PROBLEM TO BE SOLVED: To suppress the partial wear at the part where the sipe interval is small, and to improve the ice braking performance and ice turning performance. SOLUTION: In this pneumatic tire, a block 1 has a first sipe 2 extending in the tire width direction A and a second sipe 3 extending in the tire width direction A at an angle different from that of the first sipe 2 formed therein, and the first sipe 2 and the second sipe 3 are arranged to be adjacent in the tire circumferential direction R. At the side where a spaced distance d between the adjacent first sipe 2 and the second sipe 3 is small, at least either the first sipe 2 or the second sipe 3 is folded to enlarge the spaced distance d.
