The invention relates to a pneumatic vehicle tyre having a tread with blocks (1, 1 '), which in each case have a block outer surface (4) and at least one sipe (7), which extends in a top view at an angle of 0 DEG to 50 DEG to the axial direction and spans the respective block (1, 1'). The invention relates to a sipe (1, 1 '), which is divided into block segments (1a) and has a width (bE1) of 0.4 mm to 1.2 mm, a maximum depth (tE1) of 70% to 100% of the depth of the sipe, two sipe walls (9), and a sipe central region (F1) spaced apart according to the sipe walls (9), the spanning sipe (7) is produced to the maximum depth (tE1) at least in a sipe region extending over a portion of the sipe (7) in a top view and has a protrusion (7b), the projection is at a distance from the block outer surface (4) and is formed between a radially outer delimiting line (La) and a radially inner delimiting line (Li) as seen in a corresponding cross-section perpendicular to the sipe central region (F1). The radially outer delimiting line extends through the radially outermost point of the protrusion (7b) with respect to the sipe central region (F1) at a constant first depth determined in the radial direction, the radially inner delimiting line extends through a radially innermost point of the protrusion (7b) with respect to the sipe central region (F1) at a constant second depth determined in the radial direction. In each case, at least one additional sipe (8, 8 ') is formed in a block section (1a) of the pattern blocks (1, 1'), which is elongated in a top view and has a width (bE2) of 0.3 mm to 1.0 mm and a maximum depth (tE2), said additional sipe (8, 8 ') enclosing with the spanning sipe (7) complementary angles (alpha) which deviate from 90 DEG to 60 DEG, and the at least one additional sipe has a sipe end portion (8a, 8'a) in a region radially outside the projection (7b) of the spanning sipe (7), the point of the maximum depth (tE2) of the additional sipe (8, 8 ') being located radially inside the level of the radially outside delimiting line (La) of the projection (7b).

    本发明涉及一种车辆充气轮胎,该车辆充气轮胎具有胎面,该胎面具有花纹块(1,1'),这些花纹块在各自情况下具有块外表面(4)和至少一个刀槽花纹(7),该至少一个刀槽花纹在俯视图中以与轴向方向成0°至50°的角度延伸、跨越相应的花纹块(1,1')、分成块部段(1a)、并且具有:0.4mm至1.2mm的宽度(bE1)、花纹深度的70%至100%的最大深度(tE1)、两个刀槽花纹壁(9)、以及根据这些刀槽花纹壁(9)间隔开的刀槽花纹中心区域(F1),其中,跨越式刀槽花纹(7)至少在俯视图中在该刀槽花纹(7)的一部分上延伸的刀槽花纹区域中被制造到该最大深度(tE1)并具有突出部(7b),该突出部与该块外表面(4)相距一定距离并且如在垂直于该刀槽花纹中心区域(F1)的对应截面中看到的形成在径向外部界定线(La)与径向内部界定线(Li)之间,该径向外部界定线相对于该刀槽花纹中心区域(F1)以在径向方向上确定的恒定的第一深度延伸穿过该突出部(7b)的径向最外点,该径向内部界定线相对于该刀槽花纹中心区域(F1)以在该径向方向上确定的恒定的第二深度延伸穿过该突出部(7b)的径向最内点。在各自情况下,至少一个附加刀槽花纹(8,8')形成在这些花纹块(1,1')的块部段(1a)中,该至少一个附加刀槽花纹在俯视图中是长形的并且具有0.3mm至1.0mm的宽度(bE2)以及最大深度(tE2),所述附加刀槽花纹(8,8')与该跨越式刀槽花纹(7)围成互补角(α),这些互补角从90°偏离上至60°,并且该至少一个附加刀槽花纹在该跨越式刀槽花纹(7)的突出部(7b)的径向外部的区域中具有刀槽花纹端部部分(8a,8'a),其中,该附加刀槽花纹(8,8')的最大深度(tE2)的点位于该突出部(7b)的径向外部界定线(La)的水平的径向内部。
