To increase the contrast between a tread surface and a groove in a tire and to suppress deterioration of drainage from the groove.SOLUTION: A tire 10 has a circumferential groove 22, and plural projections 32, 42. The circumferential groove 22 is formed on a tread surface 12 and is opened toward a tire radial direction outer side. The plural projections 32, 42 have a projection height of 0.1 (mm) or more and 1.0 (mm) or less from a groove bottom surface 22A or a groove side surface 22B of the circumferential groove 22, and are formed at an interval of 0.1 (mm) or more and 1.0 (mm) or less. Further, center lines MA, MB, which connect tip side middle points and base end middle points of the plural projections 32, 42, are inclined with respect to perpendicular lines HA, HB so that the tip sides are positioned on a downstream side in a tire rotation direction with respect to the base end sides when viewed from a tire width direction or a tire radial direction.SELECTED DRAWING: Figure 3B
