what is the best way to fit a set of 17" x 7.5" rims w/ 215/45/r17 tires the reason i ask is because every time i go over a bump my rear well digs into the side of the tire please help me!

 

You gotta roll your fenders. There is a lip that extends from the fenders and quarterpanels into the wheel well; roll it up. Make sure you use a heat gun on the paint first or it will crack. Ther is a website that teaches you how to do it, but i forgat the name...

I fit 18X7.5's on my car, and they don't rub at all with rolled fenders...
