TIRE

A tire includes a circumferential direction groove and plural protrusions. The circumferential direction groove is formed in a tread face so as to open toward an outer side in a tire radial direction. The plural protrusions are formed so as to project to a projection height of from 0.1 mm to 1.0 mm from a groove bottom face or a groove side face of the circumferential direction groove, and are spaced apart by a spacing of from 0.1 mm to 1.0 mm. A center line MA, MB linking a center point of a leading end side with a center point of a base end side of each of the plural protrusions leans with respect to a perpendicular line HA, HB such that the leading end side of the protrusion is positioned further toward a tire rotation direction downstream side than the base end side of the protrusion when viewed along a tire width direction or the tire radial direction
