    Abstract: A unidirectional pneumatic vehicle tire has a symmetric radial carcass and a symmetric package of belt plies placed on the carcass. The tire tread of an asymmetric tread design has at least three longitudinal grooves having a depth of 12 mm to 18 mm. The tire tread has an axially outer wide tread rib, positioned, when mounted on a vehicle, so as to face outwardly relative to the vehicle. The wide tread rib has a width of 25% to 40% of the width of the tire tread when measured at half the depth of an axially outer one of the longitudinal grooves positioned adjacent to the wide tread rib. The wide tread rib is free of any tread voids having a main direction of extension and is selected from the group consisting of longitudinal grooves, longitudinal sipes, transverse grooves, transverse sipes, diagonal grooves, and diagonal sipes. The wide tread rib has tread voids having in a top view of the tire tread a substantially round contour. The tread voids are arranged in 1 to 4 tracks in a circumferential direction of the tire tread, wherein each one of the tracks comprises 100 to 150 of the tread voids.

    Abstract translation: 单向气动车辆轮胎具有对称的径向胎体和放置在胎体上的带束层的对称包装。 不对称胎面设计的轮胎胎面具有至少三个深度为12mm至18mm的纵向槽。 轮胎胎面具有轴向外部宽的胎面肋,当安装在车辆上时,其被定位成相对于车辆面向外。 当在与宽胎面肋相邻的纵向槽的轴向外部一个的深度的一半测量时,宽的胎面肋具有轮胎胎面宽度的25%至40%的宽度。 宽的胎面肋没有任何具有主要延伸方向的胎面空隙,并且选自由纵向槽,纵向刀槽花纹,横向槽,横向刀槽花纹,对角槽和对角线槽组成的组。 宽的胎面肋具有在轮胎胎面的顶视图中具有基本圆形轮廓的胎面空隙。 胎面空隙在轮胎胎面的圆周方向上布置在1至4个轨道中,其中每个轨道包括100至150个胎面孔隙。
