Tires Cupped

[jpalazzo]

I have a 1997 M3. I do not know why the inside of my tires keep cupping after I buy a new set of tires. I bought a K-Max chamber kit and put on the car. Still having problems. The road noise is driving me crazy. Can someone please tell me how to fix this problem. Thanks Jim.

Cupping can be caused by an unbalanced tire condition, faulty wheel bearings, loose parts, fatigued springs or weak shock absorbers. Check the condition of the shock by forcefully bouncing the front end of the car several times and releasing it on the down stroke. Failure of the vehicle to settle after two strokes suggests worn shocks or struts.

Is this cupping happeningn on the front or rear tires? If it's the fronts, worn control arm bushings and struts frequently cause this. I'd start by taking a look at the control arm bushings.
