Abstract: It is an object of the present invention to improve the running performance on snowy and icy roads, and for this purpose, blocks provided with sipes are formed at a tread portion. The sipes include an open top end that opens at a block surface and a bottom, and a configuration of the sipes in a plane parallel with the block surface comprises a zigzag part extending in the length direction of the sipes. The zigzag part displaces upon turning back to one side and to the other side in a length direction of the sipes in the course from the open top end to the bottom. At least one block includes a first sipe and a second sipe which depths of the turn-back points of displacement from the open top end and/or positions of the turn-back points of displacement in the length direction differ from each other.

Abstract: A wheel tread part 2 of a tread is constituted of a longitudinal main groove 3 formed in a circumferential direction via a center of a width direction, a plurality of longitudinal subgrooves 4 formed on both side parts of the longitudinal main groove 3 in the circumferential direction, and a plurality of traverse grooves 5 formed in a width direction to intersect the longitudinal main and subgrooves 3, 4, and divided into a plurality of blocks 6. Each of the plurality of blocks 6 is provided with a one-end-open sipe 9, and formed so that rigidity in the width direction can be higher in an end a of a center side region compared with an end b of a shoulder side region. Since the rigidity of the end a of the center side region is higher, a reaction force is generated in accordance with a steering angle from the start of changing the same.
