2E-2  TIRES AND WHEELS

GENERAL

Tire And Wheel Balancing

There are two types of the tire and wheel balancing:
static and dynamic.

Static balance is the equal distribution of weight around
the wheel. Assemblies that are statically unbalanced
cause a bouncing action called wheel tramp. This
condition may eventually cause uneven tire wear.

Dynamic balance is the equal distribution of weight on
each side of the centerline so that when the assembly
spins there is no tendency for it to move from side to
side. Assemblies that are dynamically unbalanced may
cause wheel shimmy.

General Balance Precautions

Remove all deposits of foreign material from the inside
of the wheel.

Caution: Remove stones from the tread in order to
avoid operator injury during spin balancing.

Inspect the tire for any damage. Balance the tire

Structure of Tubeless Tube

DESCRIPTION AND OPERATION

The tire structure is different slightly according to the
types of the tire but a various type of the tire has the
common structure as following;

1. Tread

A part (that contacts) road surfaces directly is fixed
on the outsude of carcass and breaker.

It is a strong rubber coat made of high anti-abrasion
rubber. Its running performance depends on is
surface profile.

2. Breaker

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

3. Carcass

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

4. Side Wall

It is provided to improve the comfortable driving
by protecting carcass and cushion movement.

5. Bead

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

TIRE’S ABNORMAL ACTION

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 during the high speed.

2E-4  TIRES AND WHEELS

Caster is the tilting of the uppermost point of the
steering axis either forward or backward from the
vertical when viewed from the side of the vehicle. A
backward tilt is positive and a forward tilt negative.
Caster influences directional control of the steering but
does not affect tire wear.

Weak springs or overloading a vehicle will affect
caster. One wheel with more positive caster will pull
toward the center of the car. This condition will cause
the car to move or lean toward the side with the least
amount of positive caster. Caster is measures in
degrees and is not adjustable.

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 a float. This is so-called hydroplaning.
It causes brake failure, lower tractive force and losing
the steering performance so it is very vulnerable
condition.

WHEEL ALIGNMENT

The first responsibility of engineering is to design safe
steering and suspension systems. Each component
must be strong enough to with stand and absorb
extreme punishment. Both the steering system and
the front and the rear suspension must function
geometrically with the body mass.

The steering and suspension systems require that the
front wheels self-return and that the tire rolling effort
and the road friction be held to a negligible force in
order to allow the customer to direct the vehicle with
the least effort and the most comfort.

A complete wheel alignment check should include
measurements of the rear toe and camber.

Toe-in

Toe-in is the turning in of the tires, while toe-out is the
turning out of the tires from the geometric centerline or
thrust line. The toe ensures parallel rolling of the
wheels.

The toe serves to offset the small deflections of the
wheel support system which occur when the vehicle is
rolling forward.

The specified toe angle is the setting which achieves-
degrees “0¡Æ” of toe when the vehicle is moving.

Incorrect toe-in or toe-out will cause tire wear and
reduced fuel economy. As the individual steering and
suspension components wear from vehicle mileage,
additional toe will be needed to compensate for the
wear. Always correct the toe dimension last.

Camber

Camber is the tilting of the top of the tire from the
vertical when viewed from the front of the vehicle. When
the tires tilt outward, the camber is positive. When the
tires tilt inward, the camber is negative. The camber
angle is measured in degrees from the vertical. Camber
influnces both directional control and tire wear.

If the vehicle has too much positive camber, the
outside shoulder of the tire will wear. If the vehicle has
too much negative camber, the inside shoulder of the
tire will wear. Camber is measured in degrees and is
not adjustable.
