DIAGNOSIS AND TESTING - TIRE WEAR PATTERNS
Under-inflation will cause wear on the shoulders of tire. Over-inflation will cause wear at the center of tire.
Excessive camber causes the tire to run at an angle
to the road. One side of tread is then worn more than
the other.
Excessive toe-in or toe-out causes wear on the tread
edges and a feathered effect across the tread.
DIAGNOSIS AND TESTING - TIRE NOISE OR VIBRATION
Radial-ply tires are sensitive to force impulses caused by improper mounting, vibration, wheel defects, or possibly
tire imbalance.
To find out if tires are causing the noise or vibration, drive the vehicle over a smooth road at varying speeds. Note
the noise level during acceleration and deceleration. The engine, differential and exhaust noises will change as
speed varies, while the tire noise will usually remain constant.
