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.

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 ▶
