Thanks for your reply. I am sorry, but when it comes to tires, wheels and suspensions I have very little knowledge. What do you mean by offset? Also I want to clarify my situation. The suspension doesn't bottom out, the front tires, especially the drivers side, hit the fender lips when I go too fast through a sharply angled dip. The rest of the time the car handles real well, one of the smoothest riding vehicles that I have ever had.

P.S. The rims are Mercedes rims, if this helps.
