摘要： Land portions that are partitioned by plural circumferential direction grooves are formed to a tread 12. The land portions are partitioned into plural block portions by plural tire width direction grooves extending along the tire width direction. Each block portion includes a recessed portion and a protrusion portion in plan view, and a block height of the protrusion portion is higher than a block height of the respective recessed portion positioned across the tire width direction groove.

摘要： A pneumatic tire comprising, in a tread, blocks partitioned by a plurality of circumferential grooves (3) extending in a tire circumferential direction and a plurality of width grooves (5) extending in a tread width direction. Circumferential sipes extending in a tire circumferential direction are formed in the blocks. An inner side circumferential sipe extends linearly in a tire diameter direction, and an outer side circumferential sipe extends in a zigzag pattern in a tire diameter direction. Accordingly, steering performance, especially cornering performance can be enhanced regardless of road surface conditions.
摘要翻译：本发明提供一种充气轮胎，该充气轮胎在胎面中具有由沿轮胎周向延伸的多个周向槽（3）和沿胎面宽度方向延伸的多个宽度槽（5）分隔的块体。在花纹块中形成沿轮胎周向延伸的周向刀槽花纹。内侧周向刀槽花纹在轮胎直径方向上直线状地延伸，外侧周向刀槽花纹在轮胎径向上以锯齿状延伸。因此，无论路面状况如何，都可以提高转向性能，特别是转弯性能。

摘要： The present invention is intended to provide a studless tire capable of enhancing straight-running stability with a low tread rigidity.
In a section of a studless tire 10 passing a central axis line under a condition where the tire is mounted on a predetermined rim 11 and a predetermined inner pressure is charged therein, assuming that a distance A is measured from a position where a bladder ring is divided to a position where a maximum tire width is obtained along the tire radial direction and a distance B is measured from the position where the bladder ring is divided to a position where a tread ring is divide along the tire radial direction, a side-shape coefficient of the tire defined as a ratio A/B in a state where the tire is installed on a vehicle is between 0.52 and 0.55 in a widthwise half portion disposed at a widthwise outer side of the vehicle and between 0.45 and 0.50 in a widthwise half portion disposed at a widthwise inner side of the vehicle, or between 0.5 and 0.55 in a widthwise half portion disposed at the vehicle installation outer side and between 0.45 and 0.48 in a widthwise half portion disposed at the vehicle installation inner side.
摘要翻译：本发明旨在提供一种能够以较低的胎面刚度提高直线运行稳定性的无钉防滑轮胎。在将轮胎安装在预定轮辋11上并将预定的内部压力装入其中的条件下穿过中心轴线的无钉防滑轮胎10的一部分中，假定从气囊环的位置测量距离A 被划分为沿着轮胎径向获得最大轮胎宽度的位置，并且从气囊分隔的位置到胎面环沿着轮胎径向划分的位置测量距离B，侧面形状在轮胎安装在车辆上的状态下被限定为比例A / B的轮胎的系数在设置在车辆的宽度方向外侧的宽度方向半部分的0.52和0.55之间，宽度方向上为0.45-0.50 设置在车辆的宽度方向内侧的部分，或设置在车辆安装外侧的宽度方向半部分在0.5和0.55之间，并且在宽度方向半部分设置在0.45和0.48之间在车辆安装内侧。

摘要： The present invention provides a pneumatic radial tire which is, by effectively suppressing collapse-deformation of a relatively large magnitude in sectioned portions of each block, which sections are demarcated by sipes, and also effectively preventing the sipe from making narrowing-deformation, excellent in not only driving performance and braking performance on an icy or snowy road but also driving stability on a general road. The tire characteristically includes: a tread having a contact surface 1; plural circumferential grooves 2; plural lateral grooves 3; blocks 4 demarcated by the circumferential grooves and the lateral grooves in the contact surface of the tread; and plural sipes 5 provided in the blocks 4, wherein the bottom portion of each sipe 5 is provided with at least one upward-protruding projection 7 for integrally connecting respective facing groove walls of the sipe 5.

摘要： A tread 12 is formed with land portions that are partitioned by plural circumferential direction grooves. The land portions are partitioned into plural block portions by plural tire width direction grooves extending along the tire width direction. The block portions include recessed portions and protrusion portions in plan view, and the height of the protrusion portions is higher than the height of the recessed portions that are formed by partitioning along the same tire width direction groove.
