PROBLEM TO BE SOLVED: To provide a pneumatic tire allowing the improvement of on-ice performance and uneven wear resistance based on shapes and the arrangement of sipes. SOLUTION: In this pneumatic tire, a tread part has a block 1 having an acute angle 1B tapered toward acute-angled vertex C and a wide width 1A relatively wider than the acute angle part 1B. In the wide width 1A of the block 1, the plurality of sipes A are arranged to be formed into zigzag shapes on a tread surface while being extended in the tire width direction. In the acute angle part 1B of the block 1, at least a sipe B is arranged to be formed into a zigzag shape on the tread surface while being extended in the tire width direction. Each of an amplitude R2 and a period L2 of the sipe B on the tread surface is made smaller than each of an amplitude R1 and a period L1 of the sipe A on the tread surface.
