ABSTRACT:
A wheel tread part2of a tread is constituted of a longitudinal main groove3formed in a circumferential direction via a center of a width direction, a plurality of longitudinal subgrooves4formed on both side parts of the longitudinal main groove3in the circumferential direction, and a plurality of traverse grooves5formed in a width direction to intersect the longitudinal main and subgrooves3, 4, and divided into a plurality of blocks6. Each of the plurality of blocks6is provided with a one-end-open sipe9, 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.
