    • A tire tread band for medium/heavy duty motor-vehicles having circumferential grooves confining three pairs of respectively center, intermediate and shoulder ribs. Respective tread blocks are defined along the center and intermediate ribs and they are confined by transverse cuts. The center cuts impart a cusp-shaped end conformation and a hollow-shaped end conformation to the respective blocks, and the shapes of said end portions mutually match. The intermediate cuts run in the linear extension of the center cuts to give the respective blocks a rhomboidal configuration. The tire can be alternately associated with a driving axle or a driven axle, by merely reversing its direction of rotation, so that the following results are selectively achieved: an increase in the traction capability by the intermediate blocks or an increase in the directional capability as a result of the mutual wedging between the center blocks at the ground-contacting area.
    • 一种用于中型/重型机动车辆的轮胎胎面带,其具有围绕三对分别的中心,中间和肩部肋骨的周向槽。 相应的胎面花纹块沿中心和中间肋条定义,并且它们被横向切割限制。 中心切口对相应的块赋予尖端形状的端部构造和中空形端部构造,并且所述端部部分的形状相互匹配。 中间切口在中心切口的线性延伸中运行,以使相应的块成为菱形配置。 轮胎可以通过仅使其旋转方向反转来交替地与驱动轴或从动轴相关联,使得选择性地实现以下结果:中间块的牵引能力的增加或定向能力的增加作为 这是在地面接触区域的中心块之间相互楔入的结果。
