The invention relates to a pneumatic vehicle tire having a profiled tread with at least one profiled strip (2), in particular a circumferential rib (2) or a row of profiled blocks, delimited by two circumferential grooves (1), having at least one groove (3) connecting the two circumferential grooves (1), the width B of the at least one groove being 0.4 mm to 1.2 mm, wherein the groove (3) has a vertical channel (20) and a horizontal channel (18) as local enlargement, the vertical channel (20) running radially inward from the opening (9) of the tread surface (5) into the horizontal channel (18) and being connected to the two circumferential grooves (1) by means of the horizontal channel. The wetland characteristics are further improved in such a way that the vertical channel (20) at least partially has a diameter D that decreases radially inward, wherein the diameter D is the maximum diameter of the circle (10) that can be inscribed into a cross-sectional area F of the vertical channel (20) oriented perpendicular to the radial direction rR.

    一种车辆充气轮胎,该车辆充气轮胎具有带胎纹的胎面,该带胎纹的胎面具有由两个周向沟纹(1)界定的至少一个胎纹带(2)、尤其是周向肋(2)或胎纹块列,该至少一个胎纹带具有连接这两个周向沟纹(1)的至少一个沟纹(3),该至少一个沟纹的宽度B为0.4mm至1.2mm,其中沟纹(3)具有竖直通道(20)和水平通道(18)作为局部扩大部,其中竖直通道(20)从胎面表面(5)的开口(9)径向向内延伸地汇入到水平通道(18)中并且藉由水平通道与这两个周向沟纹(1)相连接。以如下方式进一步改善湿地特性:竖直通道(20)至少部分地具有径向向内减小的直径D,其中直径D是能够内接到竖直通道(20)的与径向方向rR垂直定向的截面面积F中的圆(10)的最大直径。
