    Abstract: A pneumatic tire includes main grooves 1 extending substantially in a circumferential direction R of the tire, transverse grooves 2 connecting adjacent main grooves, and blocks 3 formed by adjacent main grooves and adjacent transverse grooves. Each block 3 has an acute corner portion 3a and an obtuse corner portion 3b and also has a groove side extending along the main groove 1 between the acute corner portion 3a and the obtuse corner portion 3b. An inclination angle a1 of the groove side increases from the obtuse corner portion 3b toward the acute corner portion 3a. An extending direction 1a of the main groove 1 at a tread surface level is inclined toward one side of the main groove 1 with respect to the circumferential direction R of the tire, while an extending direction of the main groove 1 at a groove bottom level is inclined toward the other side.

    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 translation: 充气轮胎具有通过横向槽设置有沿轮胎周向隔开的多个块的胎面。 在每个块体中形成的刀槽花纹具有在胎面表面上敞开的狭窄部分，以及与窄部分的轮胎径向内侧相连并且比窄部分变宽的宽部分。 宽幅部逐渐增加宽度方向的一侧的长度变宽，并且在宽度方向的另一侧，从刀槽花纹的一端向另一端部逐渐减小加宽长度，伴随着 由于磨损的进展而出现在胎面上。
