22 - 16 TIRES/WHEELS
TIRES (Continued)
The use of tires smaller than the minimum tire
size approved for the vehicle can result in tire over-
loading and failure.
Use tires that have the approved load rating for
the vehicle and never overload them. Failure to equip
the vehicle with tires having adequate speed capabil-
ity can result in sudden tire failure and loss of vehi-
cle control.
The use of oversize tires may cause interference
with vehicle components. Under extremes of suspen-
sion and steering travel, interference with vehicle
components may cause tire damage.

DESCRIPTION - SPARE TIRE (TEMPORARY)

The compact temporary spare tire is designed for
emergency use only. The original tire should be
repaired or replaced at the first opportunity, then
reinstalled. Do not exceed speeds of 80 km/h (50
mph) when using the temporary spare tire. Refer to
Owner's Manual for complete details.

DIAGNOSIS AND TESTING

DIAGNOSIS AND TESTING - TIRE NOISE

Unusual tire noise can be associated with tire and
wheel vibration or irregular tire wear. For vibration,
(Refer to 22 - TIRES/WHEELS - DIAGNOSIS AND
TESTING). For irregular tire wear, (Refer to 22 -
TIRES/WHEELS/TIRES - DIAGNOSIS AND TEST-
ING).
DIAGNOSIS AND TESTING - TIRE/VEHICLE
LEAD
(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.
