Abstract
A groove bottom of a groove in a tire is provided with multiple protrusions. The protrusions extend from one side wall to the other side wall opposed to the one side wall, the side walls forming the groove. The protrusions are disposed at predetermined intervals in the groove. If the length of the protrusion is denoted as L, and the predetermined intervals are denoted as P, the relationship 0.75 L≦P≦10 L is satisfied. Lateral grooves, which extend from the groove portion to a buttress and have openings, are formed in the buttress. In a tread surface view of the tire, the lateral grooves extend on an angle with respect to a tread width direction (twd), and the angle of the lateral grooves with respect to the tread width direction is 15 degrees to 60 degrees.
