Can I run 33' M/T on standard GQ LWB without comprising articulation ?
Also , if yes, how does it affect :
1. Braking
2. Steering (would it damage the steering box easiler?)
3. Abaility to climb steep hill (assume the hill is flat slope)
4. descent
5. Does it fit on spare rim at the back ?

Thanks Patrol mate...........

Fitting taller tyres will firstly put your speedo etc out. It will also reduce your acceleration and braking effectiveness. This is what has happened to my 80 series. On the upside, you will increase your ground clearance, and in low range I doubt you'll notice any difference. It's a trade off of one for the other which only you can decide. Safe driving!

keep in mind that the standard 7" rim is not the correct rim size for 33" tyres. You need to go up to an 8"...

Not with 7inch rims, and not without a suspension lift. Well unless you want to hack your guards. Victoria, they wont engineer many 33's the engineer we use will only engineer coopers and bfg muddies, on 8inch rims.

You can get away with 33's on a 2inch suspension lift, but remember you will need to get your car engineered for the 33's. :(

With a 4inch suspension and 2 in body lift, and moving your control arm forward with a spacer 10mm you can get 35's under, no problems.


HTH..

Thanks guys!
I plan to put 33' since I am not a really hardcore 4wder. I just want a little bigger rubber to get the hell out of the deep rut since i guest most of 4wd out there using 35' so 33' will be most suitble to me.
If I run 35' on standard TD42, since it is such a big tyre and heavy, does it further worsen the engine performance of this already sluggish diesel GQ ? Does many people put 35' on natural aspirated TD42 without running turbo?

You didnt mention if your car is Auto or Manual. Auto is not so bad off, although becomes deadly without engine braking on downhills.. (I know)..

To go to 35's you should really do your diff ratios. You will love it on the road, and live in low range off road.

You can tell what diff ratios you have in your car, it is on the compliance plate.
It will say EG**41 meaning 4.1 diffs

If yours comes with 4.1's you should go to 4.3s for 33's to keep it standard gearing, or 4.6's with 35's to keep gearing standard.

Although 33's I didnt bother.

For the Speedo you can get the gears from Nissan to change the speedo back to strd with 33's or 35's. Part is $12, and 1/2 hour work. Its on the outside on the gearbox! Cant be easier.

HTH....

Go with 32's then, you should get them under with no lift, and I dont think they require engineers certificate.

15% wider I think it is.. so depending on the 32's you go with you should be ok.

Try the new MTR's you wont regret it.

32s might still scrub out on max compression but depends on condition of your current suspension and if you plan to upgrade it soon or not.

What state are you in, I may be coaxed into selling my BFG MT's (Not crappy KM's!) 33's on 15x8's reasonable price..

Sorry Truckster, I may not buy any tyre in the next 4-6 months. My truck is absolutely standard except running on 32' BFG and Finer filter.
Thanks a lot ! I really appreciate of your opinion regarding the tyre size. I hope we can keep in touch........cheer!

KM's are ripping sidewalls like cheese..

Lots of reports on 4 internet lists im on, and they are much softer rubber than the old ones, so wont get as many klms if thats a consideration.

OK truckster please Im interested in your info email me if you can, been using the KMs finding them to be wearing very well but no sidewall damage yet. I think they are more a onroad offroad compromise and not a 100% serious offroad tyre however the wet weather bitumen performance is better and noise is down a bit. I bought them for the bush not the road but use them for both, I think a lot more people could use the KMs instead of the ATs and be happier with them than the old MTs Ive got a few converts - if really serious offroading mad scrambling up rocks etc sure use the rest of the serious tyres but everything is a compromise.
I have to laugh when sombody grizzles that their MTs are only speed rated to 160kph geeze cant expect them to do everything. Buy racing tyres. lol
thanks for your reply

Oh and IAMGQ - no! Only 32s for your patrol standard, gearing is nice there too, also better fuel economy hope this debate helps
