I will go with a HWY pattern will be better than a MUD pattern for fuel and braking
Larger tyres play havoc with your braking ability as well
The patrol is designed to run best with gearbox and diff ratios on 265s
so by running 35s I travel further and get great fuel economy NAH wont work

Mic didn't say you'd get better fuel figures

If you are doing a lot of highway kms you could possibly get better fuel economy with bigger tyres.
I know on our Simpson trip, Rossco was getting better mileage than AB and myself. Rossco was on 35s and AB on I on 33s. There are other variables too of course but shows that it is possible.

I get about 1.5-2L better with 285s, second best upgrade I've done.

Only my experience but our old DX4.2TD work ute with as standard 4.1 ratios seemed to get near 50kms per 80L tank further on the 'highway' when I fitted 35" tyres. Unfortunately never calculated stop/start and hilly country usage but in theory should have been worse than the 33" tyres I bought it with.

Pretty keen on the K02's, just wondering what people think about whether the 285's are worth the extra cash over the 265's...local supplier has quoted $400 vs $339.

Will be used for everything from rocks, sand, mud, hills, etc.

On a '09 GU

Cheers fellas

Hi Michael, old thread I know but interested on how the nitro grapplers performed when you had them? Looking at getting a set, have coopers at the moment but don't rate them. Did you have the 295s on sunraysias or stock alloys? Cheers - Westie

I've had a set of them for about 40k and find them to be a great tyre. I've used them on rocks, mud and sand and although you may have to drop a little more in sand (I run 12psi) they've been great for all. Probably only get 50k max out of them but that's fine with me.

Agree with TD... thats why you should change the diff ratios if you "permanently" change tyre size and also seriously contemplate rotor and disc pad selections.
IMHO for touring on formed roads and tracks I would choose the 265's... the extra 10mm of diff clearance won't matter squat really

Funny how people either love or hate Coopers.
I have never had an issue with them and when I change to another brand always end up going back.
I guess it is a 'horses for courses' thing.

Awesome feedback skitz! They seem to have some pretty good reviews and IMO, if I can get 40-50k out of a set I'd be laughing at half the price of the big names. I don't know too many people that are *using* there big namers for distance's greater then that anyway. Cheers bud

I've given coopers a go twice, not gonna get me a third time. First lot had one peel like a retread at 110, was only 15k old and took out rear flare. 2nd lot had side walls break up and blow out again, not that old.

Bfg's I've had good runs with but seeing as I've got 6 to buy this time round, I'm willing to give the nittos a crack even if I can only get half the distance of a bfg. :)

As darren and i found out you cant compair different cars unfortunately.
His gu 4.2t used the same amount of fuel on 35's as my gq 4.2 did on 33's for the murry mouth trip..

From all experiences ive had and been told you roughly loose 1L per 100km of fuel per inch increase..

Im sure im too late but after doing Oodnadatta and the tanami, and talking to blokes fresh off the gibb id say go 31's.
There are no big ruts up here. All the tracks are well maintained now.
Its just corrigations the kill you so tyre pressures are far more important.
