A pneumatic vehicle tire having a tread with profiling and at least one circumferential groove which runs in encircling fashion in the circumferential direction and is formed to a profile depth. At least over part of the circumference the groove has a cross section perpendicularly to the circumferential direction made up of at least two groove portions adjoining one another in a radial direction. A first groove portion is symmetrical with respect to the radial direction. The width of said groove portion in the axial direction is less than 3 mm and does not vary by more than 10%. A second radially inner groove portion is made wider in the axial direction in comparison with the first groove portion. It has the largest cross-sectional area of all the groove portions. Its cross-sectional area is asymmetrical to the radial direction, extends on both sides of the radial direction and has an edge without corners in the bottom region of the circumferential groove.
