The invention relates to a pneumatic vehicle tire, comprising a shoulder-side profile strip (2), which has a groove (3), which has a groove wall (4) and a groove edge (6). An improved solution of target conflicts of wet properties, dry braking and wear regimes is achieved in that the groove (3) has a constant first groove width (111) in the axially outer section (110) of 0.4 mm to 1.0 mm, and a second groove width (111) in the axially outer section (110) of the groove (3) of 0.4 mm to 1.0 mm in the axially outer section (110) of the groove (3) of the groove (3) of the groove (3). The groove (3) has a likewise constant second groove width (131) of 0.6 mm to 1.2 mm in the middle section (130) and the inner section (150), which second groove width is at least 0.2 mm greater than the first groove width (111); the groove walls (4) end radially outside in the outer section (110) with respective groove edges (6); the groove (3) has, in each of the middle section (130) and the inner section (150), a groove enlargement (7) which extends the groove towards the tread surface (5) and which is connected radially externally to the groove wall (4), said groove enlargement ending radially externally with a groove edge (6); the groove edge (6) has a constant second edge distance (132) of 1.6 mm to 2.2 mm in the middle section (130), which is 0.5 mm to 1.5 mm less than a constant third edge distance (152) of 2.2 mm to 3.2 mm of the groove edge (6) in the inner section (150).

    一种车辆充气轮胎,该车辆充气轮胎具有胎肩侧的胎纹带(2),该胎肩侧的胎纹带具有沟纹(3),该沟纹具有沟纹壁(4)和沟纹边缘(6)。以如下方式实现湿地特性、干地制动和磨损形态的目标冲突的经改进的方案,即:沟纹(3)在轴向外部区段(110)中具有0.4mm至1.0mm的恒定的第一沟纹宽度(111);沟纹(3)在中间区段(130)和内部区段(150)中具有0.6mm至1.2mm的同样恒定的第二沟纹宽度(131),该第二沟纹宽度比第一沟纹宽度(111)大至少0.2mm;沟纹壁(4)在外部区段(110)中在径向外部以相应的沟纹边缘(6)结束;沟纹(3)在中间区段(130)和内部区段(150)中分别具有在径向外部连接至沟纹壁(4)的、将沟纹朝向胎面表面(5)扩展的沟纹扩大部(7),该沟纹扩大部在径向外部以沟纹边缘(6)结束;并且沟纹边缘(6)在中间区段(130)中具有1.6mm至2.2mm的恒定的第二边缘间距(132),该第二边缘间距比沟纹边缘(6)在内部区段(150)中的、2.2mm至3.2mm的恒定的第三边缘间距(152)小0.5mm至1.5mm。
