W CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were removed.
If a fastener needs to be replaced, use the correct part number fastener for that application. If the correct
part
number fastener is not available, a fastener of equal size and strength (or stronger) may be used.
Fasteners
that are not reused, and those requiring thread locking compound, will be called out. The correct
torque value must be used when installing fasteners that require it. If the above conditions are not
followed, parts or system damage could result.

GENERAL DESCRIPTION
Replacement wheels or tires must be equivalent to
the originals in load capacity, specified dimension
and mounting configuration. Improper size or type
may affect bearing life, brake performance,
speedometer/odometer calibration, vehicle ground
clearance and tire clearance to the body and chassis.

METRIC TIRE SIZE FORMAT
All model are equipped with metric sized tubeless
steel belted radial
tires. Correct tire pressures and
driving habits have an important influence on tire life.
Heavy cornering, excessively rapid acceleration and
unnecessary sharp braking increase
premature and
uneven wear.

3E-2 WHEELS AND TIRES
DIAGNOSIS
• Hard cornering • Incorrect wheel alignment
• Heavy acceleration from a stop • Under infration • Tire unevenly worn • Lack of rotation • Over inflation
Fig. 3E-2
IRREGULAR AND PREMATURE WEAR
(Fig. 3E-2)
Irregular and/or premature wear has many causes.
Some of them are incorrect inflation pressures, lack of
tire rotation, poor driving habits or improper wheel
alignment. Incorrect inflation
is common cause of tire
premature wear.
NOTE:
Due to their design, radial tires tend to wear faster in
the
shoulder area, particularly on the front tires. This
makes
regular rotation especially necessary. After
rotation, be sure to check wheel nut torque, and set tire
pressures.
TIRE ROTATION
Tire rotation is recommended to equalize wear for
longer tire life (Fig. 3E-3).
Acceptable rotation patterns
Fig. 3E-3
Spare tire
If the following conditions are noted, rotate the tires:
• Front tire wear is different from rear.
• Uneven wear exists across the tread of any tire.
• Left and right front tire wear is unequal.
•
Left and right rear tire wear is unequal.
Check wheel alignment if the following conditions are
noted:
• Left and right front tire wear is unequal.
•
Wear is uneven across the tread of any front tire.
• Front tire treads have a scuffed appearance with
"feather" edges on one side of the tread ribs or
blocks.
TREAD WEAR INDICATORS (fig. 3E-4)
The original equipment tires have built-in tread wear
indicators to show when tires need replacement.
These indicators may appear as wide bands. When the
indicators appear in
two or more grooves at three
locations, tire replacement is recommended.

INFLATION OF TIRES
Tire pressure, in cold condition (after vehicle has setfor
three hours or more, and driven less than one mile),
should
be checked monthly or before any extended
trip. Tire pressure increases
approximately 15% when
the tires become hot during driving. Tire pressure
specification is shown on the
label located on the left
door lock pillar (Fig. 3E-5).
Fig.
3E-5
NOTE:
Check the tire pressure whenever irregular wear is
found. Tire
inflation greatly affects tire wear. If the
alignment check does not reveal any alignment
problems,
check the condition of the shock absorbers
and
wheel/tire balance.
WHEELS AND TIRES 3E-3
DIAGNOSIS LIST
If the following conditions are noted, rotation is
required.
1. Front tire wear is different from rear.
2. Uneven wear exists across the tread of any tire.
3. Left and right front tire wear is unequal.
4. Left and right rear tire wear is unequal.
If
the following conditions are noted, check the wheel
alignment.
1. Left and right front tire wear is unequal.
2. Uneven wear exists across the tread of any tire.
3. Front tire treads have scuffed appearance with
"feather" edges on one side of tread ribs or
blocks.
4. There is cupping, flat spotting etc.
Higher than recommended pressure can cause:
1. Hard ride.
2. Poor steering stability.
3. Rapid and uneven wear at center of the tread.
Lower than recommended pressure can cause:
1. Tire squeal on turns.
2. Hard steering.
3. Rapid and uneven wear on the edges of the tread.
4. Tire rim bruises and rupture.
5. Tire cord breakage.
6. High tire temperatures.
7. Reduced handling.
8. Reduced fuel economy.
Unequal pressure on same axle can cause:
1. Uneven braking
2. Steering lead.
3. Reduced handling.
4. Swerve on acceleration

1. Wheel lug nut
• Loosen wheel nut by approximately 180• (half a
rotation) and raise the
vehicle. Then remove
the nuts.
2. Wheel and tire
NOTE:
Never use heat to loosen a tight wheel lug nut. The
application
of heat to the hub can shorten the life of the
wheel and may cause damage to wheel bearings.

\fl CAUTION: .
'({ Before installing wheels, remove any build-up of
corrosion on the wheel mounting surface and
brake disc
mounting surface by scraping and wire
brushing. Installing wheels without good metal­
to-metal contact at mounting surfaces can cause
wheel nuts to loosen, which can later allow a
wheel to come off while the vehicle is moving.
NOTE:
Valve caps should be on the valve stems to keep
dust and water out.
