The invention relates to a pneumatic vehicle tyre having a tread (2) which has a pattern and has at least one circumferential groove (1) which extends in a circumferential manner in the circumferential direction of the pneumatic vehicle tyre and is formed to a pattern depth PT, the at least one circumferential groove has a first cross-section perpendicular to the circumferential direction and a second cross-section perpendicular to the circumferential direction in an alternating manner over the entire tire circumference and over a partial section (21, 24) of the circumference of the vehicle pneumatic tire. The invention relates to a pneumatic vehicle tire having a first cross-section consisting of at least two groove portions adjoining one another in a first radial direction R1 of the pneumatic vehicle tire, a first groove portion (3) which is symmetrical with respect to the first radial direction R1 and which has a width BV in an axial direction A of the pneumatic vehicle tire, and a radially inner second groove portion (4), 1 is less than 3 mm and varies by no more than 10%, and a radially inner second groove portion (3) which extends in the axial direction A with respect to the first groove portion (3) and has the largest cross-sectional area in all groove portions. The second cross-section is composed of at least two groove portions which adjoin each other in a second radial direction R2 of the vehicle pneumatic tire and are symmetrical with respect to the radial direction R2, a first groove portion (33) which widens outward, and an inner second groove portion (34) which is narrower with respect to the first groove portion, the width BY of which is greater than the width BY of the first groove portion, the width BY of which is greater than the width BY of the second groove portion, and the width BY of which is greater than the width BY of the second groove portion. 2 varies by no more than 10% in the axial direction A of the vehicle pneumatic tire, and the width of the second groove portion on the inner side is less than 40% of the width BY, O of the second cross-section in the axial direction A on the surface of the tread when the vehicle pneumatic tire is new. The second groove portion (34) of the second cross-section extends in the radial direction R2 over at least 50% of the height H2V of the second groove portion (4) of the first cross-section in the radial direction R1, and the second groove portion of the second cross-section is at a distance from the surface of the tread (2) over at least 50% of the height H2Y of the second groove portion of the second cross-section in the radial direction R2, the second groove portion (4) is located in the first cross-section at the distance.

    一种车辆充气轮胎,该车辆充气轮胎具有胎面(2),该胎面具有花纹并且具有至少一个周向沟纹(1),该至少一个周向沟纹在车辆充气轮胎的周向方向上以环绕方式延伸并且形成至花纹深度PT,并且该至少一个周向沟纹具有在整个轮胎圆周上、在车辆充气轮胎的圆周的部分区段(21,24)上呈交替方式的垂直于周向方向的第一截面和垂直于周向方向的第二截面。该第一截面由在车辆充气轮胎的第一径向方向R1上彼此邻接的至少两个沟纹部分、第一沟纹部分(3)和径向内侧的第二沟纹部分(4)构成,该第一沟纹部分关于第一径向方向R1对称并且该第一沟纹部分沿车辆充气轮胎的轴向方向A上的宽度BV,1小于3mm并且变化不大于10%,该径向内侧的第二沟纹部分相对于第一沟纹部分(3)在轴向方向A上延伸并且具有所有沟纹部分中的最大截面面积。第二截面由沿车辆充气轮胎的第二径向方向R2彼此邻接并且关于径向方向R2对称的至少两个沟纹部分、向外变宽的第一沟纹部分(33)和相对于第一沟纹部分变窄的内侧的第二沟纹部分(34)构成,该内侧的第二沟纹部分的宽度BY,2沿车辆充气轮胎的轴向方向A变化不大于10%,并且该内侧的第二沟纹部分的宽度小于当车辆充气轮胎是新的时第二截面在胎面的表面上的在轴向方向A上的宽度BY,O的40%。第二截面的第二沟纹部分(34)在此在径向方向R2上在第一截面的第二沟纹部分(4)在径向方向R1上的高度H2V的至少50%上延伸,并且在第二截面的第二沟纹部分在径向方向R2上的高度H2Y的至少50%上,第二截面的第二沟纹部分距该胎面(2)的表面一定距离,第二沟纹部分(4)在该距离处位于第一截面中。
