I recently put 20 inch rims on my RL . However when I go over bumps the back right tire scraps. It is only that tire I am having a problem with. I had the back struts replaced but cannot find the coil spting for the back. What should I do about the coil spring? Would spacers fix the problem? Is there another Acura with similar parts? I'm lost need help. It also happens when I turn left . No other tires are having this problem.

 

Which car are you talking about, a TL or an RL?

How about opting for a more realistic wheel and tire combination?

Assuming you're talking about an RL and assuming the offset of your wheels is correct, a 225/35 R20 should fit with no issues (but it will look silly).

 

perhaps get an alignment and add camber to that side.
