TIRE

On a tread of tire, an inclined width direction groove (120), a plurality of zigzag sipes (160), an inclined width direction groove (130) and a plurality of zigzag sipes (170) are repeatedly formed in the tire circumferential direction. The inclined width direction groove (120) communicates with the circumferential direction groove (32), one end of the sipe portion (122) communicates with the narrow groove portion (121), and the other end of the sipe portion (122) terminates in the rib-like block (100) without communicating with the circumferential direction groove (31). The inclined width direction groove (130) communicates with the circumferential direction groove (31), one end of the sipe portion (132) communicates with the narrow groove portion (131), and the other end of the sipe portion (132) terminates in the rib-like block (100) without communicating with the circumferential direction groove (32).
