Tire Wear Patterns Guide

Wear Patterns Are Clues, Not Proof

Tire wear patterns can point you toward possible issues, but they are not a diagnosis by themselves. Similar-looking wear can come from different causes, including inflation pressure, alignment, load, suspension condition, rotation practices, driving conditions, tire design, and tire quality.

Use this guide as a starting point. Always follow the vehicle and tire manufacturer's inflation, load, rotation, and service guidance. If the wear is severe, unusual, or getting worse, have the tire inspected by a qualified tire professional before making repair or replacement decisions.

Visual Reference

The image below shows common tread-wear pattern terms. Use it to describe what you are seeing, then compare that observation with the notes below.

What if my tire is wearing faster in the center?

Center wear means the middle of the tread is wearing faster than the shoulders. It may be associated with inflation pressure, vehicle load, tire construction, driving conditions, or how the tire is being used.

Do not assume center wear is caused by one issue. Check the vehicle placard, use the tire pressure recommended by the vehicle manufacturer, and have the tire inspected if the wear is severe, uneven, or continuing to worsen.

What if both shoulders are wearing faster?

Shoulder or edge wear means the outer areas of the tread are wearing faster than the center. It can be associated with inflation pressure, heavy loads, frequent cornering, alignment, suspension condition, road surface, or operating use.

Follow the vehicle and tire manufacturer's guidance for inflation pressure, load limits, and rotation intervals. If both shoulders are wearing quickly or the tire is showing heat damage, cracking, or exposed cord, have it inspected before continuing to use it.

What if only the inner or outer edge is wearing?

Wear concentrated on one shoulder can be a clue that the tire is not running evenly on the road. Possible contributors include camber alignment, toe alignment, worn or loose suspension parts, vehicle loading, tire position, or previous tire damage.

One-edge wear should not be diagnosed from appearance alone. If the wear is significant, compare the tire with the other tires on the vehicle and have the alignment, suspension, and tire condition checked by a qualified professional.

What if the tread looks feathered or scrubbed?

Toe wear or feathered wear can make the tread feel sharper in one direction than the other when you run your hand lightly across it. It may be associated with toe alignment, steering geometry, suspension condition, tire rotation practices, or road use.

Because this type of wear can develop gradually, it is useful to measure tread depth across the tire and compare readings from side to side. Do not assume an alignment adjustment is the only possible fix without inspection.

What if the tire has patchy or flat-looking wear?

Patch wear means one area of the tread looks more worn than the surrounding tread. Possible contributors include braking events, wheel balance, suspension condition, tire damage, irregular rotation history, road impact, or a tire quality issue.

If the tire vibrates, has visible damage, or the patch wear is deep enough to affect the tread shape, have the tire inspected. A visual pattern alone is not enough to determine whether the tire, wheel, suspension, or operating condition caused the wear.

What if the tread looks cupped or scalloped?

Cupping or scalloping describes repeated dips or choppy-looking areas around the tread. It may be associated with shocks, struts, suspension condition, wheel balance, tire rotation practices, tire construction, or long-term irregular wear.

Do not keep driving on a tire that is noisy, vibrating, badly cupped, or showing damage without having it inspected. Cupping can be a sign that more than one condition is involved.
