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
• Strut dampers worn or damaged
