D3 18" off road tyres?

[Disco3]

Hi all. had my disco 3 for almost 2 years now and looking to change my 18" factory rubber (goodyear wranger HPs) for something that can bite in the mud - HOWEVER - I'm told by my local tyre place that the only replacement is a goodyear wranger HP!!!!!!. surely Coopers or someone is doing a replacement? Im hoping I dont have to run two sets of rims! Has anyone got a spare set of 17" D3 rims?

Calling Stevo...

[PCH]

General do an General Grabber AT2 in 255/60/18"

Yokohama have an AT in a GEOLANDAR A/TS 265/60/18"

No MT's in 18" to fit.

[stevo68]

Calling Stevo... Someone rang :D. Yes mate, as Chris has said there is...and I have 18 inch General Grabber AT2's in a 255/55/18, plus you can get in a 255/60/18. BF Goodrich have bought out a BFG265/65/18 AT and I am waiting to find out if the new MT will fit. Another D3 owner has Mickey Thompson ATZ 275/65-18, with a slight rub. Here are some pics of mine:

[Disco3]

Thanks all. Ive called a few tyre places and everyone is telling me that no-one carries, or is able to bring in Generals. In fact one place told me they were banned from being imported!? I told them they were wrong as Ive seen 4wd's with them on ... but in the end I got no-where. Anyway Stevo - where did you get your AT2's from?
cheers Lance

[stevo68]

Hey Lance,

I got them through my local tyre bloke, who I think from memory got them from WA as the local Brisbane agent was out of them. Here go to this site they will be able to point you to there distributors....Dynamic 4x4, Simex 4x4, Sime 4x4, General tire, Dynamic Wheels, Sime, Grabber, Extreme Trekker, Wheels (http://www.simex4x4.com/html/s01_home/home.asp'dsb=13),

let me know how you go,

Regards

Stevo

[Disco3]

problem solved! Thanks Stevo. One last question then I'll stop bugging you. I presume these things work well - sound OK on the road, work well in the muck / snow, live a little longer than the wrangers? Cheers Lance

Cheers Lance Mate, they are still a little low profile for my liking with the 255/55, but then again depends on what you are doing. In terms of comparing against wranglers, a huge improvement off road, better grip and confidence. Can't hear on the road, mind you hard to hear anything once the windows are up, fuel economy on par, a decent all rounder in my books,

Hi Stevo,

Just changing the subject a bit. I noticed in your photos you had a UHF radio. Can you tell me where you have the arial.

Steveo,
Are u running 18's as yours is an HSE, so originally u would of had 19"s.
You keep saying u are running 255/55's. (255/55/19-Originally)
Just want to double check as General make the tyres for both the Sport & D3 in 18".
Sport is 255/55/18
D3 is 255/60/18 which is slightly higher...:)...i did say slightly..;)
If u are running 255/55's (18)then they are the wrong size! for the D3...

[bigmac]

Hi Disco3
I have General Grabber AT2 255/60/18 on mine and have found them to be good
I am getting a bit of road noise now but they have done nearly 40ks.
Found them good off road an on.
I got them from DOG TYRED at Kallangur

Bigmac

[Disco3]

thanks BigMac. My current wranlgers are almost dead at 25k's, so 40k is great. User surveys on the AT2s look great (http://www.tirerack.com/tires/surveyresults/surveydisplay.jsp'type=ORAT), so I think I'll put my order in for them. Thanks all for the help. Cheers Lance

[chuck]

I have been doing a fair bit of research on tyres for 18's lately.
I have come up with the following options;
1. Mickey Thompson ATZ's in 275 x 65 x 18 = 32"
2. BF Goodrich ATKO's in 265 X 65 x 18 = 31.5"
3. Goodyar Wrangler Silent Armour in 265 X 60 x 18 = 30.5"
4. General Grabber AT2 in 255 x 65 x 60 = 30.04"

All of the above tyres will fit however the Mickeys will rub ever so slightly.
comment received on the D2au site indicates the Mickey's to be the best tyre but boy are they expensive - I priced them for $430ea.
Others have also reccomended the Silent Armours & the Generals.

In addition Mickey Thompson are about to release a 4 rib more aggressive version of the ATZ in 275 x 70 x 18 = 33.15" these may not fit, however they are nearly as aggressive as a mud terrain.

If you have 19" rims you can get Goodyear Wrangler MTR's in 255 x 55 x 19 = 30".

To my knowledge there are no mud terrains in 18" that will fit landrover discoveries without huge lifts & body cutting.

hope this helps

Hey mate, I just have a hand held for now for convoy trips that I go on with the club. However my rear bar has a spot to put an aerial once I get an incar UHF radio.

The good news is that finally tyres are coming out, it has been a wait since having mine from Dec 05 :D. WHen the Grabbers have seen there term I will be looking at either the BFG's or Mickey Thompsons, simply as they have a higher profile,

Actually Stevo, don't mean to rain on your parade (or highway in case the traffic stops:p), but...

In some states (such as here in WA) the 255/55/18 is illegal for two reasons:
1. the overall diameter is 25mm less than standard and the law allows for only a 15mm difference; and
2. The load index is only 109 and the D3 requires a 110 or above.

The 255/60/18 Grabber is Ok I believe.

Regards

Stevo

:p to you too Jamo :)

[Jamo]

The 255 is the width in mm.
The 55 is the percentage of the width that the sidewall height is.

ie 55% of 255 is 140.25mm for each sidewall = 280.5mm total
18" rim at 25.4mm per inch = 457.2mm
thus the total diameter is 738mm.

Of course this will vary with tyre pressure and tread wear etc.

The nominal diameter for the 255/60R18 is 763mm.

I doubt having the 255/55's is going to cause any real trouble though. I've never had either the police or an insurance company check anything other than tread depth.

I don't doubt that they advertised the tyres a suitable. I still get salespeople trying to tell me anything that fit's a D2 will fit a D3.:eek:

[Disco3]

I have a $420 question. I've decided on buying 4 of the Goodyear Wrangler Silent Armours (265 X 60 x 18 - best quote I have is around $420 each), and have been told by two tyre places that I dont need to change my spare (factory goodyear 255/60/18) as its within the 15mm tolerance (so long as I dont keep it on for more than a few months), BUT 2 other tyre places have said my disco will fall apart immediately if I use the spare with the 255 on. If I do get a flat I would obviously change ASAP (granted that it may be a few hundred k's), but what do you think - is there a risk or are these tyre places really full of crap?

[Tote]

I wouldnt think there would be a problem 15mm would surely not be enough to trigger traction control or cause the centre diff to lock. I can't think of any other ill effects other than compromised handling but you would take that into account if driving on a spare anyway.
Regards,
Tote

[bigmac]

You must check that they are both load rated and speed rated or else
the insurance mobs could wipe you if you have an accident.
I know when I was looking last year that the only ones that were rated for
both were the General Grabbers that I got.
Hope that has changed by now though as it would be good to have a bigger
choice.

Mate all I know is at one stage as I only had 4 of the 18's and the 19 was a spare until I could get the other 18. Was told same diameter yada yada, should be okay...NOT. Of course I ripped one of the 18's and had to put on the 19, TC kept kicking in on way home when I went around bends. As soon as I was able to put the 18 back on, prob went away.

The load rating's more important than the speed rating.

WA law allows you to use a lower speed rating provided the tyres are used well within the applicable rating.

[muppo]

I'm in this same position with new tyre choice. I'm going away for three weeks this Saturday so the new tyres will be fitted this week but I've been told by my tyre bloke to wait untill Tuesday as his reps are getting back to him about more brand choices.
These are what I've found to fit so far,
255/60/18 GGabbers AT2 passenger
265/60/18 Yokohama G012 ATS passenger. I had the G011 A/T on a Pajero a few years back and think that they are one of the best alround tyres I've had but they have a poor wear rate.
265/60/18 Goodyear Silent Armour passenger (they claim they are the strongest A/T on the market) I have these on my work Hilux and are impressed but only done a few thousand on them.
265/60/18LT BFG A/T not listed anywhere but I'm told they exist and are available.
265/60/18LT Cooper ATR again not listed anywhere but are available. I had these tyres on my last car a Landcruiser 100 V8 and the rear tyres got tore to shreads, whole lugs missing and was told by the Coopers rep when I wanted them replaced that I should have fitted ST's because of the weight of the car, and with Vic High Country terrain the ATR can't handle it. They where 265/70/17LT so I bought some 265/75/16LT STC's and rims and never had a problem again. The D3 weighs more than a Sahara V8 so ATRs will be destroyed even quicker. I would never buy them again for offroad but they where good road tyres.

The 265/60/18 tyre size only increases the speedo reading by 1.3klms. I'll let you all know what I find out and finally which one I choose.

[Disco3]

Been told the Goodyear Silent Armour have the wrong load rating so cant be used on a disco- have been told that the Cooper HT Plus are the go and are one of the longest lasting tyres on the market. Anyone else used cooper HT plus?

Running one odd size tyre can cause all sorts of dramas on the D3. We chased strange wheel speed faults for ages on one then realised one of the tyres was a different profile to the other 3.

Well the Grabber's got the nod in the end for a few reasons, and those being that no other tyre had the 112h load and speed rating and the same size 255/60/18. The BFG's turned out to be Long Trails not A/Ts, Yokos under rated and way over priced. Goodyear's are expensive and under rated too. Coopers are perfect besides size but my past dramas have lead me away from them.

Now for the good and the bad about the Grabbers.
Good first, their handling in the dry is top notch, as for the wet well it doesn't rain in the sth east anymore it seems so I can't say yet how good they are.
The have a much stiffer side wall than the stock wranglers so the ride fells much more controlled and stable. The air suspension seems to work better less wallow and pitch, I read else where that the 19" wheels give a better ride too so maybe the stiffer sidewalls have something to do with it.
Only done 3k so far but wear looks good, the shoulders still look new.

Now the bad, Noise noise noise, what can I say. I read multiple times about how quiet they are but really they are noisey with a drown and rumble at low speeds but at highway speed there is little noise. If I didn't do much off roading I'd buy the Cooper ATR's instead they are very quiet. I think there is more steering rack shake but this could be a dodgy rack or just because they are are heavier and stronger tyres than the stock wranglers.

In the end I'll probably look at a different tyre and rim combo next time and put on a quiet tyre for everyday use.

I also found as with my Pajero you need to check the 4 wheel alignment more often or the inside of the tyres will scrub out.

Prices
Yokos $430
Silent Armour $430
Coopers $380
BFG $N/A
Grabbers $335

Scouse, BigJon,
We have had 2 vehicles(TDV6 HSE) arrive from factory with the same rim as a Sport TDV6 rim....But as u guys know the tyre profile size is different.:eek:
One we had problems with lights, warnings etc & we could not recalibrate the suspension until we realized what the problem was..So much time wasted for nothing...:mad:
All else who has a D3 when ordering new tyres just make sure the tyres are the same size as each other-D3 255/60/18(factory size)

Cheers.

How had your old tyres worn, did they show any signs of wear through mis-alignment? Just a thought, because if your tracking is out that would make the tyres noisier. As you will know the D3 is set up like a car with adjustable cams, everything is adjustable on both axles for toe, camber, etc.

Interesting as I find the Grabbers fine, in fact noise being neglible. Windows up don't hear a thing, windows down, at speed no problems either,

Like Jon said, the wheel alighment can affect noise levels.

Mine made a racket when the alignment was out and quietened right down when it was fixed.

[baggy17]

Some feed back on the Yokohama Geolander A/TS 265/60/18" - I've had them on since mid-Oct'07and very happy with them. As quiet as the Wranglers, little more roll on tight corners then the Wranglers (on the tar), work well in the dirt, have yet to give them a good run in the mud, wearing well (15,000k's and lots to go - certainly better then the OEM's).

The insides had worn uneven due to poor wheel alignment but that was rectified when the new tyres where fitted.

Was the alignment done by a main dealer or a tyre shop?

I ask because the air sprung D3's have to be set to a specific height before alignment is carried out for it to be done correctly. The required height is non user selectable and has to be done with Test Book (The LR diagnostic computer).

My dealer did mine just before I got new tyres fitted and it only cost $90 for the full alignment. These cars are also complex to set up and is best done by someone who has done a few before.

A further comment on 18" tyres for OR work.
I fitted a set of 18" AT tyres and travelled over 3000 kms offroad and 2000 kms on the black stuff (heavily loaded). On getting back to the coast I had the tyres examined by the manufacturer. Following are the comments from their technical experts.



Our Tyre engineer has found the following;

What has occured is called, swelling of the tread. It occurs due to a signifcant difference in temperature between the tread and sidewall. caused by low pressure usage over an extended time. it is also evident near the bead area of the tyre.

Our engineer has advised this is not uncommon in H, V and W rated tyres where the tyre is manufactured to meet very high speed requirements. This reduces its offroad ability, as the offroad ability is compromised to meet the high speed rating.

It is also magnified by the fact this tyre is of low profile design, so the sidewall height is significantly less than a normal LT or offroad style tyre. When used at low pressure heat build up will occur faster than a taller sidewall tyre.


I am not having a go at any tyre manufacturer as this will apply on all. All this highlights that if you intend to use your D3 with 18" and 19" tyres in long distance low pressure touring (i.e. the desert) you will experience premature failures. I will review my tyre options and will probably purchase a set of 17"s for my desert and outback touring. For short distance offroading I don't believe that there are any issues.

It was done at a tyre joint so this maybe why the tyres are noisey! I'll get the dealer to do at wheel alignment and i'll post the results.

[Desert Traveller]

Southside use Bob Jane at Coorparoo for their alignments.

[D3Jon]

Barbagallo's do it for $90. They have their own tyre shop next door and do D3's all the time.

Southern Land Rover previously sent it to Bob Janes who unfortunately didn't get it quite right :rolleyes:

I didn't get the tyres from Barbo's though, because although reasonably competitive for a main dealer, they aren't the cheapest.

18" tyres are very hard to get in the outback (so I've been told) if you have a problem, just wondering if anyone has fitted 17" wheels or better still 16" as I'm up for a new set of tyres (40k on the wranglers) and am intending doing the big one next year in our 2006 D3 TDV6 SE.

Have seen a set of 17" that will do the job, but after reading this thread will be asking a few more questions of the dealer before proceeding.

[Scouse]

17"s are a common fitment. 16"s will not fit due to the size of the brakes.

The 17"s are also available as an aftermarket wheel too.

Factory 17" D3 rims turn up on Ebay and in the local free ads papers now and then, because coil sprung "S" spec owners sometimes upgrade their standard 17" rims for something a bit more bling (like 22" chrome jobbies :rolleyes::rolleyes: :D).

Keep a keen eye open and you can bag a bargain, it's also worth talking to your local dealer, because they may sometimes have new 17" rims from an owner whose upgraded.

I just pulled out the invoice from when I had mine done last November by one of the main dealers here in Perth and it cost $87 +GST, so $230 sounds a bit pricey to me.:eek:

Bear in mind thought that my dealer sets the suspension height and then sends it next door to their "in-house" tyre shop. Maybe your dealer does the lot with LR mechanics at LR rates!

Just read about the TSB fix for alignment and geometry setting on Disco3.co.uk, maybe this is my problem as the original tyres did scrub out the insides before 25k? I will speak to the dealer on Monday.

Up to a certain VIN number (MY 2005 and some early 2006 models) they can wear out the inside edges of the rear tyres early due to suspension bush settlement and LR getting their initial sums wrong (bless 'em :D)

Basically, all manufactures set the vehicle geometry at the factory allowing for some settlement in the rubber bushes over the first few months of the vehicles life. Land Rover initially got it wrong and there is a TSB (Technical Service Bulletin) which covers this, so they will do an alignment for free under warranty and also contribute towards the cost of tyres due to excessive tyre wear in some cases.

There's loads of info about this on DISCO3.CO.UK - Dedicated to Discovery 3 and LR3 Owners and Enthusiasts (http://www.disco3.co.uk).

I had 2 alignments done under warranty, mainly 'cos I'm a fussy bugger, and thankfully my original set of tyres ended up lasting 43,000 Kms. They would have shredded the inside edges on the rears in less than 10K though if I hadn't noticed the abnormal wear early on, and quoted the relevant TSB number to my dealer.

Just had a quick look: check here for some more info:

Thanks both.

LRA air freighted 2 new Wranglers from the USA because of this issue. My D3 was unroadworthy.
Southside and LRA are very good with warranty issues compared to other manufacturers and dealers.:D

I had the alignment done yesterday at the dealers and it was out by heaps in the rear and a little in the front left. The tyres are much quieter than before but still louder than the Goodyear Wrigglers. It cost $183 and took 2.5hrs.

[jik22]

Well the Grabber's got the nod in the end for a few reasons, and those being that no other tyre had the 112h load and speed rating and the same size 255/60/18.

Prices
Yokos $430
Silent Armour $430
Coopers $380
BFG $N/A
Grabbers $335

Can I ask where you got these prices from? Best I'm getting over here today is $422 + $20 fit/balance from one place and $475 fitted/balanced from the other.

Sub-let wheel alignment cost at 24k dealer service in Sydney's West was $80 for me last Friday...and yup...a little scrubbing on inside of fronts. Mine is Dec 06 build TDV6 "S" compliance 2/07. Allegedly "normal".

Thanks. In the end, I booked it in with the local dealer to have 5 Generals put on with it's 24k service. $455 fitted, but using the dealer means I'll get their Leaseplan discount applied and they can sort the alingment out as well (Which was quoted at $128, so that seems to have gone up too!).

Hi All

I had one of my managers have a quick look at this today and the most important thing about tyres is the load rating (speed rating is not really a concern here as we no longer have unlimited road speeds, that I know of maybe NT still does? but...), on the bottom right corner of the drivers door is the rating plate, the min load rating that the SE (I assume it will be the same across the S and HSE, in the tyre books it is) is legally allowed to use is 109T which means the tyre options are

OE Size 255/60R18 112H
Options 265/60R18 109T

(Discovery 3 SE TDV6, 4.0 V6, 4.4 V8)

Which means all of the major brands should have a tyre to match either one of these sizes. Cooper, Dunlop, Conti, Pirelli, Goodyear etc (note the Goodyear you can also get in an ATR Silent Armour)

Cheers

Just a quick question guys.

Is 265/**/** the widest you can fit on a D3? And if they do rub, where about?

[chuck]

No - you can fit a 285 x 60 x 18.

Some of the guys have these in Cooper LTZ's

Regards

Chuck

[lovemeLr3]

I like the look of these but am a bit nervous about how the extra width will be when deflated to around 20psi as there is not much clearance from the front shocks. Has anyone tried this out?

[CaverD3]

I don't think you can get them in the spare wheel space without deflating.

[TDV6]

And even though they have LT in the tyre designation LTZ they are only listed as passenger construction not Light Truck, but their load rating is the highest I have seen available for the D3 at 120 and a speed of S which translates to 1400kg and 180km/hr, well worth considering if and when QLD changes to the national code allowing 50mm increase in tyre diameter not the measily 15mm at present.

Hi chuck, has anyone had any problems with rubbing ? given the extra width. They only just fit fully inflated how are they with reduced pressures

[Forest]

I believe there is rubbing on certain models, (08 onwards I seem to remember) and beware the rear air conditioning pipes. However, I think the slight rubbing is more cosmetic then mechanically damaging.

[techchook]

I was looking at the Mickey Thompson ATZ as replacements for the well worn after 25,000k's goodyears - yes they saved us once this year so they remained good until now... reading through this thread has provided as much help as confusion, but no-one has mentioned using ***/65R18 as yet - forgive me if i'm wrong but this is an extra 25mm of clearance. I thought i'd ask the Q to get smarter peoples opinions in this area.

18" LT275/65R18
LOAD & SPEED 123R
OVERALL DIAMETER (MM) 815

BTW, if you are in need of 18" rubber while you are near the Flinders Ranges, be careful of who you deal with, $490 for a single tyre (Continental ContiCrossContact UHP - apparently not a bad tyre but not what I was looking to pay) seems on the obscene side of unreasonable but was all he stocked in that size... It might pay to phone around prior to departing to see where you can get rubber from before you go. I'm still smarting from the transaction...

2nd question that has popped up after reading this thread... will the tread pattern play havoc with the TC or any other system if i needed to run on it with the remaining 3 Goodyears?

The price isn't a million miles off normal. 18" is not a cheap size.

I would never mix tyres on the same axle as you can get unpredictable braking. Front to rear mixes are better if needs must, but be sure the (actual) sizes are very close. This can still lead to screwy handling so it's not ideal.

Put the new tyre on your spare and run on 4 goodyears until you can get them to match.

Cheers, Steve

[Forest]

Yep, wait till you replace 4 tyres, THEN you will be crying:eek:. You won't get that much change out of $2000 regardless of the tyre you buy. In Melbourne, the Goodyears were $480 a tyre last time I looked. :(

[CaverD3]

Alto service in sydney had some GGATs at $320 a while ago I think they still have some left. Speak with Gary 02 99013712.

[Dingmark Jim]

Don't feel too bad. Saturday I had to buy a new 19" MTR and the "trade price" was $720.:eek: This makes the V8's fuel consumption seem pretty reasonable compared to tyres.

[CaverD3]

:o Thats almost as much as the X5's tyres.

Hi Guys, just picked up on the thread.

I have a set of LTZs on my MY08. Have done around 17,000 since fitting. I have not experienced any rubbing front or rear at any ride height setting. You will have problems mounting in spare wheel well, so I ended up fitting a rear wheel carrier.

The LTZs have a diameter of 799mm which is about as large as you can go without rubbing. If you place your hand over the top of the front tyre and fit your finger between the tyre wall and the wishbone knuckle you will see you have only a small clearance (approx 10mm at best), so would not want to go wider. Would be great if they made a 265/65/18 size - a little more sidewall and a little less width, perfect.

Cheers,

[tarmac]

Cooper in australia have just got stock of the ATR in 265/60r18
this one has been a long time coming.....
i will give them a workout this weekend.

Great information from you all, thanks, but I was just wondering how my insurance company will go if I have a claim and they see that the General's tyres that I have fitted don't comply with the V rating required.

Anyone tested their Insurance companies to put it on paper to say that they approve of the the General Grabber being fitted to the D3/4 ?

Insurance companies have the 'final say' when paying out on a claim, spose its something that we don't always think about until its mentioned.

[Graeme]

The courts have the final say. If an insurance company tries to get out of paying a claim because they say something is illegal and its not, then they have to pay.

In WA, for a 4WD your tyre must be rated to the manufacturer's speed rating OR to 140kph, whichever is the LESSER. Not sure about Victoria - you have funny tyre/wheel regs over there!

NSW is the same.
