Tire rubbing
 

I just got me some STR Roms 17 on my 2012 Camry and I used the same tire I had on the stock ones, but every time I go over a dip or speed bump or put people in the back my wheel rubs on the wheel wall. Should I roll my fenders or get smaller tires. Its stock height

If the tires are the same size. Compare the new rim offset with the stock rim offset. It could be the new rims are sticking out father in the wheel well do to offset changes.

If so your best bet is get rims the fit the car or you will always be working around this issue. If you purchased the rims from a dealer have them change them out for something with an offset the same as a stock rim as they should have know what they were doing.

As to rolling the fenders first find out where the tire is hitting and if rolling will solve this problem.
