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.

Abstract: A pneumatic tire exhibiting high traction performance. A center circumferential groove (14) is provided on the equator (CL) of the tread (12), and between shoulder circumferential grooves (18) on both sides of the center circumferential groove (14) are arranged first lateral grooves (20) formed at a smaller angle relative to the axial direction of the tire than the first lateral groove (20). One end of each first lateral groove (20) and one end of each second lateral groove (22) are made to merge at a shoulder circumferential groove (18), and shoulder lateral grooves (23) are arranged on the outer side of each shoulder circumferential groove (18). Each shoulder lateral groove (23) extends from the merging portion toward a tread end (12E) and is formed at a smaller angle relative to the axial direction of the tire than that of the first lateral groove (20). Because the angle of the shoulder lateral grooves (23) relative to the axial direction of the tire is less, traction performance of the tire increases.

Abstract translation: 通过进一步增加可以吸入刀槽花纹的水量，实现具有增强的制冰性能的充气轮胎。 在充气轮胎中，在胎面中形成有由周向槽和横向槽隔开的块（26）。 刀槽花纹（28）形成在块（26）中，并且形成具有在刀槽花纹宽度t的1/50的范围内的高度在小刀刀花纹宽度t的1/10之间的精细结构（32） 在刀槽砖墙面上。 这将水相对于刀槽花纹壁表面的流体摩擦系数降低到比传统产品更低的水平。 结果，当水停留在冰上与刀槽花纹壁表面接触时，水更容易被吸入到刀槽花纹中。 该结构增加了可以吸入到刀槽花纹（28）中的水量或停留在冰上的水的去除量等，这增加了冰上的制动性能（摩擦特性）。
