PROBLEM TO BE SOLVED: To effectively suppress increase in temperature of a tread part caused by the traveling of a vehicle.SOLUTION: In a tire 1, a plurality of projections 500 are provided on a groove bottom 50B2 of a groove part and the projections 500 extend toward the other side wall 50B3 facing one side wall 50B1 from one side wall 50B1 forming the groove part. The projections 500 are provided at every predetermined interval in the groove part. If the length of the projections is defined as L and the predetermined interval is defined as P, the tire satisfies the relation of 0.75L≤P≤10L. If the groove width of the groove part is defined as W and the length of the projections 500 in an orthogonal direction orthogonal to an extension direction of the groove part is defined as FW, the tire satisfies the relation of 0.4≤FW/W<1. |
