摘要： Provided is a pneumatic tire whose braking performance on ice and partial-wear resistance can be improved. Sipes 11X provided in a rib 5 on a tire equatorial plane TE are formed in such a three-dimensional shape that the amount at which the rib 5 collapses due to an external force is smaller in the tire rotational direction than in a direction opposite to the tire rotational direction. In each block 10 in each shoulder region 1S, sipes 11Ma in a block tread-in side portion 10A are each formed in such a three-dimensional shape that the amount at which the block 10, if entirely provided with the sipes 11Ma, collapses due to an external force will be smaller in the tire rotational direction than in the direction opposite to the tire rotational direction. Sipes 11Mb in a block kick-out side portion 10B are each formed in such a three-dimensional shape that the amount at which the block 10, if entirely provided with the sipes 11Mb, collapses due to an external force will be smaller in the direction opposite to the tire rotational direction than in the tire rotational direction.

摘要： A pneumatic tire for use on iced and snowed road surfaces has a tread surface. The tread surface has a plurality of main grooves extending in a circumferential direction of the tire and a plurality of lateral grooves extending in a width direction of the tire. Blocks are defined by the main grooves and the lateral grooves. The blocks have a ground contact face which has a plurality of pairs of sipes comprising a left sipe and a right sipe extending in the tire width direction. The plurality of pairs of sipes are placed in a predetermined interval in the tire circumferential direction. Each of the left and right sipes of each pair extends from a width-directional center portion of the ground contact face of the block toward each way of the tire width direction so as to open its outer end to each side face of the block.
