GENERAL INFORMATION
OEM wheels are designed for operation at all loads
up to the 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 A.
Initial inflation of the tire forces the bead over
these raised sections. In case of tire failure the raised
sections help 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 and must be replaced with equivalent
parts. Do not use replacement parts of lessor 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 ensure
proper retention of the wheel.
Before installing the wheel, be sure to remove any
build up of corrosion on the wheel mounting surfaces.
Installing wheels without good metal-to-metal contact
could cause future loosening of wheel nuts. This could
adversely affect the safety and handling of your ve-
hicle.
To install the wheel, position it properly on the
mounting surface using the hub pilot as a guide. All
wheel nuts should be lightly tightened before progres-
sively tightening them in sequence (Fig. 2). Tighten
wheel nuts to 129 N
z
m (95 ft. lbs.). Never use oil or
grease on studs or nuts.
WHEEL REPLACEMENT
Wheels must be replaced if they:
•
have excessive run out
•
are bent or dented
•
leak air through welds
•
have damaged bolt holes
Wheel repairs employing hammering, heating, or
welding are not allowed.
Original equipment replacement wheels are avail-
able through your dealer. When obtaining wheels
from any other source, the replacement wheels should
be equivalent in load carrying capacity. The wheel
dimensions (diameter, width, offset, and mounting
configuration)
must match original equipment
wheels. Failure to use equivalent replacement wheels
may adversely affect the safety and handling of your
vehicle. Replacement with used wheels is not
recommended as their service history may have
included severe treatment or very high mileage.
TIRE AND WHEEL BALANCE
Balancing need is indicated by vibration of seats,
floor pan, or steering wheel when driving over 90
km/h (55 mph) on a smooth road.
It is recommended that a two plane dynamic bal-
ancing machine be used when a wheel and tire as-
