I think your real problem with 285/70R17's will be the diameter - that equates to 32.7" (831mm). Without spring spacers, this will rub fairly hard at access or whenever a wheel is compressed, and may foul at the front on lock.

Thanks Gordon,
That was the info I was chasing. I'm pretty set on getting as close to 33inch tyres as I can, and the BFG KM2's in a 285/70/17 look almost spot on.

And any time the KM2's are on I will be leaving the GOE Rods on the heightened setting,
Do you know if I would still get rubbing without going below off road height? If so then there goes the idea of the 285/70/17's.

I could always go for the 245/70/17's, considering they are 300 a tyre at Tempe at the moment, but to go to the 285/70/17 would be much more cool and awesome.

Cheers,
Ben

Legend, thanks Boofla.

You haven't tried a 33inch on those rims have you?

No and I wouldn't to be honest. Not on a sport anyway.

I've got 285/75-16s on my patrol and the other thing you need to know is the bigger the tyre the slower off the line you are going to be, more wear on the gearbox as well with extra strain.

Thanks

Forgot to mention, I'm not sure if you saw my thread on bob Jane but get a price from them and they will match any price and take off 10% of the difference between there price and your quote.

Cheers

Yeah another good point, don't want to put any more strain than necessary on the balsa wood auto box.

Hi Ben,

Neither LLAMS nor rods will stop 285/70R17 tyres rubbing when the wheel compresses up into the wheel-arch. On a D3, the only real solution for fitting 33" tyres are spacers between the air-spring and turret + rods, but that will need all the geometry re-aligned and reduces the reliability of the car. One of the US owners did it, but they're pretty lax on vehicle mods over there .....

The largest MT tyre you'll fit (in 17" rim size) is a 265/70R17. The individual tyre makes vary in actual diameter (versus calculated diameter). The largest I ever found was the Interco Super Swamper SSR, but I had to import them from the States (although Procomp did sell them for a while). It was just under 32.5" in diameter. It will still rub, but some creative cutting of the inner wheel liners will help.

Cheers,

Gordon

Since when is the gearbox weak - exceptionally reliable with few breakdowns - issue is lack of fluid changes causing issues not mechanical issues.

Same or similar box as the FG turbo falcons?
