1. OVERVIEW

A radial tire uses a cord angle of 90 degrees. That is, the cord material runs in a radial or direct line

from one bead to the other across the tread. In addition, a radial tire has a belt overwrap under the

tread surface to provide greater structural stability. The belt overwrap of a radial tire distortion while the

radial structure enables high speed driving.

Tire supports the weight of the vehicle, reduces the impact from the road and at the same time,

transmits the power to propel, brake and steer on the road. It also functions to maintain a
vehicle’s movement. In order to complete such tasks, a tire must be structured to be a resilient

vessel of air.

There is wear limit mark on the tire, which protrudes as a strip shape located approximately 1.6 mm

from the groove bottom. This wear limit mark is not seen from the outside so there is additional
"▲" mark on the shoulder to let the driver find the wear mark easily. To measure the tire groove

depth, measure at any point other than the point which has a wear limit mark.

The tire is worn unevenly according to the driver's driving habit, improper servicing, low tire inflation

pressure, changed tire location, etc.

1) 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 type, 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.

3) Tire Inflation Pressure (35 psi)

Proper inflation pressure

Excessive inflation pressure

Low inflation pressure

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.
