Abstract: A pneumatic tire has a tread that is provided with a plurality of blocks comparted in a tire circumferential direction by a lateral groove. A sipe formed in each of the blocks has a narrow portion that is open in a tread surface, and a wide portion that is communicated with an inner side in a tire diametrical direction of the narrow portion and is widened than the narrow portion. The wide portion gradually increases a widening length in one side in a width direction and gradually decreases a widening length in other side in the width direction, from one end portion of the sipe toward other end portion, and accompanies an angle change at a time of appearing on the tread surface due to a progress of a wear.

Abstract: A pneumatic tire. In a block 18 formed on a tread surface, a sipe 24 which is twisted at a predetermined angle from a surface portion 28 toward a bottom portion 30 is provided. Due to ground contact pressure exerted on a contact patch area 26, small blocks 18a to 18d rotate, so that adjacent small blocks abut each other with a strong force. As a result, leaning of the small blocks 18a to 18d is suppressed, and a contact patch area area on the contact patch area 26 increases, so that performance on ice and snow improves. Moreover, due to rotation of the small blocks 18a to 18d, a torque (SAT) for restoring the small block to an original shape is generated, so that SAT generated by steel cords can be suppressed.

Abstract translation: 一种充气轮胎。在形成在胎面表面上的块18中，设置有从表面部28向底部30以预定角度扭转的刀槽花纹24。 由于施加在接触片区域26上的接地压力，小块18a至18d旋转，使得相邻的小块以强力彼此邻接。 结果，抑制了小块18a至18d的倾斜，并且接触片区域26上的接触片面积区域增加，使得在冰雪上的性能提高。 此外，由于小块18a至18d的旋转，产生用于将小块恢复为原始形状的扭矩（SAT），从而可以抑制由钢丝帘线产生的SAT。

Abstract: A tire includes a circumferential tread having a tread element disposed thereon, wherein the tread element includes a top surface that defines a first plane. The tire further includes at least one substantially helicoid-shaped sipe disposed in the tread element. The substantially helicoid-shaped sipe is defined by an opening in the top surface extending in a first direction in the first plane when the tire is new, and is further defined by a base extending in a second direction in a second plane parallel to the first plane. The second direction is disposed at an angle between 45° and 135° with respect to the first direction.

Abstract: A pneumatic vehicle tire which has fine slits in the tread. These slits are inclined relative to the circumferential direction of the tire. In order to increase the frictional connection to the roadway, to make the wear of the tread more uniform, and in addition to be able to use mechanically stiff plates for the associated vulcanization molds, the fine slits are twisted about an at least approximately radially extending twist axis. The fine slits preferably extend continuously from their roots into the tread surface region proper.
