Tire Wear Patterns
A tire that’s worn in the center and not on the shoulders is overinflated. An underinflated tire will wear on its outer edges. Incorrect alignment angles and worn suspension components result in premature tire wear.
The camber angle is the inward or outward tilt of the top of the tire as viewed from the front of the vehicle. Too much positive (+) camber will cause the outside tread of the tire to wear. Too much negative (-) camber will result in a worn inside tire tread. Worn struts, shocks, or incorrect toe results in tire cupping. Cupped tires will cause a growl that increases with vehicle speed.
