2E – 2  TIRES AND WHEELS

DESCRIPTION AND OPERATION

TIRE

Tread

A part (that contacts) road surfaces directly is fixed on
the outside of carcass and breaker. It is a strong rubber
coat made of high anti–abrasion rubber. Its running per-
formance depends on is surface profile.

Breaker

A cord belt between tread and carcass prevents dam-
ages of inner code due to outer shock and vibration.

Carcass

This major part made by pilling code papers of strong
synthetic fiber forms a structure of tire. Since it main-
tains tire pressure and endures applied load and shock
to tire, it should have a high anti–fatigue characteristic.

Bead

A steel wire winding the ending part of carcass code,
coated with rubber film and wrapped with nylon cord pa-
pers. It fixes tire to a rim.

Tube

Tires used in mostly current vehicle are mostly tubeless
tires.

Side Wall

It is provided to improve the comfortable driving by pro-
tecting carcass and cushion movement.

TIRES AND WHEELS  2E – 3

Hydroplaning

The condition of driving a vehicle fast on the road surface
covered with water can cause tires to fail to rotate with a
good contact on the surface, so results in remaining them
afloat. This is so–called hydroplaning. It causes brake
failure, lower tractive force, and losing the steering per-
formance so it is very vulnerable condition.

D16A005A

Standing Wave

During running the rotating tire repeats deformation and
restoring movement generated in tread. But when the
wheel rotating speed reaches high, the next deformation
applied to tire before restoring last deformation so the
trembling wave appears in the tread portion. The lower
the tire pressure the severe the trembling wave appears.
And during the high speed.

D106A004

REPLACEMENT TIRES

A Tire Performance Criteria (TPC) specification number
is molded in the sidewall near the tire size of all original
equipment tires. This specification number assures that
the tire meets performance standards for traction, en-
durance, dimensions, noise, handling and rolling resist-
ance. Usually a specific TPC number is assigned to
each tire size.

Caution: Do not mix different types of tires on the
same vehicle such as radial, bias and bias-belted
tires except in emergencies, because vehicle han-
dling may be seriously affected and may result in
loss of control.

Caution: Do not change 145/70 R13 tires or 155/65
R13 tires for 175/60 R13 tires, because vehicle
hancling may be seriously affected and may result
in loss of control. If you change 145/70 R13 tires or
155/65 R13 tires for 175/60 R13 tires, you have to
change the steering gear assembly.

Use only replacement tires with the same size, load
range, and construction as the original. The use of any
other tire size or construction type may seriously affect
ride, handling, speedometer/odometer calibration, ve-
hicle ground clearance, and tire clearance to the body
and the chassis. This does not apply to the spare tire fur-
nished with the vehicle.

It is recommended that new tires be installed in pairs on
the same axle.

If it is necessary to replace only one tire, pair it with the
tire having the most tread to equalize the braking action.

Although they may appear different in tread design, tires
built by different manufacturers with identical TPC speci-
fications may be used on the same vehicle.

ALL SEASON TIRES

Most vehicles are now equipped with steel-belted all
season radial tires as standard equipment. These tires
qualify as snow tires, with a 37 percent higher average
rating for snow traction than the non-all season radial
tires previously used. Other performance areas, such as
wet traction, rolling resistance, tread life, and air reten-
tion, have also been improved. This was done by im-
provements in both tread design and tread compounds.
These tires are identified by an “M + S” molded in the tire
sidewall following the size number. The suffix “MS” is
also molded in the sidewall after the TPC specification
number.

The optional handling tires used on some vehicles are
not all season tires. These will not have the “MS” mark-
ing after the tire size or the TPC specification number.

TIRE LABEL

The tire label is permanently located on the rear face of
the driver’s door and should be referred to for tire infor-
mation. It lists the maximum vehicle load, the tire size
(including the spare tire), and the cold inflation pressure
(including the spare tire).

SPARE TIRE

This vehicle comes equipped with a full-sized spare tire
and wheel.

2E – 4  TIRES AND WHEELS

WHEELS

Wheels must be replaced if they are bent, dented, have
excessive lateral or radial runout, leak air through welds,
have elongated bolt holes, or if the wheel bolts won’t
stay tight or are heavily rusted. Wheels with excessive
runout may cause vehicle vibration. Replacement
wheels must be equivalent to the original equipment
wheels in load capacity, diameter, rim width, offset, and
mounting configuration. A wheel of improper size or type
may affect wheel and bearing life, brake cooling,
speedometer/odometer calibration, vehicle ground
clearance, and tire clearance to the body and the chas-
sis.

INFLATION OF TIRES

The pressure recommended for any vehicle line is care-
fully calculated to give a satisfactory ride, handling,
tread life, and load-carrying capacity.

Tire pressure should be checked monthly or before any
extended trip. Check the tires when they are cold, after
the vehicle has sat for 3 hours or more or has been driv-
en less than 1 mile. Set the tire pressure to the specifi-
cations on the tire label located on the rear face of the
driver’s door. Tire inflation pressure is also given under
“Tire Size and Pressure Specifications” in this section.

Valve caps or extensions should be on the valves to
keep dust and water out.

Higher than recommended tire pressure can cause:

D

Hard ride

D

Tire bruising or damage

D

Rapid tread wear at the center of the tire

Lower than recommended pressure can cause:

D

Tire squeal on turns

D

Hard steering

D

Rapid and uneven wear on the edges of the tread

D

Tire rim bruises and rupture

D

Tire cord breakage

D

High tire temperatures

Unequal tire pressures on same axle can cause:

D

Uneven braking

D

Steering lead

D

Reduced handling

D

Swerve on acceleration

D

Torque steer

ROTATION TIRES

Front and rear tires perform different jobs and can wear
differently depending on the tires of road driven, driving
habit, etc.

The front tires will wear faster than the rear ones.

To avoid uneven wear of tires and to prolong tire life, in-
spect and rotate the tires every 5,000 km (3,100 miles).
After rotating the tires, adjust the tire inflation pressures
and be sure to check wheel nuts tightness.

WHEEL BALANCE

Balance is the easiest procedure to perform and should
be done first if the vibration occurs at high speeds, or if
the tires or the wheels are replaced.

When proceeding the wheel balancing procedure regard
the belows.

1. Do not use the wheel weight over two at the inboard

and the outboard flanges.

2. The total weight of the wheel weights should not ex-

ceed the 100 grams (3.5 ounces).

3. Blanching the assemblies with factory aluminum

wheels requires the use of special nylon–coated,
clip–on wheel weights.
