285 70 17s

Hi Bob, With the FJ rims with +15 offset you will be ok running 285s, but you will probably have rubbing on the factory UCA. Steve and myself think about a +12 - +6 offset ideal and the tyre be just even with the guard.(won't stick out too far). A lift of at least 2" is needed as well to allow room for the tyre on flex but there might still be rubbing issues when flexing. Early next year i will have the rims and 285s on and will post up how they are going and any issues.

Cheers Derek

good to know, we have a trip to the flinders planed for Easter so I have between now and then to build up my Prado kind of behind tho didn't expect it to take 6 months to get my rims!

as for the UCA that's all I can see being a problem right now, maybe ill start a thread on UCA options.

I'm not sure if I'm missing something here, but... If a 265/70/17 tyre on the standard +25 offset 7.5" rim clears the UCA, then shouldn't a 285/70/17 tyre on a +15 offset 7.5" rim also clear the UCA?

What about gearing, have you thought about that?

Going to 285/70's you are going to be geared a lot higher than standard. Not ideal for towing and even touring top gear might be hard to hold. When 4wdriving LL will effectivly be a higher gear than standard, assuming your VX is an auto; down hill descents are going to be faster and less contolled with the bigger tyres.

I found enough of a difference with the 265/70's in gearing to make me think that if I went to 285's I would look seriously at changing diff ratios.

Superchargers overcome some of those problems

going up and down hills now I find my self manually changing gears more so down then up as I find I have more control over the car rather then using my brakes.

One thing I have found even with stock wheels was the traction control kicking in while cornering into a banked corner at speed. The first time scared the shit out of me to have the car lock up the wheels unexpectedly got the heart rate up. Now that I know about it I can anticipate it and I know the corners it does it on I brace my self for the "oh shit" moment, slowing down is an option I guess.

Has anyone done the before and after readings, maybe with a GPS, to work out speedo variations with the different sized tyres everyone is talking about. I'd be interested to find out, my brother put bigger tyres on a Bravo years ago but the speedo was out so far from factory that it actually corrected the 10 klm difference that the speedo had.

auto's might not be so bad with a 285. manual definately needs to be re-geared. i know from experience. not sure if it will be the same for the 150's, but i have a 120 which isn't too different.

a 265 tyre put my speedo spot on, as the factory was about 5% slower, and now on 285's, i'm about 8% faster than the speedo. this will change as the tyre wears down.

low range is too high now, and forget about towing anything heavy. a loaded box trailer of furniture or a tip run is fine, but forget about towing one of these...



i'm hanging out for a re-gear, but i have other plans that include a re-gear in about 18 months time.

I'm looking at fitting a 17x8 with +10 offset steel rim with MT's as a second set on a kakadu. I've fitted some 17x8 with 0 and they clear the front brakes.


can anyone tell me if the +10 will fit.??

Yes, I find bikes are quite slow in the twisty stuff and slow me down. At least the odd few have the courtesy to wave me past.

Hey guys, I have a 2012 150 Prado running a 2" lift and currently have no issues running 265/70/17's on stock rims with no rubbing. I have looked at running 285/70/17's, they fit and look awesome, but rub on the upper control arm on full lock. In SA you can go to a bigger tyre that is up to 50mm larger in circumference as I have inquired with Regency and insurance was ok. The only way is with new rims with the rear offset less I believe and only by approximately 10 - 15mm. Sppedo will also be very close to accurate as well..

You can also fit aftermarket Upper Control Arms which will also give extra clearance, whilst also correcting the geometry which goes out of whack with a lift..
