Disclosed is a vehicle pneumatic tire, in particular a utility vehicle tire, having a tread (2) having a profile form and having at least one circumferential groove (1) which extends in a circumferential manner in the circumferential direction of the vehicle pneumatic tire and is formed to a profile depth PT. At least on a part of the outer circumference of the vehicle pneumatic tire, the at least one circumferential groove (1) has a cross-section perpendicular to the circumferential direction formed by at least two groove portions adjacent to each other in the radial direction R of the vehicle pneumatic tire. The first groove portion (4) is symmetrical with respect to the radial direction R of the vehicle pneumatic tire. The width of the groove portion in the axial direction A of the vehicle pneumatic tire is less than 3 mm and does not vary by more than 10%. The second radially inner groove portion (5) is wider in the axial direction A than the first groove portion (4). The second radially inner groove portion (5) has the largest cross-sectional area among all groove portions. The cross-sectional area of the second radially inner groove portion (5) is asymmetric with respect to the radial direction R, extends on both sides of the radial direction R and has a corner-free edge in the bottom region of the circumferential groove (1).
披露了一种车辆充气轮胎、特别是多用途车辆轮胎,该车辆充气轮胎具有胎面(2),该胎面具有一种轮廓形式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被形成至轮廓深度PT。至少在车辆充气轮胎的外周的一部分上,至少一个周向沟纹(1)具有的垂直于周向方向的截面由在车辆充气轮胎的径向方向R上彼此邻接的至少两个沟纹部分构成。第一沟纹部分(4)关于车辆充气轮胎的径向方向R是对称的。所述沟纹部分在车辆充气轮胎的轴向方向A上的宽度小于3mm且变化不超过10%。与第一沟纹部分(4)相比,第二径向内侧沟纹部分(5)在轴向方向A上更宽。第二径向内侧沟纹部分(5)具有所有沟纹部分中最大的截面积。第二径向内侧沟纹部分(5)的截面积关于径向方向R是不对称的、在径向方向R的两侧延伸并且在周向沟纹(1)的底部区域中具有无拐角的边缘。
