PROBLEM TO BE SOLVED: To improve driving performance or the like in an advancing direction while suitably securing side skid resistant performance or the like in a width direction by scheming an arrangement of circumferential grooves and circumferential sipes. SOLUTION: Blocks 7 and 8 partitioned by the circumferential grooves 4 and width direction grooves 5 are provided circumferentially aligned in a tread part 2, and circumferential sipes 11 and 12 are formed in the blocks 7 and 8. The circumferential groove 4 has a first groove part 4A, and a second groove part 4B circumferentially adjacent to the first groove 4A and formed offset in the width direction. Circumferential sipes 11B and 12B of the blocks 7 and 8 partitioned by the second groove 4B are formed offset with respect to circumferential sipes 11A and 12B of the blocks 7 and 8 partitioned by the first groove 4A in the same direction as the offset direction of the second groove 4B with respect to the first groove 44. |
