Types of Tread

Asymmetrical
Asymmetrical

Asymmetric and directional tread patterns have v-shaped tread grooves that are offset compared to the centerline of the tire. Tires featuring asymmetric and directional tread patterns must be treated as directional tires for tire rotation.

Directional
Directional

A directional tread pattern is designed to roll only in one direction. That’s why you’ll see arrows on the sidewalls pointing in the direction that tire needs to be mounted. They can only be rotated front to back.

Directional/Asymmetrical
Directional/Asymmetrical

Directional tread patterns (aka unidirectional tread patterns) A directional tread pattern is designed to roll only in one direction. That’s why you’ll see arrows on the sidewalls pointing in the direction that tire needs to be mounted.

Symmetrical
Symmetrical

Superior dry performance because tread dissipates heat while a solid centre rib keeps the tire rigid for high-speed stability. Symmetric tread patterns. A symmetric tread pattern is the most common. It uses continuous ribs or independent tread blocks across the entire tread face, that often create a wavy design. The pattern on each side of the centre is the same.
