Maintenance and Care
Owner Maintenance
NOTE
Always check tire pressure when tires are
l
cold.
Warm tires normally exceed recommended
l
pressures. Don't release air from warm tires
to adjust the pressure.
Underinflation can cause reduced fuel
l
economy, uneven and accelerated tire wear,
and poor sealing of the tire bead, which
will deform the wheel and cause separation
of tire from rim.
Overinflation can produce a harsh ride,
l
uneven and accelerated tire wear, and a
greater possibility of damage from road
hazards.
Keep your tire pressure at the correct
levels. If one frequently needs inflating,
have it inspected.
qTire Rotation
To equalize tread wear, rotate the tires if
irregular wear develops. According to the
scheduled maintenance charts.Refer to
Scheduled Maintenance on page 8-3.
During rotation, inspect them for correct
balance.
Forward
Do not include (TEMPORARY USE ONLY)
spare tire in rotation.
Also, inspect them for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:
Incorrect tire pressure
l
8-34
Improper wheel alignment
l
Out-of-balance wheel
l
Severe braking
l
After rotation, inflate all tire pressures to
specification (page 10-6) and inspect the
lug nuts for tightness.
CAUTION
Rotate unidirectional tires and radial
tires that have an asymmetrical tread
pattern or studs only from front to
rear, not from side to side. Tire
performance will be reduced if
rotated from side to side.
CAUTION
Limited-Slip Differential system;
don't use the following:
Ø Tires not of the designated size
Ø Tires of different sizes or types at
the same time
Ø Tires not sufficiently inflated
If these instructions aren't followed,
the rotation of the left and right
wheels will be different and will thus
apply a constant load on the limited-
slip differential.
This will cause a malfunction.
qReplacing a Tire
WARNING
Always use tires that are in good
condition:
Driving with worn tires is dangerous.
Reduced braking, steering, and
traction could result in an accident.
