There is a BIG difference from a 35x12.5 on a 17 or 18" rim as opposed to running a 22.5 STEEL rim... Its not the size of the tire thats hurting, its the weight! Rear gears are a very valuable part of a drivetrain. They can ease the stress your drivetrain sees if you want to run a larger wheel/tire combo. Add more gear if you have a heavier setup and you can actually improve performance!
Yes...
I just installed a set on 22.5" with 255's and they are very heavy compared to the stockers. You can fill how much heavier the suspension feels. These where American Force wheels all 6, no steel on the inside. I am not sure how much the weight difference is between the American Force and Alcoa wheels but I know its alot more than 17's.
