I have a question. I am currently running 33 x 12.50 tires on a set of 15 x 10 wheels. Would switching to 33 x 10.50's be a good idea? And if so, would I need to switch to 15 x 8 wheels (I know this sounds a little dumb, but I dont have much expierence with off road vehicles) ? Any help would be great, as I think this would be a way to imorove gas mileage.

IMHO 12.50 tires on a 10 inch rim is worthless, but thats just me. A 10.50 tire on a 10 inch rim . . . I dont even know if the bead would hold. Honestly, switching from a 12.50 tire to a 10.50 tire isnt going to raise your gas mileage much. I would run 15x8's with a 12.50 tire and just run a little more air pressure in them. I run 35 psi in mine. :D Free flowing exhaust and a K&N air filter would probably be money better spent, I think. Good Luck. :8

I also would say to keep the 12.50's and get 8 inch rims.
