PROBLEM TO BE SOLVED: To provide a tire further improving on-snow/ice performance, while maintaining the rigidity of a block. SOLUTION: Width directional sipes 100 and 102 extending in a zigzag shape along the tread width direction TW are formed in the blocks 24 and 26 partitioned by peripheral directional grooves 40, 42, 44 and 46 extending along the tire circumferential direction TC and peripheral grooves 60, 62, 64 and 66 extending along the tread width direction TW. The blocks 24 and 26 include an inside block 20 arranged inside when installed in a vehicle and an outside block 28 arranged outside when installed in the vehicle. The inside block 20 is formed with a first peripheral directional sipe 50 extending along the tire circumferential direction TC, shallower in the groove depth than the width directional sipe 100 and shallow in the groove depth on the central side of the inside block 20. The outside block 28 is formed with a second peripheral directional sipe 52 extending along the tire circumferential direction TC, shallower in the groove depth than the width directional sipe 100 and shallow in the groove depth on both end sides of the outside block 28.
