(Refer to 2 - SUSPENSION/WHEEL ALIGNMENT
- DIAGNOSIS AND TESTING)
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 (Fig. 23).
Excessive toe-in or toe-out causes wear on the
tread edges and a feathered effect across the tread
(Fig. 23).
DIAGNOSIS AND TESTING - TREAD WEAR
INDICATORS
Tread wear indicators are molded into the bottom
of the tread grooves. When tread depth is 1.6 mm
(1/16 in.), the tread wear indicators will appear as a
13 mm (1/2 in.) band (Fig. 24).
Tire replacement is necessary when indicators
appear in two or more grooves or if localized balding
occurs.
