Tire Diagnosis - Irregular or Premature Wear
Tire Wear

Irregular and premature tire wear has many causes, the most common being:
- Incorrect cold tire inflation pressure
- Incorrect wheel alignment
- Lack of tire rotation
- Worn suspension parts
These conditions can often be diagnosed by visually inspecting the tire tread
for the following telltale symptoms:
Incorrect Cold Tire Inflation Pressure
Tread wear at center of tire- over-inflation.
- Frequent, aggressive acceleration
- Cold tire inflation pressure too high

Tread wear on edges of tire -- under-inflation.
- Hard cornering
- Cold tire inflation pressure too low
- Lack of rotation
Incorrect Wheel Alignment

- Tread is worn on one side of the tire more than the other.
- Tread blocks have scuffed, feathered or cupped appearance.
Lack Of Tire Rotation
Front tires worn more than rear tires.
Wheel/Tire Imbalance
Worn Suspension Parts
- Wheel bearing looseness
- Front suspension loose/worn
- Steering parts loose/worn
- Front control arm ball stud or bushing loose or worn
