The invention relates to a tyre comprising a tread comprising so-called elongated sipes (82) located in a tread block (20) and comprising:-a central portion (84) arranged between dimension points (94, 96) defining an elongate direction (Ei) of the elongated sipes (82); -an elongated portion (86, 88), said elongated portion (86, 88) being arranged between one of the dimension points (94, 96) and one of the blind ends (90, 92). The central portion (84) and the elongated portions (86, 88) are arranged such that, when moved along the elongated sipe (82) from the elongated portions (86, 88) towards the central portion (84), the direction of movement changes relative to the elongated direction (Ei) when passing through the dimensional points (94, 96) defining the elongated direction (Ei). The ratio between the curvilinear lengths of the elongated portions (86, 88) and the central portion (84) is strictly less than 1.0.

    本发明涉及一种轮胎,所述轮胎包括胎面,所述胎面包括所谓的延长刀槽(82),所述延长刀槽(82)位于胎面块状部(20)中并包括:‑中央部分(84),所述中央部分(84)布置在限定延长刀槽(82)的细长方向(Ei)的尺寸点(94、96)之间;‑延长部分(86、88),所述延长部分(86、88)布置在尺寸点(94、96)中的一个和盲端部(90、92)中的一个之间。中央部分(84)和延长部分(86、88)布置为使得当沿着延长刀槽(82)从延长部分(86、88)朝向中央部分(84)移动时,当穿过限定细长方向(Ei)的所述尺寸点(94、96)时,移动方向相对于细长方向(Ei)改变。延长部分(86、88)与中央部分(84)的曲线长度之间的比值严格小于1.0。
