about 5 years ago and they performed well. Much more supple in the side wall than BFGs and you could really feel the difference in ride.
The 19s look to me like they could do with a extra line of tread around them but if they perform well as they are I'll certainly be looking at them later.
I'm following this thread with interest.

As this Maxxis thread has developed into a defacto R19 site, I make this post. After much investigating I ruled out the Maxxis in favour of the new General Grabber AT3 that now replaces their previous AT. I have been waiting for 3 months for the release and hassling various tyre retailers in Perth for availability and finally Richards Tyre Power fitted them yesterday. They have replaced my Pirelli Scorpions ATR after 36k towing a Kimberley Karavan and rears did not stand the abuse very well. From the international reviews I hope the new AT3 may be the sweet spot, for me, between the "soft" Scorpion and the "noisy" Maxxis. I am leaving for the GRR next week so should be able to report in June how they go. The AT3s were quiet and comfortable on metro roads on way home, similar to my old ATRs.

So, I'm gleaning that you decided to go with the General Grabbers because they were a bit more "user friendly" than the Maxxis on the bitumen or are there other reasons? Too late for me I have gone the Maxxis and they are definitely noiser than my (silent) OEM Goodyears. At the time there was not enough info on Grabbers for me to make the call, the Maxxis came out with LT construction just as I was in the market so I took them. A mate has got some General Grabbers on his D4 but that would be the old model. He loves them so far but has not tested them on a rough road. The trip we take along the GCR and then Buchanan Highway in July will be a good comparison and where they get tested. He will be towing a camper trailer but I won't, so it will be good to see how we go.

Honestly if he goes alright on the Grabbers, even if my Maxxis are also good, I will be sorely tempted to put grabbers on next due to the noise of the Maxxis. I don't hate them, but I'll take a quieter tyre that does the job.

[Tombie]

The General AT3 is only XL rated (111) so a different tyre....

If that's the comparison you can look at Goodyear Duratrac Etc as well..

If we're taking LT construction that's very different.. and partially why they are a bit noisier [emoji6]

Hi James
I could see the advantages of the Maxxis LT capabilities but as my driving is 80/20 (bitumen/gravel or sand roads) I was concerned about loosing some of the D4 advantages of covering distances with ease in the big tours we are doing in our early retirement years. I wore the OME Goodyears out at about 40k, 15k after I brought the D4. They were not coping with the Kimberley Karavan very well. The Pirellis were a step up but I got 4 slow punctures in the Pilbara last year and the tyres also got badly chipped but that was mainly on a road under construction between Mt Augustus and Tom Price. So yes I do see, at this point, the GG AT3 being more "user friendly" than the Maxxis and also a little "stronger" that the Pirelli. My mechanic has a customer who got 100k on bitumen out of the old GG AT so I hope I can get better the 40k mark. I think the Karavan's weight and independent suspension are hard on the D4 rear tyres so 100k is not even thinkable.

I have just put BFGoodrich KO2s on the Karavan replacing old KOs so this years big trip will be a real test of the new tyre designs. I invested in a 8 sensor TPMS to help protect the investment. They are the valve cap type so got short rubber valve stems fitted to better keep them out of harms way.

It will be interesting to compare our tyre tests later in the year.

Towing anything slightly heavy is hard on the rear tyres of any vehicle including full-time 4wd vehicles, let alone towing on gravel.

I assume that fitting KO2s to the van is purely for their casing strength rather than anything to with their tread pattern. Their tread pattern is a disadvantage rather than an advantage on the van unless they can be used as spares on the tow vehicle.

Hi Graeme
My trailer KO2s are on 16" rims as the Kimberley 2 ton bearings are incompatible with LR small wheel centres, although Kimberley is about to release a LR, VW, BMW etc small 2 ton hub this year. This is good news but will be expensive to retro fit but possible. New van coming up??? Kimberley also moving to ventilated disc rotors to reduce fade. Till now, they have recommended LR owners sticking to steel rims at 16" and not encouraged using alloy rims. They appear to be softening this position in response to customer demand and auto manufacture trends. The owner of Kimberley is also a Range Rover owner so this has helped them understand the benefits of compatible tyres and rims on tug/trailer.

I stuck with the BFGoodrich as I had a good run with KOs on a previous Kimberley Kamper and on the current Karavan and it was also Kimberley's recommended tyre to cope with the 2200 Kg ATM off road. I think the KO tread pattern on the trailers have helped a few times on gravel road bends with reverse cambers (and probably to much speed) had trailer moving off the firm wheel tracks into the soft edges. Keeping steady throttle pulls them back and my heart starts beating again. BFG are claiming the KO2s are 20% tougher sidewalls, 15% more treadlife on road, 2 x longer on Gravel, and 10% more mud traction. KO2s are not offered in 19"https://www.aulro.com/afvb/images/icons/icon13.png. This years GRR trip will quickly test the improved chip resistance etc....

[jwb]

Had to get some tyres in a hurry. Thanks for the comments in this thread it helped me choose the General Grabber AT3. I think they'll do the job.

Last time i saw them at the camping show they were all shod with BFG A/T's as standard

[Bubbledriver]

Hi All,
First post so probably doing this incorrectly.
Background - purchased a Disco 4 2011 with 82K on the clock last December to tug my 21.5' van that will be around 3T when loaded. Was planning to head for the Flinders Ranges late last month so after reviewing these wonderful forums went with the General Grabbers AT3, paid $315 ea for 5. Found an original all weather spare in new condition on Gumtree so took that as the 6th wheel.
I have fitted the Disco with ECB alloy bar, radio, safari snorkel and pioneer rack.
The AT3s were quiet and worked well in the Flinders Ranges. I did lower the pressure slightly while doing some normal good gravel road touring while not towing. Very comfortable.
Two weeks ago I left to go 4 WD with no van in the Vic High Country, joining 6 vehicles from NSW and a Disco 3 from SA. The tracks were rough and on the first day I followed the group in lowering pressure to around 27PSI. Late in the afternoon I shredded a rear tyre, the side wall was destroyed.
I replaced it with the spare AT3 and upped all pressures to 36/42PSI. I arranged for a replacement at Mansfield and had this fitted 2 days later.
Over the remainder of the trip I had two more wall failures on the AT3s, so not very happy with them. No other vehicle had any tyre issues, despite the rough conditions. Came out with no spare available and needing to replace the two AT3s on the roof.
I am considering either looking at the 18" rims as a spare set but if the 19" Maxxis LTs are working out OK then would prefer to go that way.
I don't normally do extreme 4WD, I prefer to tour and then walk but this same group is looking at Binns track for next year and I would like to be set up to join them.
I would like to hear how the Maxxis 19LT's have performed

[dirvine]

I had (still have) Maxis on my old rims. First time I used them in the high country (Mt Margaret) I got a cut on the side wall. I had lowered the pressure to 30. After that I said bugger it and now I never lower the pressure on 4WD tracks. Stays at somewhere between 45-50. Since then no more damage. On good dirt roads (ie Kalgoolie to Winton) I lowered the pressure to 40, but I was towing a caravan. Now have 18" and will follow a more conventional approach of 25-30 in 4WD mode and see what happens. I have done 30,000 kms on them

David,
I have the 19" Maxxis LT on my D4 we traveled through WA last year and went through Gibb river road as well as many other rough roads. We were towing a 18'6" off road van through grr and had no issues with the Maxxis tyres. Basically used the lower tyre pressure on the tyre placard through the bad roads, drove to the conditions and didn't have any issues. I definitely would fit these again, but need to rotate them as the rear tyre has worn because of the Van load.
Cheers
Greg

[Milton477]

Gee, these 19" Maxxis LT's are hard to come by. I have had to pay for 4 to be shipped from Townsville to Brissy so that I can have them fitted next week.

[ozscott]

Maxxis box well.above their retail price. Good kit. Cheers

[Milton477]

& at almost $100 per corner less than the Cooper Zeon LTZ's I currently have they seem like a bargain.

[ATH]

Our new 19” Maxxis 980s are performing well on this trip. No sign of excessive chipping etc. after driving the Skulls Springs Rd and through Warrawagine Station, Muccan Shay Gap and the boreline.
ALanH.

[Hugh Jars]

I bought 5 Maxxis 19” in June to do the Big Red Bash etc. They were readily available at $310 fitted/balanced.
Since then I’ve done 4500km return towing an AOR Quantum (2.5t) plus another 1000 or so around town.

The road from Windorah to the Bash was as rough as guts by the time we drove it. Bulldust to sharp rocks and everything in between. The tyres have performed faultlessly and show very little wear.

At this stage I would get them again. They do make a little noise, but that doesn’t worry me.

[ozscott]

My mate ran Maxxis 980 19 inch to Cape York and the Old Tele Track. Really Impressive. Their depth of tread is some mm less than Duratrac but great value nonetheless.

Cheers

[ATH]

The tyre retailer told me they were noisy but it’s not significant. After having had 3 Deafeners it still seems eerily quiet. 😁

[Milton477]

10k Km since I fitted them, I am finding my set very noisy at 60 km/h. Once at highway speeds though, no issues.

What were you running previously to your Maxxis as a noise comparison? Seems the thread is saying the GG's are quieter. I am currently needing to replace a set of five Cooper LTZ. If you were to do it again would you go General Grabber or Maxxis next time?

[Graeme]

Have a look at the new Pirelli All Terrain Plus - reportedly quiet and has reasonably open tread with full depth voids but not LT rated in 255/55R19.

Your choice is whether you want a true load rated LT construction tyre (maxxis only) or AT non LT. No difference in cost. Quiet is good but things get noisy when u slice a side wall in the middle of nowhere. If remote is your plan don’t compromise. LT all the way. I have grabbers on my 19’s and they are bloody good but would not consider taking them far. Good compromise to replace HT tyres to do a some occasional dirt work. Have 18” rims for all other stuff. If the max is existed prior to my 18’s I’d be all over them. Pity they didn’t do a 255 60 19.
