Wear On Both Edges: UNDER INFLATION

If a tire looks like this, it may be under inflated. The worst enemy a tire can have is too little inflation pressure. Under inflation reduces tread life through increased tread wear on the outside edges (or shoulders) of the tire. It also generates excessive heat that reduces tire durability. Finally, it reduces fuel economy through increased rolling resistance (soft tires cause your vehicle to work harder). Check your tires regularly for proper inflation. Abnormal tire wear may also be due to misalignment or mechanical problems. Many Goodyear retailers can provide expert diagnosis and repair.

Wear In Center: OVER INFLATION
When a tire is over inflated, the center of the tread bears most of the load and wears out faster than the outside edges. Uneven wear reduces the useful life of a tire. Check your tires regularly for proper inflation. Abnormal tire wear may also be due to misalignment or mechanical problems. Goodyear retailers can provide expert diagnosis and repair.

Cups or Dips in the tread: WORN PARTS
Cupping (also called dipping or scalloping) is most common on front tires, though rear tires can cup as well. It may be a sign that wheels are out of balance or that suspension or steering system parts are worn out. Many Goodyear retailers can provide expert diagnosis and repair.
