a plurality of protrusion portions formed on at least one tire side portion of tire side portions located on both sides in a tire width direction, the protrusion portions projecting from a tire side surface that is a surface of the tire side portion and extending along the tire side surface,

the protrusion portions having an angle α within a range of no less than 6% and no more than 50% of an angle of one round in a tire circumferential direction, the angle α being relative and in the tire circumferential direction between two protrusion portion end position lines that respectively extend in a tire radial direction through different end portions of both end portions in an extending direction of the protrusion portions,

the tire side portion having a thickness at a tire maximum width position within a range of no less than 3 mm and no more than 9 mm,

the protrusion portions comprising at least one bent portion at a position where a direction in which the protrusion portions extend changes,

the protrusion portions each having a first end further inward in the tire radial direction than a second end,

the at least one bent portion being closer to the first end than to the second end, and

in the protrusion portions, a position of a portion in the tire radial direction where a height from the tire side surface is highest being radially inward of the at least one bent portion and closer to the first end than to the second end, the position where the height the portion of the protrusion portions is highest being lie point along the protrusion portions and all other positions along the protrusion portions have a smaller height than the position where the height is highest.
