摘要： 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.
摘要翻译：通过进一步增加可被吸入刀槽花纹中的水量而实现的具有增强的冰上制动性能的充气轮胎。在充气轮胎中，在胎面中形成由周向槽和横向槽分隔的块（26）。在花纹块（26）上形成刀槽花纹（28），并且形成高度在刀槽花纹宽度t的1/50至小于刀槽花纹宽度t的1/10的范围内的精细结构（32）在刀槽花纹壁面上。这使水相对于刀槽花纹壁表面的流体摩擦系数降低到比常规产品更低的水平。结果，当冰上的水与刀槽花纹壁表面接触时，水更容易被吸入刀槽花纹中。该结构增加了可以吸入刀槽花纹（28）的水量。或停留在冰上的水的去除量等，并且这增强了冰上的制动性能（摩擦特性）。

摘要： 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.
摘要翻译：具有高牵引性能的充气轮胎。在胎面（12）的赤道（CL）上设置有中央周向槽（14），在中央周向槽（14）的两侧的胎肩周向槽（18）之间设置有第一横向槽（20）以比所述第一横向槽（20）更小的相对于所述轮胎的轴向的角度。每个第一横向槽20的一端和每个第二横向槽22的一端在肩部周向槽18处汇合，肩部横向槽23设置在每个肩部的外侧周向凹槽（18）。每个胎肩横向沟槽（23）从汇合部分朝向胎面端（12E）延伸并且相对于轮胎的轴向以比第一横向沟槽（20）的角度更小的角度形成。因为胎肩横向沟槽（23）相对于轮胎轴向的角度较小，所以轮胎的牵引性能增加。
