Abstract
A tire wherein a first bulge part and a second bulge part are formed in a circumferential direction groove. The first bulge part has a narrow-tip shape such that, in the tire tread plan view, the size in the tread width direction diminishes along a first direction in the tire circumferential direction. The second bulge part has a narrow-tip shape such that, in the tire tread plan view, the size in the tread width direction diminishes along a second direction opposite to the first direction in the tire circumferential direction. A plurality of first bulge parts and second bulge parts are provided at predetermined intervals in the tire circumferential direction. A groove part which extends in the tire circumferential direction is provided between the first bulge part and the second bulge part which opposes the first bulge part in the tread width direction.
