Tires have various tread patterns which match each of the purpose and requirement
1. Water draining effect.
2. Enhancement of the braking force, driving force and traction force.
3. Improvements in the cornering ability and stability.
4. Heat radiation effect.
Major tread pattern types and their features
Unidirectional tread pattern
A high-performance passenger car tire provided with a directional tread pattern carries the word “ROTATION”and an arrow symbol to indicate the direction of rotation. Fitting the tire according to the direction of rotation will improve the water draining effect significantly and allow optimum performance.
Asymmetrical tread pattern
SIDE FACING OUTWARDS(INWARDS)
Tread patterns change across the face of the tire. For increased stability during cornering. larger tread blocks are usually incorporated on the outer portion. The smaller inner blocks help to shed water.
Both asymmetrical and unidirectional pattern
A tire provided with both asymmetrical and directional tread patterns makes it possible to achieve high dry performance on the inner side of the tread. This kind of tire carries the characters and symbols that indicate both of these characteristics.
