FIELD: automotive industry.

SUBSTANCE: invention relates to the automotive industry. A plurality of shoulder blocks (50A) are formed adjacent to each other in the tire circumferential direction on the outermost tire lateral direction by a main groove (12) extending in the tire circumferential direction on the tread surface (1A) of the tread portion and a plurality of minor grooves (51) crossing the main groove (12). The plurality of sipes (52) extend in the tire lateral direction on the tread surface (1A) of each of the plurality of shoulder blocks (50A) and are adjacent to each other in the tire circumferential direction.
