A tire of the present invention comprises a plurality of land sections formed by a main groove which extends in a tire circumferential direction, and the land sections comprise a first land section which comprises a first groove wall of the main groove, and a second land section which comprises a second groove wall of the main groove. A groove in groove is formed in the main groove in the tire circumferential direction, and the groove in groove comprises a first circumferential direction groove portion which extends in the tire circumferential direction at the first groove wall; a first sloping portion which extends at a slope with respect to the tire circumferential direction from the first groove wall toward the second groove wall; a second circumferential direction groove portion which extends in the tire circumferential direction at the second groove wall; and a second sloping portion which extends at a slope with respect to the tire circumferential direction from the second groove wall toward the first groove wall. The first circumferential direction groove portion, the first sloping portion, the second circumferential direction groove portion, and the second sloping portion are formed repeatedly. |
