Tire Diagnosis - Irregular or Premature Wear

Tire Wear

Tire Wear:

1 - Under-inflation, Hard Cornering, Lack of Regular Rotation
2 - Incorrect Wheel Alignment, Hard Cornering, Lack of Regular Rotation
3 - Incorrect Wheel Alignment, Shock Absorber Failure
4 - Over-inflation, Heavy Acceleration, Lack of Regular Rotation
5 - Normal Wear to the Wear Indicator

Inspection Procedure
1. Inspect the front tire wear.
2. Inspect the rear tire wear.
3. Rotate the tires if any of these conditions exist:
^ The amount of time or mileage since the last tire rotation matches the maintenance schedule.
^ The outer tread blocks are worn more than the middle tread blocks (1).
^ The outer tread blocks are worn more than the inner tread blocks (2).
^ The middle tread blocks are worn more than the outer tread blocks (4).
4. Measure the wheel alignment if any of these conditions exist:
^ The tread blocks have feathered edges (3).
^ The outer tread blocks are worn more than the inner tread blocks (2).
^ The inner tread blocks are worn more than the outer tread blocks (2).
5. Inspect the struts or the shock absorbers if the tire tread exhibits a cupped appearance (3).
