TIRE CHAINS
Tire snow chains may be used on certain models.
Refer to Owner's Manual for more information.
CLEANING OF TIRES
Steam cleaning may be used for cleaning.
DO NOT use gasoline or wire brush for cleaning.
DO NOT use mineral oil or an oil-based solvent.
PRESSURE GAUGES
High-quality, dial-type, air-pressure gauges are
recommended. After checking with the gauge, re-
place valve cap and finger tight.
TIRE INFLATION PRESSURES
Under inflation (Fig. 2) causes rapid shoulder wear
and tire flexing.
Over inflation (Fig. 3) causes rapid center wear
and loss of the tire's ability to cushion shocks.
Improper inflation can cause;
²Uneven wear patterns
²Reduced tread life
²Reduced fuel economy
²Unsatisfactory ride
²Cause the vehicle to drift
Refer to the Owner's Manual for information re-
garding proper tire inflation pressure.
This pressure has been carefully selected to provide
for safe vehicle operation. Tire pressure should becheckedcoldonce per month. Tire pressure de-
creases when the outside temperature drops.
Inflation pressures specified on the placards are al-
wayscold inflation pressure. Cold inflation pres-
sure is obtained after the vehicle has not been
operated for at least 3 hours. Tire inflation pressures
may increase from 2 to 6 pounds per square inch
(psi) during operation.Do notreduce this normal
pressure build-up.
Vehicles loaded to the maximum capacity should
not be driven at continuous speeds above 75 mph
(120 km/h).
WARNING: OVER OR UNDER INFLATED TIRES CAN
AFFECT VEHICLE HANDLING AND CAN FAIL SUD-
DENLY, RESULTING IN LOSS OF VEHICLE CON-
TROL.
REPLACEMENT TIRES
OEM tires provide a proper balance of many fea-
tures such as;

²Noise
²Handling
²Durability
²Tread life
²Traction
²Rolling resistance
²Speed capability
Original equipment tires should be used when re-
placement is needed.
Refer to the placard on the vehicle or the
Owner's Manual for the correct replacement
tire.
Failure to use original or equivalent replacement
tires may adversely affect the handling of the vehi-
cle.
The use of oversize tiresis not recommended.
They may cause interference with vehicle suspension
and steering travel. This can cause tire damage or
failure.
WARNING: FAILURE TO EQUIP THE VEHICLE WITH
TIRES HAVING ADEQUATE LOAD CAPABILITY CAN
RESULT IN SUDDEN TIRE FAILURE.
ROTATION
Tires on the front and rear axles operate at differ-
ent loads and perform different steering, driving, and
braking functions. For these reasons, the tires wear
at unequal rates. They may also develop irregular
wear patterns. These effects can be reduced by rotat-
ing the tires according to the maintenance schedule
in the Owners Manual. This will improve tread life,
traction and maintain a smooth quiet ride.
The suggested method of tire rotation is thesame
side front to rearpattern (Fig. 4). Other rotation
methods can be used, but may not provide the same
tire longevity benefits.
TREAD WEAR INDICATORS
Tread wear indicators are molded into the bottom
of the tread grooves. When tread is 1.6 mm (1/16 in.),
the tread wear indicators will appear as a 13 mm
(1/2 in.) band across the tread width.
Tire replacement is necessary when indicators ap-
pear in two or more grooves Fig. 5).
REPAIRING LEAKS
For proper repairing, a radial tire it must be re-
moved from the wheel. Repairs should only be made
if the puncture is in thetread area(Fig. 6). If out-
side the tread area the tire should be replaced.
Deflate tire completely before dismounting tire
from the wheel. Use lubrication such as a mild soap
solution when dismounting or mounting tire. Use
tools free of burrs or sharp edges.
Before mounting tire on wheel, make sure all rust
scale is removed from the rim. Repaint or seal if nec-
essary.

WHEELS
GENERAL INFORMATION
Original equipment wheels are designed for the
specified Maximum Vehicle Capacity.
All models use steel or cast aluminum drop center
wheels. The safety rim wheel (Fig. 1) has raised sec-
tions between the rim flanges and the rim well.
Initial inflation of the tire forces the bead over
these raised sections. In case of tire failure, the
raised sections hold the tire in position on the wheel
until the vehicle can be brought to a safe stop.
Cast aluminum wheels require special balance
weights and alignment equipment.
WHEEL INSTALLATION
The wheel studs and nuts are designed for specific
applications. They must be 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 en-
larged nose. This enlarged nose is necessary to en-
sure proper retention of the aluminum wheels.
Before installing the wheel, be sure to remove any
build up of corrosion on the wheel mounting surfaces.
Ensure wheels are installed with good metal-to-metal
contact. Improper installation could cause loosening
of wheel nuts. This could affect the safety and han-
dling of your vehicle.
To install the wheel, first position it properly on
the mounting surface. All wheel nuts should then be
tightened just snug. Gradually tighten them in se-
quence to 129 Nzm (95 ft. lbs.) torque (Fig. 2).Never
use oil or grease on studs or nuts.
WHEEL REPLACEMENT
Wheels must be replaced if they have:
²Excessive runout²Bent or dented
²Leak air through welds
²Have damaged bolt holes
Wheel repairs employing hammering, heating, or
welding are not allowed.
Original equipment wheels are available through
your dealer. Replacement wheels from any other
source should be equivalent in:
²Load carrying capacity
²Diameter
²Width
²Offset
²Mounting configuration
Failure to use equivalent replacement wheels may
affect the safety and handling of your vehicle. Re-
placement withusedwheels is not recommended.
Their service history may have included severe treat-
ment.
Refer to the Specifications Chart for informa-
tion regarding above requirements.
WHEEL ORNAMENTATION
WARNING: HANDLE ALL WHEEL ORNAMENTATION
WITH EXTREME CARE DURING REMOVAL AND IN-
STALLATION. SHARP EDGES ON THE COVERS OR
CAPS CAN CAUSE PERSONAL INJURY.
TIRE AND WHEEL BALANCE
It is recommended that a two plane dynamic bal-
ancer be used when a wheel and tire assembly re-
quire balancing. Static should be used only when a
two plane balancer is not available.
For static imbalance, find location of heavy spot
causing imbalance. Counter balance wheel directly
opposite the heavy spot. Determine weight required
to counterbalance the area of imbalance. Place half
of this weight on theinnerrim flange and the other

WOODGRAIN OVERLAY
SERVICE INFORMATION
Exterior woodgrain overlay is a weather-resistant
vinyl. The adhesive backing is protected by a paper
liner until removed for installation.
OVERLAY REPAIR
Small nicks and scratches on an overlay can be
touched-up with paint.
To eliminate blisters and air bubbles, pierce them
with a needle or pin. Force the trapped air out of the
hole and press firmly on the overlay. Heat also can
be applied to remove small wrinkles.
Whenever an overlay must be stretched, do
not slit or cut it. Instead, apply heat and press
or squeegee the overlay into place.
INSTALLATION REQUIREMENTS
Overlay replacement requires metal repair and
paint refinish to be completed before the overlay is
installed.
The work area temperature should be between
18ÉC (65ÉF) and 32ÉC (90ÉF).A woodgrain overlay
should not be replaced if the work area temper-
ature is less than 18ÉC (65ÉF).
