The invention relates to a tyre (1) having a tread (10) distributed with one to three tread patterns (MA, MB, LC) on a circle of the wheel. Each tread pattern comprises a first portion and a second portion located on either side of the equatorial plane (C). Each portion of each tread pattern comprises at least one main sipe (85) having a curvature of the portion and substantially parallel to an edge of the portion, said main sipe (85) continuously extending from a first axial edge (24G, 24D) of a first side of the equatorial plane (C) to a connection point (90) in a main cut-out (80) located on a second side of the equatorial plane (C), the main cut-out (80) extends to a second edge (24G, 24D) of the tread (10); the axial width of the main grooves (85) is 52% to 63% of the axial width of the tread (10).
本发明涉及一种轮胎(1),所述轮胎(1)具有胎面(10),所述胎面(10)在车轮的一圈上分布有一种至三种胎面花纹(MA、MB、LC)。每种胎面花纹包括第一部分和第二部分,所述第一部分和第二部分位于赤道平面(C)的两侧。每种胎面花纹的每个部分包括至少一个主刀槽(85),所述主刀槽(85)具有该部分的曲率,且基本上平行于该部分的边缘,所述主刀槽(85)从赤道平面(C)的第一侧的第一轴向边缘(24G、24D)连续延伸至位于赤道平面(C)的第二侧的主切口(80)中的连接点(90),所述主切口(80)延伸至胎面(10)的第二边缘(24G、24D);所述主刀槽(85)的轴向宽度占胎面(10)的轴向宽度的52%至63%。
