Abstract:
To provide a pneumatic tire which can improve cooling performance of a tread part.SOLUTION: A pneumatic tire includes fins 4A, 4B which are arranged on side wall surfaces of blocks 3A, 3B and extend in a tire circumferential direction. A local plane X is defined by including ground ends of the first and second blocks 3A, 3B, and an arc connecting opening end parts of three lug grooves 2 for partitioning the first and second blocks 3A, 3B. The fins 4A, 4B of the first and second blocks 3A, 3B extend groove walls of the lug grooves 2 to an outer side in a tire width direction from the plane X at circumferential edge parts 31A, 31B on one side of the blocks 3A, 3B. Projection amounts of the fins 4A, 4B with respect to the plane X gradually decrease from the circumferential edge parts 31A, 31B on the one side of the blocks 3A, 3B toward circumferential edge parts 32A, 32B on the other side.SELECTED DRAWING: Figure 2
