PNEUMATIC TIRE

A pneumatic tire is provided which achieves a rigidity improvement in acute angle areas of blocks, thereby improving the durability and traction of the tire. A tire includes a tread (10). The tread (10) includes central blocks (70) defined by grooves (12). Each of the central blocks (70) has at least four central sipes (120) arranged in an arrangement direction. Each of the central sipes (120) has a wavy shape with amplitude in a tire surface view. Each of the central blocks (70) has acute angle regions (75) respectively disposed at both ends thereof in the arrangement direction. Each of the central sipes (120) includes first sipes (125) and second sipes (126). The first sipes (125) are respectively disposed at both the ends of the central block (70) in the arrangement direction and are respectively closest to the acute angle regions (75). The second sipes (126) are arranged between the first sipes (125). An interval (E) between one of the first sipe (125) and the second sipe (126) adjacent to said first sipe (125) is greater than an interval (D) between a pair of the second sipes (126) adjacent to each other in the arrangement direction.
