Radial-ply tires have the same load-carrying capacity as other types of tires of the same size. They also use the
same recommended inflation pressures.
The use of oversized tires, either in the front or rear of the vehicle, can cause vehicle drive train failure. This could
also cause inaccurate wheel speed signals when the vehicle is equipped with Anti-Lock Brakes.
The use of tires from different manufactures on the same vehicle is NOT recommended. The proper tire pressure
should be maintained on all four tires.
TIRE PRESSURE FOR HIGH SPEEDS
For proper tire pressure specification refer to the Owners Manual.
REPLACEMENT TIRES
The original equipment tires provide a proper balance of many characteristics such as:
Ride
Noise
Handling
Durability
Tread life
Traction
Rolling resistance
Speed capability
It is recommended that tires equivalent to the original equipment tires beused when replacement is needed.
Failure to use equivalent replacement tires may adversely affect the safety and handling of the vehicle.
The use of oversize tires may cause interference with vehicle components.Under extremes of suspension and
steering travel, interference with vehicle components may cause tire damage.
WARNING: Failure to equip the vehicle with tires having adequate speed capability can result in sudden tire
failure.
TIRE INFLATION PRESSURES
WARNING: Over or under inflated tires can affect
vehicle handling and tread wear. This may cause
the tire to fail suddenly, resulting in loss of vehicle
control.
Under inflation will cause rapid shoulder wear (1), tire
flexing, and possible tire failure.

Over inflation will cause rapid center wear (1) reduc-
tion in the tire’s ability to cushion shocks.
Improper inflation can cause:
Uneven wear patterns
Reduced tread life
Reduced fuel economy
Unsatisfactory ride
Vehicle drift
For proper tire pressure specification refer to the vehicles Owners Manual.
DIAGNOSIS AND TESTING
PRESSURE GAUGES
A quality air pressure gauge is recommended to check tire pressure. After checking the air pressure, replace valve
cap finger tight.
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.
TREAD WEAR INDICATORS
Tread wear indicators (3) are molded into the bottom
of the tread grooves. When tread depth is 1.6 mm
(1/16 in.), the tread wear indicators (3) will appear as
a 13 mm (1/2 in.) band.
Tire replacement is necessary when indicators appear
in two or more grooves or if localized balding occurs.

WHEEL DESIGN
The rim size is on the vehicle safety certification label
located on the drivers door shut face. The size of the
rim is determined by the drivetrain package. Original
equipment wheels/rims are designed for operation up
to the specified maximum vehicle capacity.
All models use stamped steel, cast aluminum or
forged aluminum wheels. Every wheel has raised sec-
tions between the rim flanges (1) and rim drop well (3)
called safety humps.
Initial inflation of the tire forces the bead over these
raised sections. In case of rapid loss of air pressure,
the raised sections help hold the tire on the wheel.
The wheel studs and nuts are designed for specific
applications. All aluminum and some steel wheels
have wheel stud nuts with an enlarged nose. This
enlarged nose is necessary to ensure proper retention
of the wheels. Do not use replacement studs or nuts with a different design orlesserquality.
DIAGNOSIS AND TESTING
WHEEL INSPECTION
Inspect wheels for:
Excessive run out
Dents or cracks
Damaged wheel lug nut holes
Air Leaks from any area or surface of the rim
NOTE: Do not attempt to repair a wheel by hammering, heating or welding.
If a wheel is damaged an original equipment replacement wheel should be used. When obtaining replacement
wheels, they should be equivalent in load carrying capacity. The diameter, width, offset, pilot hole and bolt circle of
the wheel should be the same as the original wheel.
WARNING: Failure to use equivalent replacement wheels may adversely affect the safety and handling of
the vehicle. Used wheels are not recommended. The service history of the wheel may have included severe
treatment or very high mileage. The rim could fail without warning.
STANDARD PROCEDURE
WHEEL REPLACEMENT
The wheel studs and nuts are designed for specific applications. They mustbe replaced with equivalent parts. Do
not use replacement parts of lesser quality or a substitute design. All aluminum and some steel wheels have wheel
stud nuts which feature an enlarged nose. This enlarged nose is necessary to ensure proper retention of the alu-
minum wheels.
