A groove bottom (50B2) of a groove in a tire (1) is provided with multiple protrusions (500). The protrusions (500) extend from one side wall (50B1) to the other side wall (50B3) facing the one side wall (50B1), said side walls forming the groove. The protrusions (500) are disposed at predetermined intervals in the groove. Lateral grooves (60), which extend from the groove to a buttress (9) and have openings, are formed (60a) in the buttress (9). Air supply mechanisms (100R) that supply air are provided to the lateral grooves (60). |
