Hi ramp,

I had 285/75/r16's BFG MT's on my 2.8lt TDI GU patrol with standard springs before I sold it - worked quite well although I must add that we didn't do any super hard stuff so I never really tested the extremes of articulation with them, there seemed to be plenty of clearance though.

Cheers,

Luke.

I might add also that I put the MT's on the day after I bought the car so I can't really compare the 2.8TDI's performance with them to the standard tyres as I only had the standard rubber on for about 24hrs :-).

What suspension do you have? Std or lifted? this will determine what tires will fit without hassles.

Steve Roly had 36's Swampers on his 3.0 GU with 3inch suspension lift.....

Extra Load on the 2.8 *shudders*.... how do you find it now? powerhouse or slug? What I think is not much of a difference you may think is a lot.. You will lose power, as it changes the gearing on the car..

There are blokes on the patrol list runnin 33's and 35's on 2.8's and are happy with it. But the stock 2.8 GU I drove was a slug, so I wouldnt want to slow it more!

See if you can find a mate with 33s and try em for a run around the block.

Maybe cheaper!

Re: Clearance
I have 285/75/16 cooper S/T's on my Patrol with standard springs and there is a good clearance when unloaded. When loaded for a trip, there are times when the back wheels touch the wheel arches after going over a bump - but that is only because the standard springs are becoming soft.

$650!!!!

Maybe in Vic - here in NSW I believe it's still only around the $1-200 mark. (Good to see we're finally cheaper for something than Vic is!).

Well pays not to believe what others say.

Just called the Engineer, and its not the $650 we were told..

Try $275 + Vicroads costs.

to go from 31->35s on a GQ

1) Speedo Checked. + or 1 10%
(The ADR has wider gap than the cops 10% V 3%!. Even if it meets the ADR it may not pass the law ) Ringwood speedos is where to get it checked in Vic.

2) Additional rear refectors as your car goes up, it wont pass ADR 13
Reflectors are to be no more than 900 mm reflectors high. Stick on ADR approved reflectors on rear bumpers.

3) Headlights re-aimed.

4) to Engineer for a Brake and handling test.

5) Wheels dont hit anything at full droop or compression.

$ 300.00 inc Vic roads costs.

Remember tis is for tires only

You poor southeners!!!

Still legal to run 33's on a GU in Qld, without engineers certificate. Personally, I would even take my chances with 35's up here, even without a mod plate, cause it appears Mr Plod is to busy chasing those guy's in there rice burners to give a toss about a little bit more tyre under your fourby!!

If we all lived our live's to the letter of the law, we would never have any fun.

When was the last time you saw an accident which involved a fourby with bigger than standard boots?????????????????

Truckster,

Life is full of risks. It is a gamble modifying your fourby at all, but a gamble which some of us are prepared to take. Like I stated above, when was the last time you heard of a fourby, with larger than standard tyres, or any other mods for that matter, being involved in a serious accident?? I have never heard of one. You drive to suit the conditions, and therefore, you shouldn't have any problems.

And, what difference does an engineers certificate make, anyway. To run 35's, you don't have to modify anything that wouldn't have sorted anyway (ie: susp. lift, etc). So it all seems like a total waste of money to me.

And, if the worst did come to the worst, and someone did hit a child with their "illegaly modified fourby", they wouldn't spend the rest of their life in jail, because they would only, at worst, be convicted of manslaughter, and where remose is displayed, would probably only be sentenced for 2-3 years, with possible early parole.

You drive safe, and sensibly, for the road conditions, and the vehicle you are driving at all times. It doesn't matter what the hell you drive.
