Tire Inflation Pressure
Inspect all tire pressures monthly
(including the spare) when the tires are
cold. Maintain recommended pressures
for the best ride, top handling, and
minimum tire wear.
Refer to the specification charts (page 10-
6).

Tire Rotation
To equalize tread wear, rotate the tires
every 12,000 km (7,500 miles) or sooner
if irregular wear develops. During
rotation, inspect them for correct balance.
Incorrect Tire Inflation:
Overinflation or underinflation of
tires is dangerous. Adverse handling
or unexpected tire failure could result
in a serious accident. Always inflate
the tires to the correct pressure (page
10-6).
WARNING
NOTE
• Warm tires normally exceed
recommended pressures. Don
’t
release air from warm tires to adjust
the pressure.
• Underinflation can cause reduced
fuel economy 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 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.

Also, inspect them for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:
•Incorrect tire pressure
• Improper wheel alignment
• Out-of-balance wheel
• Severe braking
After rotation, inflate all tire pressures to
specification (page 10-6) and inspect the
lug nuts for tightness.
Replacing a Tire
If a tire wears evenly, a wear indicator will
appear as a solid band across the tread.
Replace the tire when this happens.
You should replace it before the band is
across the entire tread.
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 weakened if rotated from side
to side.
Limited-Slip Differential system;
don
’t use the following:
• Tires not of the designated size
• Tires of different sizes or types at
the same time
• 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.
CAUTION
CAUTION
Worn Tires:
Driving with worn tires is dangerous.
Reduced braking, steering, and
traction could result in an accident.
Always use tires that are in good
condition.

Temporary Spare Tire
Inspect the temporary spare tire at least
monthly to make sure it
’s properly
inflated and stored.
The temporary spare tire is easier to
handle because of its construction. It is
lighter and smaller than a conventional
tire and should be used only for an
emergency and only for a short distance.
Use the temporary only until the
conventional tire is repaired, which should
be as soon as possible.
Maintain its pressure at 420 kPa (4.2 kgf/
cm
2or bar, 60 psi).

Replacing a Wheel
When replacing a wheel, make sure the
new one is the same as the original factory
wheel in diameter, rim width, and offset.
Proper tire balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tires can cause
vibration and uneven wear, such as
cupping and flat spots.
• Don
’t use your temporary spare tire
rim with a snow tire or a
conventional tire. Neither will
properly fit and could damage both
tire and rim.
• The temporary spare tire has a tread
life of up to 5,000 km (3,000 miles),
depending on road conditions and
driving habits.
• The temporary spare tire is for
limited use, however, if the tread
wear solid-band indicator appears,
replace the tire with the same type
of temporary spare (page 8-29).
CAUTION
Using a Wrong-Sized Wheel:
Using a wrong-sized wheel is
dangerous. Braking and handling
could be affected, leading to loss of
control and an accident. Always use
wheels of the correct size on your
vehicle.
A wrong-sized wheel may adversely
affect:
•Tire fit
• Wheel and bearing life
• Ground clearance
• Snow-chain clearance
• Speedometer calibration
• Headlight aim
• Bumper height
