I don't notice any difference except for MPG. I think I lost about two or three. Any bigger and I think it would involve body cuts/welding and too much CV pressure.

If you go taller than 33" you should think about re-gearing. If you don't I think you'll find that the auto trans will 'hunt' for the right gear when going uphills (freeway)

I installed 33" tires about 5K miles after I bought my FJ. I lost about 1.5 to 2 mpg on my commute to and from work. The transmission does not have a problem "hunting" for a gear. The stock tires are 32" already so going to 33's is not much of an increase, less than 10%.

I agree with dapit, if you go bigger than 33's you may want to regear.

I have a set of used Goodyear MTR's. 285/70R17 ~ roughly 33's. has about 80-90% tread on them. looking to get $600 for the set of 5. Only reason I took them off is because I upgraded to 35's.

Thanks I'll keep these in mind. How would you rate the road noise? From 1 - 10, 10 being really noisy. I was thinking of a tire that is more a of an AT, BFG, Tera Grapler, TOYO, etc. MT's seem to be a too noisy for me.

Anybody want to rate the noise of their tires?

i have Bridgestone Dueler AT Revo tires and love them. just wish they looked a bit more aggressive. i took into account the percentages (on-road vs. off-road), road noise and wear and figured ATs were the most cost effective for me. ideally, if i had a garage, i would run ATs and have a spare set of MTs ready to go for tougher trails. in terms of rating road noise, i would say very low - perhaps a 3? let me know if you want to test drive my truck.

I followed Potato's lead on this and haven't regretted it.

I've had 12.50x33"/17's for about two years now with the only "problems" being gas mileage. For me i lost about 3 MPG. Other than that no problems.

I installed P265/70R-17 Michelin LTX A/T 2 back in January...LOVE THEM! Extreamly quiet "1" and awesome in the mud. Try www.tirerack.com for the best deal.
