I'm running 235/75/15 on 8" rally's today, but want to put some 255/60/17 on the truck. The 17" will have more backspacing, probably 5". Just looking at my current 27.5" setup, I've only got 3-4" between the tire and the inner fender. I just thought our suspension moved that much when going over bumps in the road.

I don't want to goof up my powder coated chassis!! Thanks for the input.
