17" AMG rims on a 2003 C320 mercedes

If your're rubbing on the fender and/or the strut tower, the tire is the wrong size- a lower profile tire will be needed to get the proper clearance.

if they rub, they are incorrect for this car. you probably have rims for an E class car, which will not fit a C class car.

you will have to use a lower profile tire.
