Abstract

To improve wet performance while maintaining rolling resistance performance, a tire 1 includes a plurality of zigzag circumferential grooves 3, a plurality of lateral grooves 4 connecting zigzag peak portions K, and a plurality of hexagonal blocks 5 formed by the circumferential grooves 3 and the lateral grooves 4. The circumferential grooves 3 include a pair of shoulder circumferential grooves 3A and at least one crown circumferential groove 3B. A groove width W2 of the crown circumferential groove 3B is smaller than a groove width W1 of each shoulder circumferential groove 3A. Each hexagonal block 5 is provided with a sipe 6 extending in a tire axial direction, and a wide groove portion 7 connected to an inner side in a tire radial direction of the sipe 6 and extending in the tire axial direction with a width larger than that of the sipe 6.
