Pro/Cons of wider tyres (245 vs 265 on a stock D2)

[Shakey]

Yes, I know there are plenty of threads on the various tyre sizes etc. for a D2 and the good oil has been helpful, but what I don't know (as somebody who has been 4WDing for less than a year) is what the pros/cons of a slightly wider tyre are.

It seems that a stock D2 can take 245/75/16 or 265/70/16, both seem to be about the same radius (Clifton Scientific Text Services, the Netherlands (http://www.clifton.nl/index.html'tyresizes.html)) of 30.5in which gives me about an extra inch and half lift over the standard 235 BFG Long Trail T/A I currently have but what's the benefit of going with the 265 and potentially having to adjust the steering stops. Should I just go with the 245/75/16 or is it worth the extra hassle?

[Tombie]

245s have less drag so don't hurt highway economy as much...

265s are for people like me who like the wide rubber look... At any cost!

So do they make a difference to stop you sinking into mud/sand too (apart from looking awesome)?

"30.5in which gives me about an extra inch and half lift over the standard". (29 inches)

Dont forget the actual lift is half the diameter or about 3/4 inch in this example

Thanks good point - although I'll round it up to an inch as I'm almost out of tread on my current tyres :)

[walker]

I like wider tyres but in theory narrow tyres are better off road. When you let down you're pressure off road the idea is to get a longer footprint not a winder one. Narrow tyres will give you a longer footprint for the same diameter.

[Graeme]

245s have less drag so don't hurt highway economy as much...An even greater impact on fast gravel roads where fuel consumption is already significantly worse than sealed roads.

[Yorkie]

245/75 is one of the best sizes on the d2 imho, i have gone from 235/70 to245/70 to 245/75 and now 235/85.
the 245/75 felt the best in all driving conditions, the 235 can feel a little skitish, the 245/75 give a nice balance of lift and control. :)

however the extra height offroad for the 235/85 is great. :cool:

[Shakey]

but do 235/8 fit on standard?

[Yorkie]

probably not, a 2in lift works.
:)

[northiam]

My D2 wheels came 255/65/16 at standard 29 inch fyi

[Naviguesser]

About to fit some 265/60/18's.
Sitting in my garage, just got to get them fitted up.
Got them very cheap :)

[ozscott]

I have had stock then 265 and now several sets of different brands of 245/75 ie one size wider but one profile higher....much better all round. .no tramtracking and better for sand.

Cheers

[frostyblue]

Will 265 70 16 rub on a standard disco, currently running 235 70 16 on mine but the coopers will need to be replaced prob another 10,000 k, price i got from nitro where 265 70 16 hankook AT where $240 each, maxxis muddies where $270, guy stated that they wont rub but not sure

Hi, can you let me know when you fit them how they go. I will be looking at a set of new rubber in the not too distant future. I have 18's and I want to go wider than the 245's that are on it.

Happy for you to pm me.

Craig.

[CJT]

I went for a 33x12.5 R18 (approx. 315/60R18) on mine, are they better offroad, who knows, I think they work well and they still drive very well on the highway for a MT tyre.

I have a D2 V8 that is lifted with bar work, roof rack, rear drawers and fridge etc, it still averages 16l/100km on the highway with the 33's.

I think they look good and fill out the guards on mine well, that is the main reason for putting them on.

[Shakey]

Will 235/85 work with a 1inch lift? AFAIK You can lift legally by 50mm in WA above standard tyres so 1 inch lift plus 235/85 over 255/65 is another inch which is 50mm?

TBH I am thoroughly confused by all the tyre options, my research seems to be summarised as follows:


235/85/16 will rub with no lift
235/85/16 may give a slight loss of power


I don't tow and don't have a roo bar. As long as the loss of power isn't too bad, a 1 inch lift will stop rubbing/etc. and with an exhaust upgrade/remap this can be overcome then I'm happy.

[gavinwibrow]

Jakes, I too have standard/no lift. I do have +35 springs on the front, but that just brings me back to std original height.
The best oversize for standard height [255/65 (D = 29.05)] appears to be
255/75 (D = 31.06), but a very hard size to find.
265/75/16's (D = 31.16) do rub, 265/70/16's (D = 30.61) don't
I suspect that I will go with Yorkie at 245/75 (D = 30.47) if my recollections are correct - as the best compromise of available and not too oversize. I do have the six spoke 8" rims, but should not be too wide for the 245/75s

[Shakey]

Thanks - I think that also the 245/75 are the biggest you can get and still stay under the 'tyre diameter must not change my more than 50mm' rule from the Dept of Transport.

I think I'll go with the 245/75 route, no matter how much I stare at the DoT guidelines I can get the 50mm limit to change :)

[gavinwibrow]

But again, if I recall correctly, 50 mm rise actually means theoretically up to 100mm diameter higher tyres (car is only lifting by the radius, not the diameter). However, its the room under the arches and the turning circle bump stops that are the limiting factors meaning needing to keep under 31 diameter.

However, its the room under the arches and the turning circle bump stops that are the limiting factors meaning needing to keep under 31 diameter.

It is a total of 50mm rise, but the following is what the actual rules (http://www.infrastructure.gov.au/roads/vehicle_regulation/bulletin/pdf/NCOP11_Section_LS_Tyres_Suspension_Steering_V2_1Ja n_2011%20v3.pdf) say 'The tyre diameter must not be more than 50mm larger or 26mm smaller than that of any tyre designated by the vehicle manufacturer for that vehicle.' and 255/65/16 is what is on the plate in my car so that immediately rules out 235/85/16 and then:

4.11 LOWERING OR RAISING VEHICLES
None of the codes in VSB 14 allow for the raising of any vehicle where the wheel track has also been reduced. These vehicles are subject to individual approval on a case-by-case basis.

Raising the height of the vehicle may be performed without certification providing the overall increase in vehicle height is not more than 50mm. This may be achieved as a single modification such as the installation of a 50mm lift kit, or by a combination of smaller lifts as described below:


the fitting of body blocks or lift kits (50mm maximum if no other modifications resulting
in a change of vehicle height are performed);
suspension modification, (50mm maximum if no other modifications resulting in a
change of vehicle height are performed);
changes to tyre size (maximum change in tyre size diameter of 50mm); or
a combination of the above that results in a change of vehicle height not exceeding
50mm.

[greg smith]

I have 245-75 AT federals put them on to try as dealer bested all other prices --so far I am really pleased but in the near future will be heading into the cape and rough country so will see just how good they are..Size wise they track well and seem to handle the wet conditions well:D

[Wortho]

A 2in lift will not change what size tyres you can run, if you can run it with a 2in you can run it standard. As the up travel does not change your tyres will still travel up into the guards just as far as before so it's more a matter of how big is your wheel arch, i.e a 33in tyre will not fit in a 32in.
A 235/85/16 will fit no worrys on a standard D2.
Also you don't get a wider footprint when you let you tyres down just a longer one.

[gusthedog]

For those considering a 235/85 I have them and think they are too big. I live in the hills and the loss of power is enough to give me the sh##s. I'll be going back to something like a 245/70 soon which at 14mm over standard should make the speedo accurate and I wont need my tru-speed speedo corrector anymore (people can PM me if they want it :)).

For 99.95% of driving that I will ever do, standard 29's and some driving skill will see me through (hopefully - although my skills are lacking so probably not:(). If I find it too gnarly, I'll go another way. After playing with tyre size and spending heaps of cash I have a car that is less driveable than standard on 32's. But it looks pretty :D

And yes I have a power chip, bigger intercooler etc but I still find the power loss too great - particularly for towing. I think my $ would have been better spent on difflocks.

Just my 25 cents worth (up 20 cents from 5 cents due to inflation):)

Pricey, how much for the speed corrector? PM me if you prefer.

funnily enough i tend to agree but the benefit is when you get offroad and do not get so many bangs and crashes under the car.
245/70 will do for most people, 245/75 for that bit extra. going slow on the highway hills with the camper is a pain but i put up with it for the benefits. :cool:

Technically you would think that would make you two feet higher:D

[Shakey]

235/85/16 need a camel cut to not rub I thought (from all the reading I have done - although I must admit my head is starting to hurt now!).

Anyway, think I am going to go with 245/75 - I'm still new to 4wd so want to give those sort of tracks a try but not trash the car and roof tent. It's not banging so much as the scraping of the diff guards :)

[Shakey]

You're flogging a dead horse!

:)

I'm still slightly confused TBH - is the point that with a lift you get more articulation so even though a larger tyre might rub with no lift it will take a little longer to with a lift, i.e. you have to go over a bigger bump before it catches?

[Tombie]

Get a piece of paper.

Draw a big dot in the middle.
Rule a line across the page through the dot.
"This is the bottom of your vehicle"

Now get a compass. Pin on the dot and swing an arc with a 80mm radius from the line downward.

This is the arc of your suspension.

The line being the limit of "up" travel.

Now lets say std height is 25mm lower than the chassis (line) - rule a parallel line through the arc at 25mm below the existing line. This will be 'static height when stock'

Now to simulate a lift rule a line through the arc (parallel to the others) 10mm lower.

This displays the *static* height with a lift.

If in this example maximum travel down is with the suspension at 45° from horizontal draw this line from the centre dot you first drew.

This section now represents the arc of travel, regardless of static height.

Under load or compression off road the suspension can still move through this entire arc.

So if it rubs at std height, it will with a lift.

[LandyAndy]

Jake.
You are welcome to take my 235/85 D2 for a spin.
I do have issues towing with mine,its overgeared and difficult on hill starts with the boat.
I will be changing the transfercase gearing to Defender ratio to bring it back to standard gearing.
Go the 235/85 tyres BRILLIANT off road.
Mine is manual,your auto will be less effected with the over gearing.Could even put some 235/85 rims tyres on yours for a test drive if you wanted to mess around.PM me if I dont see this thread again.

OK so final (I hope) questions around this.

Having read all the ADR/NCOP/documents I'm getting a serious case of brain ache, is it actually legally possible to put 235/85/16 on a D2 as the tyre diameter is more than 50mm greater from a factory fitted tyre option?

Or is it the case that you need to get an engineer sign off for that (I'm in WA), and if that's the case I might as well chuck a 2inch lift on at the same time and get the whole lot done?

Is engineering sign off difficult/expensive?

[walker]

"Legally" you cannot fit 235/85-16 (32") tyres on a D2 without engineering.

However, I really don't know why everyone gets so uptight about tyres and engineering. When has anyone heard of someone getting pinged for running 32"tyres. I know I never have. I was pulled over for a random RWC check in the D2 running 32" MTR's and it passed without a problem. I was pulled over 2 weeks ago for a RBC and at the same time they had a good look around the vehicle. I was running 285/75-16 (33").

Just run the tyres and don't worry about it

Hi
No it is not legal. Tyre size is max 50mm. You have to get it engineered. The lift up to 2 inches can be done without approval, over that requires engineering.
The form can be downloaded from the dot website, pages of crap to fill out, send off and wait for reply. This will give you preapproval, you then do mods and take to approved engineer who will charge you lots of money to do a brake and possibly a swerve test, about $1600 somewhere if both are required.
Pm me and we can chat in person if you want.

Because our coppers and dot over here are very anal. Last I heard they weren't doing any swerve testing because they rolled a land cruiser.

And if you are not legal, if you crash and the crash can be attributed to your illegal mods, no insurance, and possibly criminally responsible if someone is hurt...it's a very good reason to be legal.

Thanks Kev - she the engineering is so much if it was a few hundred bucks I'd defo go for it but seems a bit steep to add on top of a set of tyres and a lift!

Will drop you a PM - don't suppose anybody has suggestions of a land rover friendly engineer in Perth?

[TD50WA]

Unfortunately the dot has a list of approved engineers, so choice is limited, but I'm sure there will be one who is a lr fan.....:D

[walker]

Wow. you guys really do get stiffed over there. Anal cops and huge costs for engineering, I am feeling good here in Melbourne :D

I converted a Range Rover into a ute, added 4" lift, 33" tyres and a larger engine and the entire engineering cost me $800.

Almost right walker, I think you had a typo in that first sentence - I think you meant everything rather than engineering ;)

[Tombie]

Walker...

Plenty get done in SA for oversize tyres..

And over GVM too.

They weigh random 4x4s travelling SA now..

But the worst is not the Cops.. It's the Insurance if you have an accident that matters!!! An assessor doing his job could refuse to pay if you back end someone because the brake effectiveness is reduced.

If a fatality is involved it gets damn ugly.

Risk assess at your discretion.

[Shakey]

Well in the end this is a pretty easy decision, and also making me think about a career change :) Just rang up one of the engineers in Perth

$1,000 for a 3 second line change test to put 235/85/16s on a D2 (Change lane at 100km/h in 70m).

So I don't think I'll go through the time/effort and hassle TBH! The guy on the phone was really helpful - he said the DOT had failed somebody for being 2mm over the diameter so for the sake of insurance I'm just not prepared to risk it.

[Yorkie]

nsw law meant 245/70 was the biggest you can go (within 25mm??) so maybe stick with them, still a good size and keeps your morals in tact. :D

[mrapocalypse]

265/75/16 and why not get a 2" lift..... ? Great mod!

[chuck]

One of the benefits of the wider tyres has not been mentioned.

The wider tyres help keep the body off the wall.

Wider tyres will also help on sand and snow.

I used to run 265 x 75 x 16's on Landrover rims.

IMHO the 265's are a great size on a D2.

Some of the good 4x4 places will already have the engineering done for you if you buy their product (e.g. Les Richmond).

[ozscott]

If you are limited to say 31 inch then achieving that via an increase in profile size will give more benefits on sand than via width increase and stock profile.

Has yours got ACE??? Will pass no problems even with lift;););););).

[walker]

And here we go again. :p

Yes narrow tyres at a certain diameter will give you a longer footprint than wider tyres at same diameter, which is what you are after when you deflate tyres.

However, as others have stated, the 265 width is a great size on the D2 and I think what they should have had from the start. Most modern 4wd's now come with 265 tyres as standard. They track a lot better and there are a lot more tyres to choose from.

No it doesn't - has SLS, but for $1,000 I'm not sure I can justify the cost!

Yes. I had 265/70/16 in several brands and have now had 245/75/16 in several brands and mine tracks better, tows better and offroads better in the later size. Now if I had a lift I would probably go 265/75/16.

I wonder if he would do an AULRO group discount?

I'd be interested..........

... I think a lot of that cost is to hire a track/driver for the swerve test so perhaps if they could all be done at once it might well make a difference.

I have 245/75/15 on mine, with no issues and without any lift. Good on road also, but it 'eats' a couple of HP from our Td5. A remap it is recommended for the best driveability.

/15 or /16?

Did your fuel economy go down too?

:oops2: Sorry they are BFG A/T on 245/75/16 or 30,5" . The fuel economy remains the same, practically: 10 to 12L/100km in my case, re-mapped to a Stage2 from TD5inside.

[elshano]

just chucked a set of coopers at3 in 245/75/16 on the disco, got em for $300 a corner. Spare fits on the back, just.

Previous tyres were goodyear wrangler at-r in 235/70, they were actually pretty good tyres, didn't manage to puncture one in about 3 years.

Will give the coopers a good workout this weekend and report back.

Where in Perth did you get them that cheap?

See you on Sunday's trip.

[elshano]

Yeah looking forward to it!
My cousin's workshop is just over the road from a tyrepower so they have a pretty good relationship with them. He wasn't thrilled about the price it must be said :D

Just a bit more info for you to make it harder to pick.

I just put some Mickey Thompsons in 245x70x16's on the d2, it's got a 1inch lift and no issues at all. Just on $300 each.

Thats about as big as I wanted to risk and she still drives like a dream, no power loss noticed, though it's got a DP chip in it.

The D1 has STT's 265x75x16's with 30mm spacers and even with 60mm of lift it rubbed pretty bad at the back till the camel cut was done.
It changed the performance a bit but the 4.6 can hack it.

You getting fresh rubber for this weekend?

I was offered 365 a corner for 235/85/16 coopers but I need to do a 2 inch lift too and won't get that done on Saturday (mainly as I don't have shocks or springs - just spacers for sls)

I have ordered and paid for front springs and 4 shocks but I haven't ordered the SLS spacers yet. Can I borrow yours (jokes). Together we will have a lifted disco.

LOL - good luck with the lift. First major mod (after snorkel) to mine :)

Ok. I didn't give you the full story. It has unknown springs in the rear. They are of unknown lift but from my measurements, I think they are about plus 1 inch. So with what's coming, I'll be in action. SLS resurrection is next in order. All the SLS running gear is still in place but the compressor has had the possum.


Next will be a winch and then a snorkel before next wet season


Anyway. I think we have sidetracked this thread enough. Back to tyres.

Were they ST's or STT's? I paid around $400 for the STT's early last year.

Patience sucks doesn't it, but it pays to make sure you get all your suspension sorted as you'll end up chewing bits of tyre out on your guards- Speaking from experience. :confused:

The ST Maxx - yeah it does suck having to wait, but with those prices it's probably worth it :)

Remember on the old surf we brought when we first arrived in Aus with 35inch muddies scraped whenever you tried to go round a sharp corner!

[OneGoat]

Thats a pretty good price for the ST Max's but still not cheap enough to scrub them up.
I'm waiting for some parts to come from England and my patience is already wearing thin, only ordered them on Wednesday :angel: so yep, know what you mean.

Well, I've been down to talk to Lyal at Custom Tyrepower in Kenwick, who has been recommended several times here. Lovely older gentleman.

I'm staying stock height on my D2a with 8 inch rims but want a tyre lift and he suggested Kumho KL61 AT at 265 70 16 for D = 30.6 inches / 777 mm - the largest wont rub size - at $220 each including fitting/balance and wheel alignment as what he would put on his car for my parameters of heavy towing, very occassional rock climbing and WA sand (I told him I didn't want muddies). The only thing I forgot to specify was no uni-directional as I want 6 tyres and to be able to swap sides as well as front to rear. He recommended these more that the 245 75 16 for D = 30.5 options with my 8 inch rims.
ROAD VENTURE SAT KL61 | (http://www.kumho.com.au/blog/products/road-venture-sat-kl61/)

Interstingly he said Rio Tinto still specify Coopers for their minesites, which may not accord with some comments here.

[Roberto]

I like the look of the 245 75 16s with a 2" lift. The tyre fills the wheel well nicely. The D2 looks as if it is perfectly balanced with the 2" lift. Un lifted cars look somehow disproportionate. But a lift without bigger tyres looks bad too. I also favour the narrower 245 over the 265 - wide tyres look a bit like they belong on a hot hilux rather than a serious off road tourer. The 245 STs and STTs have both performed admirably in desert conditions (dunes and tracks).

That is interesting, Ive had my Cooper STT's on for just on 60,000 ks and they've been all over the Pilbarra, with numerous trips from Meekatharra to Wiluna ( About as rough as it gets), about 6 months straight on a new camp at Area C and a couple of trips tp Pumnu ( About 150 Ks East of Telfer and a whole host of other mine and construction sites. I'd estimate somewhere between 17-18000 was on dirt roads.

Never had a flat and still have about 9mm of tread.

Can't say that about the tyres we had on some of the utes (see picture)
I'm not sure what they were but the 3 letters I can see in the photo are DUE. These done about 12000 ks from new to kaput :confused:

[joel0407]

I'm pretty keen to give BF Goodrich MT a try next set. I currently have Cooper S/T the old ones not the MAXX. They aren't that good in mud, as I found out yesterday.

I dont want anything too open spaced as I know it will effect fuel economy. I have run Mick T MTZ on a 75 Series ute and they added another 2 L / 100km.

Happy Days.

Bumping this one again with an option I haven't seen yet.

From what I've seen the 235's are skittish at speed (which I'm definitely experiencing on my disco to a point at times of it being dangerous) - 245's are a great improvement and 265's run the risk of rubbing on standard height.

Looking at the BFG Muddies they have a 255/70/16 option - has anyone had any experience with those?

Keen on thoughts - I need to re-shoe this thing this week before heading to Melbourne on Thursday night.

Cheers,

Michael.

I went with Toyo MTs in 245/75 - they are a big 245 by diameter and seem to give the best of both worlds IMHO.

[Yorkie]

My local Bridgestone dealer can get the new muddies in 245/70/16
Lt, $214ea, that's my next set. :cool:

Yep...245/75 is the best size for off road on an unlifted d2 in my opinion. Always go higher profile versus width.

[ozscott]

265/75/16 and why not get a 2" lift..... ? Great mod!


https://www.aulro.com/afvb/images/imported/2013/09/1689.jpg (http://s518.photobucket.com/user/NomadCamera/media/Disco232.jpg.html)

Wouldn't that be considerably over the 50mm total lift allowed? ?

Cheers

[northiam]

In NSW it seems they (RMS) are still only allowing a 15mm larger tyre/wheel combo than standard. Any word if this is likely to change like vic and queensland?

You should go to the Regs but here is Mickey Thompson's website referring to a 2 inch increase in Qld.

From what I've seen the 235's are skittish at speed (which I'm definitely experiencing on my disco to a point at times of it being dangerous)

I've been running 235/85r16 Hankook MT-03's for a few years now and never had that "skittish" feeling.
If anything, I way prefer them over the "fatter" tyres - cut through mud better, deflate to a better footprint, and lifts my diff off so I can get up and down those urban kerbs better!

There's a reason why the G4 D2's used the skinny 225/75r16 MT/R.....

My 2c anyway! :cool:

[infrno]

Ok - due to time constraints I've gone with the BFG MT's... Toyo's were three weeks away so that counted them out, Cooper's are apparently not doing the STT's any more? The Bridgestones are also a few weeks away and, at the moment my local TyrePower are doing them for $340 / corner (September special apparently) from just on $400 - so destiny pointed me there. Being fitted up Wed, and we're off to Melb on Thursday night - hopefully with a much better behaved car.

I'm not planning on keeping this one past the next 12 months at best (looking at newer disco / RRS depending on coin at the time), so lifting etc really isn't in my radar to justify the awesomeness of the fatter tyres as much as I love that look.

Cheers for the input guys - it's always good to look at options!

[Naviguesser]

Finally fitted up the 265/60-18 Yokahamas.
They fit fine on stock suspension, no obvious rubbing even on full lock.
Still have the front ES spoiler fitted at the moment,.

Only issue is that the speedo is about 5% fast now (it was spot on before).

[R Miller]

Have any of you tried Mickey Thompson ATZ 4 Ribs in 265/75R16 on a unlifted D2?
