The invention relates to a pneumatic vehicle tire having a tread associated with the direction of travel, the tread having inclined grooves (4) which run in a V-shape relative to one another over the tread width and which communicate with one another, at least two grooves (5), which are inclined in a plan view counter to the inclined grooves (4), extend between the inclined grooves (4) adjoining in the circumferential direction and each have two groove flanks (5a, 5b) and a groove bottom (5c), the inclined grooves (4) and the grooves (5) defining shoulder-side profile blocks (2) belonging to the two shoulder-side profile block rows (1) and a middle profile block (3) located in the central tread region (Z), wherein grooves (5), which are inclined counter to the inclined groove (4), are provided, each having a plurality of projections (6) on the groove flanks (5a, 5b) thereof, the projections (6) lying on one groove flank (5b) following the projections (6) lying on the other groove flank (5a) alternately, as viewed over the extent of the associated groove (5), and wherein a groove bottom pattern (5d) extending along the projection (6) remains on the groove bottom (5c). According to the invention, the projections (6) each have the shape of a pyramid with exactly two triangular delimiting surfaces (6a) and radially outer tips (S) on the groove flanks (5a, 5b), at least three projections (6) adjoining one another being formed on each groove flank (5a, 5b) such that the groove bottom profile (5d) has a zigzag profile in a top view.

    本发明涉及一种具有与行驶方向相关联的胎面的车辆充气轮胎,该胎面具有在胎面宽度上相对于彼此呈V字形延伸的、彼此连通的斜沟纹(4),其中在每个胎面半部中,在周向方向上邻接的斜沟纹(4)之间延伸有在俯视图中与斜沟纹(4)反向倾斜的至少两个凹槽(5),这些凹槽分别具有两个凹槽侧面(5a,5b)和凹槽底部(5c),其中斜沟纹(4)和凹槽(5)界定属于两个胎肩侧胎纹块列(1)的胎肩侧胎纹块(2)和位于中央胎面区域(Z)的中间胎纹块(3),其中设置有与斜沟纹(4)反向倾斜的凹槽(5),这些凹槽在其凹槽侧面(5a,5b)上分别具有多个凸起(6),其中在其所属的凹槽(5)的延伸尺寸上观察,位于一个凹槽侧面(5b)上的凸起(6)交替地跟随位于另一个凹槽侧面(5a)上的凸起(6),并且其中在凹槽底部(5c)上保留有沿着凸起(6)延伸的凹槽底部纹路(5d)。凸起(6)分别具有角锥形的形状,该角锥形具有正好两个三角形界定面(6a)和位于凹槽侧面(5a,5b)上的径向外部尖端(S),其中在每个凹槽侧面(5a,5b)上形成彼此邻接的至少三个凸起(6),这些凸起使得凹槽底部纹路(5d)在俯视图中具有之字形走向。
