Tyre Pattern

  • Hidden grooves

    appear as the tyre wears. This creates new water channels & gripping surfaces, giving better wet grip traction.

  • Optimised block size

    Wide tread blocks enhance the tyre's rigidity and improve the mileage while delivering a low rolling resistance.

  • Tread Wear Equalised Stepper (T.W.E.S.)

    Small step-shaped blocks provide even wearing and prevent stone trapping, resulting in a long tyre life.

  • 3D Sipes

    deliver excellent mileage and traction during the whole tyre life by reinforcing interlocking between blocks.


Tyre Structure

Belt structure

The use of high rigidity belt cord minimises the deformation of the belt to maintain a flat tread/road contact. Delivers better grip and regular tread wear.

Carcass structure

Enhanced casing endurance by using premium carcass cord with improved fatigue resistance.

New sub tread & side wall compound

Fuel efficiency is improved by applying a new sub tread compound that reduces the tyre rolling resistance.

Enhanced casing endurance by applying new side wall compound with improved fatigue resistance and anti-crack performance.

New high durability cord

Enhanced durability by applying new steel cords.
