Not all tire wear is caused by a defect in the tires themselves. There are several other components of the vehicle that, when faulty, can result in premature tire damage. In particular, bent or worn suspension parts can cause tire cupping; a condition that looks like scalloped dips around the edges of the tread. Any worn component that connects the wheel to the body of the car–including bushings, shock absorbers, ball joints, and wheel bearings—could be the source of this issue.
To fix the problem, all worn components must be replaced, and the tire should be balanced or moved to a different area of the vehicle. If you notice any cupping on your tires, bring your car in immediately before the tire becomes too worn. Lake Norman’s service and repair center is located in Mooresville, NC.
