Tire Treads

When mention is made of the tread of a tire, what is being referred to is the rubber that is on the outside of the tire. This is the part of the tire that makes contact with the road, or surface upon which the vehicle is being driven. The purpose of the tread is to provide traction. However, as the tires continue to be used over time, the amount of traction that it provides will decrease. This is because the treads will wear down. When the tread wears down, it does not have to be the end of the life of that tire. Tires can be retreaded and then put back to good use.

In most treading, you will find what is called a tread pattern. The tread pattern is the pattern of grooves that are etched into the treading. Many people have the misconception that the patterns are the treading, rather than, simply, the grooves in the treading. This is a very common misunderstanding.

There are many types of pattern designs some of which offer different performance depending surface and weather conditions.

Tread Patterns

Key benefits of tread patterns

  • Thermal Radiation Effect
  • Improved Cornering And Stability
  • Water Dispersion
  • Enhanced Brake Force, Driving And Traction

Major Thread Patterns And Their Features

Unidirectional

High performance vehicle tire features the word “ROTATION” and a directional arrow, when the tire is fitted according to the prescribed direction, tire has ideal water dispensation capabilities.

Asymmetrical

Side facing outwards (inwards)
Multi patterns across the face of the tire, this feature offers increased performance and stability of cornering, outer portions usually feature large tread blocks, while smaller inner blocks displaces water.

Asymmetrical/ unidirectional

These dual pattern tires allows for high dry surface performance on both inner and outer treads, this kind of dual characteristics makes for performance flexibility.
