Odds are that you could probably fit these since they're narrower than the typical 35. Definitely stick with your factory rims or some aftermarket rims with the same offset. You may still need to do the pinch-weld mod and/or remove your mud flaps (if any).
Just got the Toyo Open Country A/T - LT285/75R18's on. They look GREAT. I have an 06 4x4 with the PRG leveling kit and they still rub though. I had to take the mud flaps off (I think it looks better without them anyway) but I still have some rubbing. Guess I'm going to have to do the pinch weld mod. These tires look giant compared to the stock tires. Very happy so far, but I was hoping to avoid the pinch weld mod.
I really don't notice it while I'm driving but I can see it when I look under the wheel well while setting still. I would think you would have the same results I did. Call Greg at PRG, he could tell you for sure.
Finally got the new tires. I went with Nitto Terra Grapplers in 275/70/r18. Got them installed for $212 a tire. Is that a fair price? They fit nicely on my 05 SE 2WD KC w/ the PRG 2.5" mini lift. Anything larger like the Toyo 285/75/r18 would most likely rub.
