Vehicle Care
339
This condition not only shortens tire
life, but will adversely affect the
handling of your vehicle.
Rotating tires from one wheel
position to another is a way often
used to even out many types of
irregular wear or to avoid it
altogether. See
Irregular wear can be minimized by:
.
Using the right inflation pressure
for the load being carried.
.
Maintaining proper front wheel
alignment especially toe-in to
specifications.
.
Maintaining proper tire and
wheel balance.
.
Maintaining shock absorbers
and suspension components.
.
Maintain proper wheel bearing
adjustment.
Wheel Alignment and Tire
Balance
Maintaining front axle alignment is
very important to achieving
maximum tire life and vehicle
control. Inspecting steer axle tires in
the first 5 000 km (3,000 mi)
–
16 000 km (10,000 mi) of service
miles will generally show if tires are
wearing normally.
.
Rapid outside shoulder wear on
both tires indicates too much
toe-in.
.
Rapid inside shoulder wear on
both tires indicates too much
toe-out.
.
Excessive wear on the inside or
outside of one steer tire, but not
the other, can indicate a toe-in or
toe-out condition coupled with a
misaligned front or rear axle.
.
Pulling to the right or left can
indicate misalignment of the
front or rear axle, unequal tire
pressures, or a damaged /
mismatched tire.
Wheel Replacement

Warning
To prevent property damage,
personal injury, and/or death
always follow these
instructions when mounting
tires on wheels:
.
Only personnel who have
had proper training and
experience should mount
or remove tires from rims
or wheels.
.
Use only heavy-duty rims
or approved rims for
radial tires. It may be
necessary to contact
your wheel and rim
distributor to determine if
your rims are approved
for radial tires.
