An Overview of Tyre Treads

The part of a tyre that comes in contact with the road surface is known as the tread. There are plenty of tyre tread patterns available in the market. A tread pattern on the tyre is responsible for providing grip and friction while driving. This helps in avoiding slipping-off of the car in wet conditions and handling for all types of driving scenarios. The pattern of treads can be easily tracked by noticing the tyre marks on the road.

Parts of a Tread

There are four parts of a tyre tread, namely, ribs, grooves, tread blocks and sipes.

  • Ribs are made up of tread blocks and constitute the raised section of the tread pattern.
  • Grooves are basically deep sections that run laterally or circumferentially around the tyre. They allow the water to expel from beneath the tyre and prevent hydroplaning.
  • Tread blocks are raised rubber segments that stick out from the tyre surface. These are responsible for ensuring smooth traction over dry surfaces.
  • Sipes are small, tiny, thin slots/slit. They create additional tread surface area for increased grip in wet, dry, and snowy conditions.

All the above-mentioned parts are together responsible for ensuring a smooth drive in all sorts of conditions. They can be arranged in a unique pattern to modulate the tyre’s performance in critical conditions.

Different Tread Patterns

Symmetrical Pattern

This is the most common type of tread pattern highly suitable for passenger car tyres Shirley but not for high-performance use. This pattern consists of ribs or tread blocks across the entire face of the tread. The same pattern is carried by both the halves of the tyre.

The symmetrical pattern ensures smooth driving, low rolling resistance and high directional-stability. These enhance flexible tyre rotation. Another attractive feature of this pattern is that it is not noisy and also increases fuel efficiency.

Asymmetric Pattern

A tyre featuring this tread pattern has two different tread designs. One design is present at the inner half of the tyre surface and the other on the outer half. Both halves have their purposes. The inner tread pattern helps in avoiding hydroplaning and the outer one has rigid tread blocks that provide lateral stiffness. This pattern provides high curve-stability and a good grip in wet conditions.

Directional Pattern

Tyres containing this pattern rotate in one direction only and usually have a chevron or arrow pattern on the tread surface. It is necessary that directional Goodyear tyres Shirley rotate in the right direction otherwise it is likely that you may not get the best of this design.

The arrow-shaped groves serve the purpose of resisting aquaplaning at high speeds by displacing water more efficiently through the tyre tread pattern. The extra traction ensured by this pattern provides better stability in mud or snow.

To get optimum tyre performance, always make sure that you buy all four Hankook tyres Shirley of the same pattern and not make a set of tyres with different tread patterns.
