Abstract:
A pneumatic tire including a closed sipe 5 formed in a tread surface 1 that includes a small hole 2 extending along a tire radial direction and a plurality of cuts 4 extending in a radiation direction from the small hole 2 and that terminating in a land portion 3. A diameter of an inscribed circle of the small hole 2 is greater than a thickness of the cuts 4. The cuts 4 are provided with a twist in a depth direction centered on the small hole 2, and a twist angle θ from a top surface to a bottom surface of the land portion 3 is not less than 10° and less than 135°.
