The invention relates to vehicle pneumatic tyres comprising a profiled tread with studs (1, 2), which are arranged in stud tracks (SP) running around the circumference of the tread, wherein each stud (1, 2) has a stud body (3, 4) anchored in the rubber material of the tread and a stud pin (5) protruding beyond the periphery of the tread, wherein studs (1) of a first type and studs (2) of a second type are anchored in the tread, which differ from one another in terms of the configuration of their stud body (3, 4), wherein the stud bodies (3, 4) each have a base flange (6, 7) and an upper flange (8, 9) and a central vertical axis including their centre of gravity, and wherein the studs (1) of the first type are positioned preferably mainly in lateral regions of the tread and the studs (2) of the second type are positioned preferably mainly in the central tread region. The upper flange (8) of the studs (1) of the first type has a single plane of symmetry (S1) passing through the vertical axis (a) and running at a < 45° angle to the axial direction, and the upper flange of the studs (1') of the second type have a single plane of symmetry (S2) passing through the vertical axis (a) and running at a < 45° angle to the circumferential direction, wherein the upper flanges (8, 9) each have different size extensions determined along the planes of symmetry (S1, S2) and starting from the vertical axis (a).
