Rubber compounds of internal layers on the basis of natural rubber increase tyre service life. Great number of "rain elements" in different blocks of tread accelerates water drainage, providing excellent tyre performance on wet surface.
Solid center rib of trapezoidal shape provides high roadholding ability of the car at any speed rate. Special design of wide longitudinal grooves improves gripping characteristics on dry road.
Arc-shaped grooves, that have different depth along the length, increase the rigidity of lateral rib thereby improving road-holding ability and handling. Shoulder ribs are designed as solid ones to increase rigidity that means to increase grip on dry road including road-holding ability when turning.
