The invention relates to a pneumatic vehicle tyre, comprising a tread having at least one profile rib (3) delimited on each side by a circumferential groove (4, 5), which profile rib is divided into rib blocks (3a) which lie one behind the other in the circumferential direction, at least one, in particular exactly one, micro-groove group (G1, G2, G3) being formed in each case in adjacent rib blocks (3a), the invention relates to a microgroove group (1) for a motor vehicle, comprising microgrooves (8, 8 ') having a width # imgabs0 # of 0.4 mm to 2.0 mm, which microgrooves extend parallel in the circumferential direction at an angle of at most 10 DEG, and which microgroove group is delimited in the circumferential direction by two boundary lines (1) extending in the axial direction, which boundary lines extend through microgroove ends that are farthest from one another in the circumferential direction. The profile ribs (3) are divided into rib blocks (3a) by cuts (7) leading into the circumferential grooves (4, 5); a micro-groove region (F) is formed by micro-groove groups (G1, G2, G3) formed by at least two successive rib blocks (3a); the pitch (aF) between successive microgroove regions (F) in the circumferential direction is 25% to 120% of the average circumference of the rib (3a); the rib (3a) does not contain microgrooves in a region between local microgroove regions (F).

    一种车辆充气轮胎,该车辆充气轮胎具有:胎面,该胎面带有在每一侧各由一条圆周沟纹(4,5)界定的至少一个胎纹肋(3),该胎纹肋被分成在周向方向上前后相继的肋块(3a),其中在彼此相邻的肋块(3a)中分别形成有至少一个、尤其恰好一个微沟纹组(G1,G2,G3),该微沟纹组由宽度#imgabs0#为0.4mm至2.0mm的微沟纹(8,8')构成,这些微沟纹平行地、在周向方向上以最大为10°的角度延伸,并且该微沟纹组在周向方向上由沿轴向方向延伸的两条边界线(l)界定,这些边界线延伸穿过在周向方向上彼此间隔最远的微沟纹端部。胎纹肋(3)通过汇入圆周沟纹(4,5)的切口(7)被分成肋块(3a);由至少两个前后相继的肋块(3a)形成的微沟纹组(Gl,G2,G3)构成微沟纹区域(F);在周向方向上前后相继的微沟纹区域(F)之间的间距(aF)为肋块(3a)的平均周长的25%至120%;肋块(3a)在局部的微沟纹区域(F)之间的区域中不含有微沟纹。
