A tire includes a tread surface portion with inclined grooves, 2ND longitudinal grooves, and shoulder longitudinal grooves; and an indicator portion that indicates a rotation direction of the tire in which a vehicle travels forward. The inclined groove gradually extends forward in the rotation direction toward a tire equator from the outside in the tire width direction. A front surface among inner surfaces defining the inclined groove includes a first side surface with an inner end portion to which the 2ND longitudinal groove is open, a second side surface positioned closer to an inside than the first side surface and of which an outer end portion is positioned closer to a rear side than the inner end portion of the first side surface, and a stepped surface that connects an inner edge of the first side surface to an outer edge of the second side surface and faces the outside.
