2E – 4 TIRES AND WHEELS

WHEELS

Wheels must be replaced if they are bent, dented, have
excessive lateral or radial runout, leak air through welds,
have elongated bolt holes, or if the wheel bolts won't
stay tight or are heavily rusted. Wheels with excessive
runout may cause vehicle vibration. Replacement
wheels must be equivalent to the original equipment
wheels in load capacity, diameter, rim width, offset, and
mounting configuration. A wheel of improper size or type
may affect wheel and bearing life, brake cooling,
speedometer/odometer calibration, vehicle ground
clearance, and tire clearance to the body and the chas-
sis.

INFLATION OF TIRES

The pressure recommended for any vehicle line is care-
fully calculated to give a satisfactory ride, handling,
tread life, and load-carrying capacity.
Tire pressure should be checked monthly or before any
extended trip. Check the tires when they are cold, after
the vehicle has sat for 3 hours or more or has been driv-
en less than 1 mile. Set the tire pressure to the specifi-
cations on the tire label located on the rear face of the
driver's door. Tire inflation pressure is also given under
"Tire Size and Pressure Specifications" in this section.
Valve caps or extensions should be on the valves to
keep dust and water out.
Higher than recommended tire pressure can cause:
D Hard ride
D Tire bruising or damage
D Rapid tread wear at the center of the tire
Lower than recommended pressure can cause:
D Tire squeal on turns
D Hard steering
D Rapid and uneven wear on the edges of the tread
D Tire rim bruises and rupture
D Tire cord breakage
D High tire temperatures
Unequal tire pressures on same axle can cause:
D Uneven braking
D Steering lead
D Reduced handling
D Swerve on acceleration
D Torque steer

ROTATION TIRES

Front and rear tires perform different jobs and can wear
differently depending on the tires of road driven, driving
habit, etc.
The front tires will wear faster than the rear ones.
To avoid uneven wear of tires and to prolong tire life, in-
spect and rotate the tires every 5,000 km (3,100 miles).
After rotating the tires, adjust the tire inflation pressures
and be sure to check wheel nuts tightness.

WHEEL BALANCE

Balance is the easiest procedure to perform and should
be done first if the vibration occurs at high speeds, or if
the tires or the wheels are replaced.
When proceeding the wheel balancing procedure regard
the belows.
1. Do not use the wheel weight over two at the inboard
and the outboard flanges.
2. The total weight of the wheel weights should not ex-
ceed the 100 grams (3.5 ounces).
3. Blanching the assemblies with factory aluminum
wheels requires the use of special nylon–coated,
clip–on wheel weights.
