Circumferential recesses which are recessed inward in the tread width direction and extend in the tire circumferential direction are formed in the outer surfaces of tire side sections. The circumferential recesses have formed thereon: first blocks protruding outward in the tire tread width direction, the first blocks having radial outer end sections located further toward the outside in the tire radial direction than the centers of the circumferential recesses in the tire radial direction, the first blocks also having radial inner front end sections located further toward the inside in the tire radial direction than the radial outer end sections; and second blocks protruding outward in the tire tread width direction, the second blocks having radial inner end sections located further toward the inside in the tire radial direction than the centers of the circumferential recesses in the tire radial direction, the second blocks also having radial outer front end sections located further toward the outside in the tire radial direction than the radial inner end sections. The radial inner front end sections of the first blocks and the radial outer front end sections of the second blocks are separated from each other in the tire circumferential direction or in the tire radial direction. |
