The invention relates to a pneumatic vehicle tyre, in particular for use in winter driving conditions, having a profiled tread with profiled blocks (4, 5), each of which has a rolling surface defining a reference level, by means of at least two cutouts (6, 7) which are parallel to one another and extend at an angle of < = 45 DEG to the axial direction of the tread. According to the invention, the cut-outs (7, 7) are divided into profile block sections (4a, 5a), which cut-outs have outlet openings with a width (b1) of 0.40 mm to 0.80 mm and cut-out walls (6a, 7a). According to the invention, at least one profile block section (4a, 5a) has a rib structure consisting of at least one rib (8) which extends along and laterally to the outlet opening of the cutout (6, 7) and over the extent of the cutout and which consists of a rib side edge (8a) which extends in the radial direction in the continuation of one cutout wall (6a, 7a), a platform (8b) which has a width (b2) of 0.10 mm to 0.40 mm, and a concave rounded rib (8b) which extends in the radial direction in the continuation of the cutout wall (6a, 7a) in the profile block section (4a, 5a). 5a) is formed by a rib side edge (8c) falling onto a reference level, and the rib has a height ([delta] h) of 0.20 mm to 0.70 mm with respect to the reference level.

    一种尤其用于在冬季行驶条件下使用的车辆充气轮胎,该车辆充气轮胎具有带胎纹块(4,5)的有胎纹的胎面,该胎面具有限定基准水平的滚动面,这些胎纹块分别借助至少两个彼此平行且与胎面的轴向方向成≤45°的角度延伸的切口(6,7)被分成胎纹块部段(4a,5a),这些切口具有宽度(b1)为0.40mm至0.80mm的出口开口和切口壁(6a,7a)。至少一个胎纹块部段(4a,5a)具有肋结构,该肋结构由至少一个沿着且侧向于切口(6,7)的出口开口且在切口的延伸范围之上延伸的肋(8)构成,该肋由在一个切口壁(6a,7a)的延续部分中沿径向方向延伸的肋侧缘(8a)、宽度(b2)为0.10mm至0.40mm的平台(8b)、和凹形倒圆的在胎纹块部段(4a,5a)处下降至基准水平上的肋侧缘(8c)形成,并且该肋相对于基准水平具有0.20mm至0.70mm的高度(δh)。
