    摘要： A pneumatic tire has a sipe is formed in a land portion of a tread surface. The sipe has a wide region in which a sipe width is made larger than a tread at position which is at a distance from the tread. The wide region is constructed by alternately providing a concave groove extending in a depth direction of the sipe in both sides of a sipe wall surface along a longitudinal direction of the sipe.

    摘要： A pneumatic tire has a tread pattern including a plurality of main grooves extending along a tire circumferential direction, and a shoulder land portion constructed by a rib or a block row formed in an outer side in a tire width direction of the main groove positioned in an outermost side. A circumferential sipe is provided in each of the shoulder land portions in both sides in the tire width direction. The number of the circumferential sipes provided in the shoulder land portion in a vehicle inner side is larger than the number of the circumferential sipes provided in the shoulder land portion in a vehicle outer side.

    摘要： An object of the present invention is to provide a pneumatic tire capable of ensuring both of the ice braking performance and the ice turning performance while increasing the dry steering stability performance. To achieve the above object, a sipe extending in a width direction of the tire is formed a land portion, the sipe having: pluralities of wide portions each having an inclined plane that begins from the tread surface of a road surface, and terminates in the half way of a sipe wall while inclining so that a sipe width decreases toward the groove bottom of the sipe, and a pair of side faces connecting the inclined plane and the sipe wall therebetween, wherein the pluralities of wide portions are located alternately on both sipe walls along a longitudinal direction of the sipe.

    摘要翻译： 本发明的目的是提供一种能够在提高干式转向稳定性的同时确保制冰性能和冰车转动性能的充气轮胎。 为了实现上述目的，在轮胎的宽度方向上延伸的刀槽花纹形成有陆部，刀槽花纹具有多个宽的部分，各自具有从路面的胎面表面开始的倾斜面，并且终止于 刀槽花纹壁的一半路径同时倾斜，使得刀槽花纹宽度朝向刀槽花纹的槽底部减小，并且一对侧面将斜面和刀槽花纹壁连接在其间，其中多个宽部分交替地位于两个刀槽花纹 沿着刀槽花纹的纵向方向的壁。
