Abstract: A tire tread includes a middle rib formed by two circumferential main grooves extending along a tire circumferential direction, a first shoulder rib disposed axially outward from the center rib and one of the circumferential main grooves, and a second shoulder rib disposed axially outward from the center rib and the other of the two circumferential main grooves. The middle rib has a plurality of sipes inclined oppositely with respect to a tire rotational direction such that the sipes extend farther away from a rotational axis of the tire tread as the sipes extend in the tire rotational direction. The middle rib thereby defines a row of circumferentially extending tread elements having chamfers at trailing edges of the tread elements.
