Does anybody know if the rim sizes are different from front to back? I know the tire sizes are different. I was wondering if I could go with the same size tire on front to back. Or do I need to stick with the different tire size ?. The dealer told me that all 4 of my rims are bend and 700 bucks a piece to fix them. I find that hard to believe that all 4 are bend. So it's a lot cheaper to go with aftermarket wheels. At this point I'm looking for new rims and non run flat tires.
