The invention relates to a pneumatic vehicle tyre having a tread with at least one profile rib (1, 2) delimited on both sides by a circumferential groove (4, 5), respectively, having a rib outer surface (6) located on the periphery of the tread, according to the invention, the profile ribs (1, 2) are formed in the circumferential direction of the profile ribs in the form of rib blocks (1a, 2a) with a plurality of transverse slots (7I, 7II) which run in particular parallel to one another in a top view and which each have two slot walls (9, 9 ') and a width (bE) of 0.4 mm to 1.2 mm, each rib block (1a, 2a) being provided with a chamfered recess (10) on the rib outer surface (6) adjoining one of the slot walls (9, 9') in the middle region of the profile ribs (1, 2), the recesses of the chamfered design are spaced apart from the circumferential grooves (4, 5) and extend longitudinally in a top view in the direction of extension of the slots (7I, 7II). According to the invention, a micro-cut (13), which is formed in the respective rib (1a, 2a) and which has a length (lME) measured in the circumferential direction, which is 40% to 70% of the circumferential length (lRB) of the associated rib (1a, 2a), merges into each cut (7I, 7II), opposite an end region of the chamfered recess (10), and the length (lME) of the respective rib (1a, 2a) is greater than the circumferential length (lRB) of the rib (1a, 2a), which is greater than the circumferential length (lRB) of the rib (1a, 2a). And the micro-cut groove has a width (bME) and a depth (tME) of 0.5 mm to 2.5 mm, respectively, and extends at an angle of up to +/-10 degrees to the circumferential direction in a top view.

    本发明涉及一种车辆充气轮胎,该车辆充气轮胎具有胎面,该胎面具有在两侧分别通过周向沟纹(4,5)界定的至少一个胎纹肋(1,2),该至少一个胎纹肋具有位于胎面周边的肋外表面(6),其中胎纹肋(1,2)在其周向上以多个横穿的、在俯视图中尤其彼此平行延伸的切槽(7I,7II)构造成肋块(1a,2a),这些切槽各自具有两个切槽壁(9,9')和0.4mm至1.2mm的宽度(bE),其中在胎纹肋(1,2)的中间区域中,每个肋块(1a,2a)在邻接切槽壁(9,9')之一处在肋外表面(6)上设有倒棱状设计的凹陷(10),该倒棱状设计的凹陷与周向沟纹(4,5)间隔开、在俯视图中在切槽(7I,7II)的延伸方向上纵向延伸。与倒棱状设计的凹陷(10)的一个端部区域相反,在相应的肋块(1a,2a)中形成的微切槽(13)汇入每个切槽(7I,7II)中,该微切槽具有沿周向方向测得的长度(lME),该长度是所属肋块(1a,2a)的周向长度(lRB)的40%至70%,并且该微切槽具有分别为0.5mm至2.5mm的宽度(bME)和深度(tME)并且在俯视图中与周向方向成高达±10°的角度延伸。
