    • A tire tread of a vehicular tire has, in a peripheral tire direction, a plurality of tread block rows that are separated from one another by wave-shaped longitudinal grooves arranged essentially in the peripheral tire direction. The individual tread blocks within each individual tread block row are separated form one another by transverse grooves, whereby the transverse grooves are arranged such that in a left tread half as well as in a right tread half the transverse grooves are aligned with one another. The groove center lines of the transverse grooves at the outer rims of the tire tread are slanted relative to a tire axis at an angle of 3.degree. to 15.degree.. The groove center lines of the transverse grooves of the center tread block rows are slanted relative to the tire axis at an angle of 15.degree. to 50.degree. whereby the transverse grooves create a design of transversely arranged elongated S-shaped grooves.In order to provide a new tire tread which improves the concurrent properties of longevity, anti-skidding on wet surfaces, hydroplaning and noise reduction, it is suggested to provide the center tread block rows with alternating T-shaped and S-shaped tread blocks.
    • 车轮胎的轮胎胎面在周向轮胎方向上具有通过基本上沿周向轮胎方向布置的波浪形纵向槽彼此分离的多个胎面花纹块列。 每个单独的胎面花纹块排中的单个胎面花纹块通过横向槽彼此分开,由此横向槽被布置成使得在左胎面一半以及右胎面半部中横向槽彼此对准。 在轮胎胎面的外缘处的横向槽的槽中心线相对于轮胎轴线以3°〜15°的角度倾斜。 中心胎面花纹块列的横向槽的槽中心线相对于轮胎轴线以15°至50°的角度倾斜,由此横向槽形成横向布置的细长S形槽的设计。 为了提供新的轮胎胎面,其改善了长寿的同时性能,在湿表面上的防滑,滑水和降噪,建议为中间胎面花纹块排提供交替的T形和S形胎面花纹块。
