The invention relates to a pneumatic vehicle tire comprising a tread with shoulder-side blocks (5), which belong to shoulder block rows (6), and central blocks (4) between the shoulder-side blocks (5). Each of the shoulder-side blocks (5) and the central blocks (4) is provided with at least two sipes (7, 9) which extend substantially parallel to each other in plan view and at an angle of up to 35° relative to the axial direction and which have 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 sipes. Each of the blocks (4, 5) is provided with multiple micro grooves (8, 10, 10'), in particular at least four micro grooves, which extend substantially parallel to the sipes (7, 9) in plan view and have a width of 0.2 mm to 0.5 mm and a depth of 0.2 mm to 0.5 mm. At least two micro grooves (8, 10) run between at least two sipes (7, 9) in each block (4, 5). Furthermore, at least one respective micro groove (8, 10) runs in each block between the other sipes (7, 9). Only one single micro groove (8, 10') runs between at least one of the sipes (7, 9) running on the block edge side and the block edge region.
