When your tires become worn down in an uneven pattern, it can be a sign of minor or major car repair issues, from inflation to alignment and shock absorption. If you see any of these abnormal tread wear patterns in your car tires, visit a mechanic, or see the link below for more detail.
What to look for: Notice if your tires are more bald in the center of wheel compared to the outside rim. Use a penny or the rounded end of a paperclip to measure the depth of tread.
What to look for: Check if your tires are becoming more bald on the edges than in the center. The edges will be more rounded than new tires.
What to look for: Brush your palm over the surface of the tire going in opposite directions. If the surface feels smooth in one direction and spiky in the other, you have feathering.
What to look for: If you have spoon-like dips and depressions on the surface of the tire, particularly on the outside edge, you have cupping.
What to look for: Examine your tires from the front of car and the back of the car. If one edge of the tire is more rounded than the other, you have an alignment issue.
Visit a car diagnostic center to find the root cause of the uneven tread wear. Rotating your tires isn't enough.
