Dry Touch concept
The Dry Touch 2 sipes remove the water from between the tyre and the driving surface and guide it into the wide main grooves through the rib’s centre groove. The sipe’s contour ensures that the high-performance tyre has excellent wet grip, even when worn. The unique sipe is larger at the bottom, which ensures higher groove volume even for a worn tyre.
Coanda Technology is applied in order to accelerate the removal of water on the inner shoulder. The curved, ramp-like design of the tread blocks on the inner shoulder guides the flow of water from the longitudinal groove into the transverse groove. The Flow Guide on the tread block doubles the effect by further accelerating the removal of water from below the vehicle along the transversal groove.
