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. A relationship of 0.75L‰¤P‰¤10L is satisfied where L denotes a length of the projection parts (500) and P denotes the predetermined intervals. In addition a relationship of 0.4‰¤FW/W<1 is satisfied, where W denotes a groove width of the groove portion and FW denotes a length of the projection parts (500) in an orthogonal direction which is orthogonal to the extending direction of the groove portion. |
