The invention relates to a pneumatic vehicle tire having a tread with shoulder-side blocks (8) belonging to a row (2, 6) of shoulder blocks and intermediate blocks (8) between the shoulder-side blocks (8), each of which, in a top view, has at least one of the shoulder-side blocks (8) and the intermediate blocks (8). At least some of the blocks (8) on the shoulder side and/or at least some of the blocks (8) located in the middle are provided with at least one cut-out (10) extending at an angle of up to 35 DEG to the axial direction (AR), which cut-out has a width of 0.4 mm to 0.8 mm and has a depth of at least 50% of the profile depth at the deepest position thereof, and in which micro-grooves (13-20) are arranged, wherein the microgrooves (13-20) have a width of 0.2 mm to 0.6 mm and a depth of 0.2 mm to 0.9 mm. At least one of the blocks (8) has a microgroove element (12) consisting of microgrooves (13-20) arranged in a dendritic manner like snow crystals, the microgroove element (12) consisting of at least four microgrooves (13-16) which face a center point (21) of the microgroove element (12) in a star-shaped manner.

    本发明涉及一种车辆充气轮胎,该车辆充气轮胎具有胎面,该胎面具有属于胎肩块列(2,6)的胎肩侧的块(8)和胎肩侧的块(8)之间的位于中间的块(8),其中,各自在俯视图中,胎肩侧的块(8)中的至少一些块和/或位于中间的块(8)中的至少一些块设有与轴向方向(AR)成最大达35°角度延伸的至少一个切口(10),该至少一个切口具有0.4mm至0.8mm的宽度并且在其最深位置处所具有的深度为胎纹深度的至少50%,并且其中布置有微沟纹(13‑20),其中微沟纹(13‑20)具有0.2mm至0.6mm的宽度和0.2mm至0.9mm的深度。这些块(8)中的至少一个块具有由像雪晶般呈树突状布置的微沟纹(13‑20)构成的微沟纹元素(12),其中微沟纹元素(12)由至少四个微沟纹(13‑16)组成,这些微沟纹以星形的方式朝向微沟纹元素(12)的中心点(21)。
