The invention relates to a pneumatic tire for a vehicle, comprising a profiled strip (2) having a groove (3) with groove walls (4), to which groove enlargement (7) extending the groove (3) towards a tread surface (5) are connected radially outward, and the width A of the groove (3) is 0.4 mm to 1.2 mm. The target conflict between wet land characteristics, dry land braking and rolling noise is improved in such a way that the groove (3) is formed in the axial extension thereof by the following five sections (11, 12, 23): an edge section (12), which adjoins the respective defined circumferential groove (1) and has a first length (13), an inner section (11), which is arranged axially between the edge sections (12) and has a second length (13), and an outer section (23), which is arranged axially between the inner section (11) and has a second length (13). The inner section (11) has a second length (10) greater than the first length (13), and a transition section (23), respectively, between the inner section (11) and the two rim sections (12), the transition section having a third length (24) less than or equal to the first length (13); and in each of the edge sections (12), the groove edges (6) run parallel to each other and have a constant first distance B1 of 2.2 mm to 3.2 mm; in the inner section (11), the groove edges (6) run parallel to each other and have a constant second distance B2 of 1.6 mm to 2.2 mm; the first spacing B1 is correspondingly 0.5 mm to 1.5 mm larger than the second spacing B2; in each of the two transition sections (23), a third distance B3 of the groove edge (6) increases from the second distance B2 towards the first distance B1.

    一种具有车辆充气轮胎,该车辆充气轮胎具有胎纹带(2),该胎纹带具有带有沟纹壁(4)的沟纹(3),与这些沟纹壁径向向外地连接有将沟纹(3)朝向胎面表面(5)扩展的沟纹扩大部(7),并且沟纹(3)的宽度A为0.4mm至1.2mm。以如下方式改进湿地特性、干地制动与滚动噪声之间的目标冲突:沟纹(3)在其轴向延伸部中由以下五个区段(11,12,23)构成:·分别与相应界定的周向沟纹(1)邻接的边沿区段(12),该边沿区段具有第一长度(13),·轴向布置在边沿区段(12)之间的内部区段(11),该内部区段具有大于第一长度(13)的第二长度(10),·以及相应地处在内部区段(11)与这两个边沿区段(12)之间的过渡区段(23),该过渡区段具有小于或等于第一长度(13)的第三长度(24);并且在边沿区段(12)中的每个边沿区段中,沟纹边缘(6)彼此平行地延伸并且具有2.2mm至3.2mm的恒定的第一间距B1;在内部区段(11)中,沟纹边缘(6)彼此平行地延伸并且具有1.6mm至2.2mm的恒定的第二间距B2;第一间距B1相应地比第二间距B2大0.5mm至1.5mm;在这两个过渡区段(23)中的每个过渡区段中,沟纹边缘(6)的第三间距B3从第二间距B2朝向第一间距B1增加。
