PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of developing excellent on-ice/snow performance and wet performance and enabling an increase in uneven abrasive resistance. SOLUTION: This pneumatic tire comprises, on a tread part 1, a plurality of blocks 4 defined by vertical grooves 2 and lateral grooves 3. Each block 4 comprises at least one sipe 5. The sipe 5 is formed to be opened to the vertical grooves 2 at at least one end part 5x, bent in a same direction continuously at three or more positions, and bent in a same direction continuously at three or more positions, The bent angles A of the bent parts 5a, 5b, and 5c from the start of bending to the end of bending come within 60°≤A≤120°, and a block piece 4a surrounded by the sipe 5 extends to at least the edge part of the block 4.
