A3 wheels question
 

Have a 2008 A3, Sline, with the 5 spoke Sline wheels. OEM tires are 225/45/17. It seems difficult to drive the car without getting some "curbing" marks on the wheels. The tire/wheel combo just
has very little protection, leaving the rim exposed and easy to damage. Since I wanted to get RS rep wheels anyway, is there a better tire size that may offer some rim protection while still looking
cool? Does anyone else find the 5 spokes easy to bang up? Any insight would be helpful. thanks! (ps audi newb, bear with me....)
