The plurality of land portions are formed of blocks and a rib, and are defined in a tread part of the pneumatic tire. The fine grooves with a depth of 0.1 mm to 0.8 mm, a width of 0.1 mm to 0.8 mm and a pitch of 0.5 mm to 2.0 mm are formed in the tread surface of each of the land portions to be inclined at an angle of 42° to 60° relative to the circumferential direction of the tire. The inclined directions of the fine grooves relative to the circumferential direction of the tire are reverse to each other on the left and right sides of the equator of the tire.
