A pneumatic tire has a plurality of circumferential main grooves extending in the tire circumferential direction, a plurality of lug grooves extending in the tire width direction, and a plurality of blocks partitioned by the circumferential main grooves and the lug grooves. Also, the block has a bent groove having a bent shape that is convex in one direction and that extends in the tire circumferential direction dividing the block into two in the tire width direction. Also, the blocks that are adjacent to each other in the tire circumferential direction are disposed such that the bend directions of the bent grooves are alternately reversed.
