Abstract: The tread comprises a plurality of blocks, each block being delimited by transverse or oblique grooves and circumferential grooves. Each block is provided with a sipe which has three branches. The branches have common ends. A first branch is oriented in a transverse or oblique direction. A second branch and a third branch each open when new into a transverse groove delimiting the block. The angle formed between the first and second branches is 100 to 125 degrees, and the angle formed between the first and the third branches is 100 to 125 degrees. After wear, each sipe represents between 45% and 70% of the total wearable thickness, such that the lengths of the three branches measured on the new tread surface, L1′, L2′, L3′ respectively, are shorter than the lengths L1, L2, L3 respectively measured on the tread surface when new.

Abstract: A pneumatic tire having enhanced on-ice braking performance achieved by further increasing the amount of water that can be sucked up into sipes. In the pneumatic tire, blocks (26) partitioned by circumferential grooves and lateral grooves are formed in the tread. A sipe (28) is formed in a block (26), and a fine structure (32) having a height in the range of from 1/50 of the sipe width t to less than 1/10 of the sipe width t is formed on a sipe wall surface. This reduces fluid friction coefficient of water relative to the sipe wall surface to a lower level than conventional products. As a result, when water staying on ice comes into contact with the sipe wall surface, the water is more easily sucked up into the sipe. The construction increases the amount of water that can be sucked up into the sipe (28) or the removal amount of water that stays on ice etc., and this enhances braking performance (friction characteristics) on ice.
