3E – 2 WHEELS AND TIRES

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.

All models are equipped with metric sized 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.

REMOVAL

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.

INSTALLATION

1. Wheel and Tire

2. Wheel Lug Nut

Tighten the wheel lug nuts to the specified torque in
numerical order.

Wheel Lug Nut Torque

N·m (kg·m/lb·ft)

118 (12.0 / 87)

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.

TIRES

REPLACEMENT

When replacement is necessary, the original metric size
should be used. Most metric tire sizes do not have exact
corresponding alphanumeric tire sizes. It is recommended
that new tires be installed in pairs on the same axle. If
necessary to replace only one tire, it should be paired with
tire having the most tread, to equalize braking traction.

CAUTION:
Do not mix different types of tires such as radial, bias and
bias-belted tires except in emergencies, because vehicle
handling may be seriously affected and may result in loss
of control.

TIRE MOUNTING

Remove valve cap on valve stem and deflate the tire.
Then use a tire changing machine to mount or dismount
tires.
Follow the equipment manufacturer’s instruction. Do not
use hand tools or tire lever alone to change tires as they
may damage the tire beads or wheel rim.

TIRE DISMOUNTING

Rim bead seats should be cleaned with a wire brush or
coarse steel wool to remove lubricants, and light rust.
Before mounting a tire, the bead area should be well
lubricated with an approved tire lubricant.
After mounting, inflate the tire to 196 kPa (28 psi) so that
beads are completely seated. Inflate the air to specified
pressure and install valve cap to the stem

WARNING:
NEVER STAND OVER TIRE WHEN INFLATING. BEAD MAY
BREAK WHEN BEAD SNAPS OVER RIM’S SAFETY HUMP
AND CAUSE SERIOUS PERSONAL INJURY.
NEVER EXCEED 240 kPa (35 psi) PRESSURE WHEN
INFLATING. IF 240 kPa (35 psi) PRESSURE WILL NOT
SEAT BEADS, DEFLATE, RE-LUBRICATE AND RE-INFLATE.
OVER INFLATION MAY CAUSE THE BEAD TO BREAK AND
CAUSE SERIOUS PERSONAL INJURY.

TIRE REPAIR

There are many different materials on the market used to
repair tires.
Manufacturers have published detailed instructions on
how and when to repair tires. These instructions can be
obtained from the tire manufacturer if they are not
included with the repair kit.
