DESCRIPTION AND OPERATION
WHEEL INFORMATION
Original equipment wheels are designed for proper
operation at all loads up to the specified maximum
vehicle capacity.
All models use steel or aluminum drop center
wheels. Every wheel has raised sections between the
rim flanges and rim drop well called safety humps
(Fig. 1).
Fig. 1 Safety Rim
Initial inflation of the tires forces the bead over
these raised sections. In case of air loss 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 to fit on the thicker flange of the rim and
special wheel clamps for the alignment equipment.
The wheel studs and nuts are designed for the spe-
cific wheel applications used on a vehicle and must
be replaced with equivalent parts.
Do not use replacement parts of lesser quality or of
a substitute design from the original equipment part.

All aluminum wheels have wheel stud nuts with
an enlarged nose. This enlarged nose is necessary to
ensure proper retention of the wheels.
Vehicles that are equipped with bolt-on wheel cov-
ers use large nose wheel nuts. The wheel nuts used
on a vehicle equipped with bolt-on wheel covers are
externally threaded so that the wheel covers can be
attached to the wheel nuts.
Before installing a wheel, remove any buildup of
corrosion on the wheel mounting surface.
WARNING: INSTALLING WHEELS WITHOUT GOOD
METAL-TO-METAL CONTACT COULD CAUSE LOOS-
ENING OF WHEEL LUG NUTS. THIS COULD
ADVERSELY AFFECT THE SAFETY AND HANDLING
OF YOUR VEHICLE.
DIAGNOSIS AND TESTING
WHEEL INSPECTION
Wheels must be replaced if they:
• Have excessive run out
• Are bent or dented
• Leak air
• Have damaged wheel lug holes
Wheel repairs employing hammering, heating,
welding or repairing leaks are not allowed.
Original equipment replacement wheels are avail-
able through the dealer. When obtaining replacement
wheels from any other source, they must be equiva-
lent in load carrying capacity. The wheel features
(diameter, width, offset, brake clearance, and mount-
ing configuration) must match the original equip-
ment wheels.
WARNING:
MENT REPLACEMENT WHEELS MAY ADVERSELY
AFFECT THE SAFETY AND HANDLING OF YOUR
VEHICLE.
