Tyre Tread Patterns

Do tread patterns have a function?

Yes. Tyre tread patterns are designed to influence how a tyre performs in different conditions.

The grooves, blocks and sipes help the tyre maintain contact with the road and channel water away from the contact area. Different tread designs can also influence handling, braking, noise and comfort.

There is no single tread pattern that is best for every driver. The design is matched to the intended use of the tyre.

What is a symmetrical tread?

A symmetrical tread has the same pattern across the inner and outer portions of the tyre.

These tyres can provide predictable, balanced performance and are often designed with an emphasis on comfort and low noise. However, performance varies between individual tyre models, so a symmetrical pattern should not automatically be considered quieter or less performance-focused.

What is an asymmetrical tread?

An asymmetrical tread has different tread designs on the inner and outer portions of the tyre.

The different areas of the tread can be designed to perform different functions, such as providing handling and cornering performance while helping disperse water in wet conditions.

Asymmetrical tyres must be fitted the correct way around. Look for markings such as “Outside” and “Inside” on the sidewall.
