Structure of Tire ▶
Tread
This thick layer of rubber provides the interface between the tire and the road. Wear-resistant
rubber is used to protect the carcass and belt against fractures and impacts and to deliver a long
driving life.
Shoulder
Located between the tread and sidewall, the shoulder rubber is the thickest so that the design
must allow for the easy diffusion of heat generated within the tire while driving.
Sidewall
The part between the shoulder and bead, the flexible sidewall protects the carcass and enhances
the ride. A tire’s ty
pe, size, structure, pattern, manufacturing company, product name and various
characters are indicated here.
Bead
The bead attaches the tire to the rim and wraps the end of the cord fabric. Comprised of the
bead wire, core, flipper and other parts, the bead is generally designed to be slightly tight around
the rim so that in the case of a sudden drop in inflation pressure, the tire will not fall off the rim.
Carcass
As the most important framework of a tire, the entire inner layer of cord fabric is called the
carcass. The carcass acts to support air pressure, vertical load and absorb shocks.

The contact area between the
ground and tire faces the
tread layer completely. Thus
the driving force and the
braking force are optimized,
and the tire is worn out evenly
resulting in increased life.The contact area between
the ground and tire is not
enough, so the tire is worn
out unevenly and the tire is
vulnerability to outside
influence.The contact area between the
ground and tire is excessive,
so a lot of heat is generated
and the tire is worn out
unevenly and abnormally.

During driving, the rotating tire repeats deformation and restoring movement in is tread. This
happens when the tire pressure is low in high speed driving.
However, when the wheel rotating speed is fast, the tire is deformed even before it is restored to
its original shape and the trembling wave appears on the tread portion. If this symptom lasts for
an extended period of time, the tire can be blown out in a short period of time.
If the standing wave symptom occurs on the tire, rubber on the tread comes off and eventually
the tire can be blown out which is very dangerous. When driving at high speed, the inflation
pressure should be increased to decrease heat generation due to extension and contraction
motion, to decrease hydroplaning and to prevent standing wave.
To prevent this symptom, it is recommended to increase the tire pressure 10 ~ 30 % higher than
the specified pressure value in high speed driving.

2. ABNORMAL TIRE SYMPTOM
Standing Wave ▶

13-16
When the vehicle is driven on a road surface covered with water at high speed, tires do not
contact with the road surface but rotate floating on a thin film of water.
It causes brake failure, lower traction force and losing the steering performance.
To prevent this, increase the tire inflation pressure, use tires with leaf shape tread which is not
worn. However, it is a best measure to drive slowly. Hydro Planing ▶

If weight is not equally distributed around the wheel, unbalance centrifugal force by the wheel
rotation produces vibration. As the centrifugal force is produced proportional to the square of the
rotating speed, the wheel weight should be balanced even at high speed. There are two types of
the tire and wheel balancing: static and dynamic. Abnormal vibration may also occur due to
unbalanced rigidity or size of tires.
Static Balance ▶
When the free rotation of the wheel is
allowed, the heavier part is stopped on the
bottom if the wheel weight is unbalanced and
this is called "Static Unbalance". Also, the
state at which tire's stop position is not same
is called "Static Balance" when the wheel is
rotated again. If the part A is heavier as
shown in the figure 1, add the balance weight
of a weight corresponding to unbalanced
weight from B to A to maintain the static
balance. If the static balance is not
maintained, tramping, up and down vibration
of the wheels, occurs.
Dynamic Balance ▶
The static unbalance of the wheel creates the
vibration in the vertical direction, but the
dynamic unbalance creates the vibration in
the lateral direction. As shown in the figure 2
(a), if two parts, (2) and (3), are heavier when
the wheels are under the static balance
condition, dynamic unbalance is created,
resulting in shimmy, left and right vibration of
the wheels, and the torque Fxa is applied in
the axial direction. To correct the dynamic
unbalance, add the balance weight of a same
weight for two points of the circumference of
the rim, A and B, as shown in the figure 2 (b),
and apply the torque in the opposite direction
to the torque Fxa to offset in order to ensure
smooth rotation of the wheel.
