PNEUMATIC VEHICLE TYRE

Pneumatic vehicle tyre of a radial design comprising a tread with profile positives (2) extending in the circumferential direction, which are separated from one another by at least one groove (1) running around in the circumferential direction, which grooves are delimited by two groove flanks (4) opposite each other and a curved groove base (5) connecting the groove flanks (4). Seen in cross section, the curvature of the groove base (5) increases from the lowest point of the groove base (5) to the groove flanks (4). It may thereby follow the path of an ellipse. 呈径向结构形式的车辆充气轮胎，该车辆充气轮胎具有个胎面，该胎面具有在圆周方向上延伸的多个凸胎纹(2)，这些凸胎纹通过在圆周方向上环绕的至少个沟纹(1)彼此分离，该沟纹由两个彼此对置的沟纹侧面(4)和个连接这些沟纹侧面(4)的弯曲的沟纹底(5)限制。在横截面中观察，该沟纹底(5)的曲率从该沟纹底(5)的最深点直至这些沟纹侧面(4)而增大。在此可以遵循个椭圆的走向。
