In regions, divided by the tire equator, on both sides of the tread surface of a tire, the tire includes a grip area along the entire circumference of the tread, the grip area including a plurality of recessed lines, with a shape recessed toward an inner side of the tire from the outline of the tread surface, that extend from the tread edge side in a direction inclined relative to the tire equator and are arrayed in parallel, and a plurality of sipes that extend toward the tire equator in a direction inclined relative to the tire equator, starting in the grip area and terminating before the tire equator. The negative ratio in the grip area is higher than the negative ratio closer to the tire equator than the grip area.
