A pneumatic tire has a pair of bead portions, side wall portions extending to an outer side in a tire diametrical direction from the bead portions, and a tread portion connected to an outer end in a tire diametrical direction of each of the side wall portions. An outer wall surface of the side wall portion is provided with a circumferential projection annularly extending along a tire circumferential direction, and a plurality of diametrical projections extending to an inner side in a tire diametrical direction from the circumferential projection and arranged so as to be spaced in the tire circumferential direction. A gap portion formed between the diametrical projections is open to an inner side in the tire diametrical direction.
