FIELD: automotive industry; tire industry.
SUBSTANCE: according to invention, tread band of tire contains at least one first sector passing along radius and consisting of first elastomer material; great number of second sectors passing along radius, arranged at opposite sides relative to axis of at least one first sector and consisting of second elastomer material; at least one longitudinal groove formed in at least one first sector and passing mainly over entire periphery of tread band. First elastomer material has modulus of elasticity at compression at 23°C of second elastomer material. Modulus of elasticity at compression at 23°C of first elastomer material is approximately from 20 to approximately 80 MPa.
EFFECT: improved draining capacity and road-keeping stability of tire on wet surface.
