A tire (1) is provided with multiple projection parts (500) in a groove bottom (50B2) of a groove portion. The projection parts (500) extend from one side wall (50B1) to the other side wall (50B3) opposed to the one side wall (50B1), the side walls forming the groove portion. The projection parts (500) are arranged at predetermined intervals in the groove portion. Lateral groove portions (60) that extend from the groove portion to a buttress section (9), and have openings (60a) in the buttress section (9) are formed.
