A pneumatic tire including a closed sipe in a land portion 3 formed in a tread surface, provided with at least three cuts extending in a radiation direction from an imaginary axis that extends in a depth direction of the land portion, and that terminate in the land portion. The cuts are provided with a spiral-like twist in the depth direction, centered on the imaginary axis, and a twist angle thereof is not less than 10° and not more than 135°. Additionally, a length in the radiation direction of the cuts or a width of the cuts is formed larger at a tread surface side than at a bottom surface side. |
