Zusammenfassung:The invention relates to a pneumatic vehicle tire comprising a tread with shoulder-side blocks (7) and central blocks (7). At least the shoulder-side blocks are mutually spaced by lateral grooves (6), and the shoulder-side blocks (7) have inlet and outlet edges (8), wherein each of the blocks (7) is provided with at least two substantially parallel recesses (10) in plan view, said recesses extending at an angle of up to 45° relative to the axial direction and having a width of 0.4 mm to 0.8 mm and a depth of at least 50% of the profile depth at the deepest point of the recesses. The blocks (7) additionally have micro grooves (11) which are arranged substantially parallel to the recesses (10) and/or laterally to the recesses (10), and the micro grooves (11) have a width of 0.2 mm to 0.7 mm and a depth of 0.2 mm to 0.7 mm. At least one of the shoulder-side blocks is equipped with at least one micro groove (11), the extension of which forms an angle ɑ of 0° to 15° relative to the circumferential direction (uR), and a funnel-shaped extension (12) is formed at both ends of said micro groove (11) in the region of the inlet and outlet edge (8), said extension opening into the respective lateral grooves (6) delimiting said block (7).
