Patent ID: 7814951

Claim:
A pneumatic tire comprising a plurality of inclined lateral grooves in a tread extending from a tread edge toward a tire equatorial surface and being inclined with respect to a tire circumferential direction, with a forward rotation direction being specified such that the inclined lateral grooves contact the ground from a tire equatorial surface side thereof, wherein a plurality of fine grooves that have narrower widths than the inclined lateral grooves are formed in respective land portions provided between adjacent inclined lateral grooves in the circumferential direction and, in a land portion, a region at a forward rotation direction side has a larger amount of edging function in the axial direction of the tire caused by the fine grooves than a region at an opposite side, wherein at the land portion, a portion of the plurality of fine grooves are convexly curved toward the opposite side to the forward rotation direction and are formed so as to be connected along the inclined lateral groove, the convexly curved fine grooves are provided so as to direct from the groove wall of the inclined lateral groove at the forward rotation direction side toward the opposite side to the forward rotation direction without being opened at the inclined lateral groove located at the opposite side to the forward rotation direction.
