PROBLEM TO BE SOLVED: To maintain drainage performance at the wet time and reduce noise generated in a frequency area near 1kHz and further reduce noise in a low frequency area. SOLUTION: A plurality of blocks 4 positioned at outermost parts to the grounding edges (e), (e) of a tire tread face 1 and surrounded by lateral grooves 3 (3a-3e) and inclined grooves 2 connected to the lateral grooves 3, with the grounding edges (e), (e) as boundaries are provided in a circumferential direction of a tire. The area ratio L/S of the surface area L of each L-block 4a long in a tire width direction and the surface area S of each S-block 4b short in the tire width direction, adjacent to each other on the same side of the inclined groove 2 on the basis of the grounding edges (e), (e) out of the blocks 4 is to be 1.0-1.2. |
