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. If the length of the protrusions (500) is denoted as L, and the predetermined intervals are denoted as P, the relationship 0.75L <= P <= 10L is satisfied. Lateral grooves (60), which extend from the groove to a buttress (9) and have openings, are formed (60a) in the buttress (9). In a tread surface view of the tire (1), the lateral grooves extend on an angle with respect to the tread width direction (twd), and the angle of the lateral grooves with respect to the tread width direction (twd) is 15 degrees to 60 degrees. |
