<p>Provided is a pneumatic tire, wherein first sipes extending in the axial direction of the tire while having an amplitude and extending in the depth direction while having an amplitude at least partially, and second sipes extending in the axial direction of the tire while having an amplitude and extending linearly in the depth direction without having an amplitude are arranged in a center block alternately in the circumferential direction of the tire, so that small blocks tilt appropriately to secure performance on the ice. On the other hand, stiffness distribution in the circumferential direction is made uniform in the block, and partial abrasion due to uneven stiffness distribution can be eliminated. Furthermore, mold release property is secured, because the blade of a mold forming the sipe extending in the depth direction while having an amplitude does not take the shape of a crank.</p> |
