The invention relates to pneumatic vehicle tyres for passenger motor vehicles, in particular for use in winter driving conditions, comprising a tread having profile positives, in particular profile blocks (3, 4), and having grooves, in particular circumferential grooves (2), transverse grooves or diagonal grooves (1), bordering profile positives, wherein profile positives are provided in which a respective number of cuts (6) are formed running substantially parallel to one another, extending at an angle (γ) of 60° to 90° to a profile positive edge (8a, 8b) bordering the profile positive with a groove, and feeding into the groove (1) on the associated profile positive flank (7a, 7b), and wherein, on profile positive flanks (7a, 7b) of profile positives, in which the cuts (6) run at an angle (γ) of 60° to 90° to the associated profile positive edges (8a, 8b), substantially straight micro grooves (9) are formed which extend along the profile positive flanks (7a, 7b, 8a, 8b) at an acute angle (δ) of 20° to 40° to the profile positive edges (8a, 8b), which have a depth (t3) from 0.2 mm to 0.5 mm and a width (B) on the profile positive flank, corresponding to at least the depth (t3) thereof.
