A tire comprising: a central land region delimited by a pair of circumferential direction main grooves (71, 72) extending in a tire circumferential direction; the central land region is provided with a block row delimited by one or a plurality of circumferential direction narrow grooves (61, 62) having a groove width narrower than the circumferential direction main groove (71, 72) and extending in the tire circumferential direction; the block row has a plurality of land blocks (100, 200) delimited by width direction grooves extending in a tire width direction, wherein the width direction groove includes: a width direction groove portion (310, 320); and at least one bent portion (330, 340) which is continuous to the width direction groove portion (310, 320) and is bent in the tire circumferential direction, wherein a groove width of the bent portion (330, 340) along the tire width direction becomes narrower as the bent portion (330, 340) advances along the tire circumferential direction, an adjacent block row adjacent to the block row in the tire width direction across the circumferential direction narrow groove has an adjacent land block in which a sipe extending in the tire width direction is formed; and the sipe is positioned between one end of the width direction groove portion in the tire circumferential direction and another end of the width direction groove portion in the tire circumferential direction. a central land region delimited by a pair of circumferential direction main grooves (71, 72) extending in a tire circumferential direction; the central land region is provided with a block row delimited by one or a plurality of circumferential direction narrow grooves (61, 62) having a groove width narrower than the circumferential direction main groove (71, 72) and extending in the tire circumferential direction; the block row has a plurality of land blocks (100, 200) delimited by width direction grooves extending in a tire width direction, wherein the width direction groove includes: a width direction groove portion (310, 320); and at least one bent portion (330, 340) which is continuous to the width direction groove portion (310, 320) and is bent in the tire circumferential direction, wherein a groove width of the bent portion (330, 340) along the tire width direction becomes narrower as the bent portion (330, 340) advances along the tire circumferential direction, an adjacent block row adjacent to the block row in the tire width direction across the circumferential direction narrow groove has an adjacent land block in which a sipe extending in the tire width direction is formed; and the sipe is positioned between one end of the width direction groove portion in the tire circumferential direction and another end of the width direction groove portion in the tire circumferential direction. a width direction groove portion (310, 320); and at least one bent portion (330, 340) which is continuous to the width direction groove portion (310, 320) and is bent in the tire circumferential direction, wherein a groove width of the bent portion (330, 340) along the tire width direction becomes narrower as the bent portion (330, 340) advances along the tire circumferential direction, an adjacent block row adjacent to the block row in the tire width direction across the circumferential direction narrow groove has an adjacent land block in which a sipe extending in the tire width direction is formed; and the sipe is positioned between one end of the width direction groove portion in the tire circumferential direction and another end of the width direction groove portion in the tire circumferential direction. a groove width of the bent portion (330, 340) along the tire width direction becomes narrower as the bent portion (330, 340) advances along the tire circumferential direction, an adjacent block row adjacent to the block row in the tire width direction across the circumferential direction narrow groove has an adjacent land block in which a sipe extending in the tire width direction is formed; and the sipe is positioned between one end of the width direction groove portion in the tire circumferential direction and another end of the width direction groove portion in the tire circumferential direction.
