Provided is a pneumatic tire where a plurality of main grooves extending along the tire circumferential direction, lateral grooves extending in the direction inclined with respect to the tire width direction, and land portions partitioned by the main grooves and the lateral grooves are formed in a tread portion. The land portion includes an obtuse angle portion defined at an obtuse angle by the main groove and the lateral groove, and an acute angle portion defined at an acute angle by the main groove and the lateral groove. A plurality of holes are formed in a side wall of the land portion facing the main groove at intervals in the tire circumferential direction. The holes formed on an obtuse angle portion side are arranged at positions closer to a ground contact surface of the land portion than the holes formed on an acute angle portion side. |
