Cupped Tires
Irregular and Premature Wear
Irregular and/or premature wear has many causes.
Some of them are incorrect inflation pressures, lack of tire
rotation, poor driving habits or improper wheel alignment.
Incorrect inflation is common cause of tire premature
wear.
Possible cause
Worn wheel bearings.
Broken or sagging springs.
Leaking caliper.
Warped discs.
Badly worn brake pads.
Tires are inflated unequally.
Broken or sagging springs.
Vehicle overloaded.
Incorrect springs.

Loose stabilizer bar.
Faulty shock absorber, struts or

Broken or sagging springs.
Vehicle overloaded.
Worn wheel bearings.
Excessive tire or wheel run out.
Worn ball joints.
Tire out of balance.
NOTE: Due to their design, radial tires tend to wear faster
in the shoulder area, particularly on the front tires. This
makes regular rotation especially necessary. After
rotation, be sure to check wheel nut torque, and set tire
pressures.
