[QUOTE=JoeFromPA]Hey Topless,
That's an interesting comment. I haven't considered running wheels that are 1.5" difference in width with the same tire.
Do you know anyone who has done that, even with a 1" difference? I have no experience in that, but i'd imagine that's alot different tire support of the sidewall. I'd think it'd be easy to de-bead the 225 wide tire fitted on a 8.5" rim with hard cornering. (=QUOTE)
Michelin, Bridgestone, Nitto and Dunlop all say that a 225 tire will fit 7-8.5 rims. I defer to their tire knowledge and expertise.
