The tyre (1) comprises at least one block (8) on which at least one complex-type sipe (10) is obtained, said complex-type sipe (10) dividing the block (8) into two parts (11, 2) comprising a first surface (13) and a second surface (14) facing each other. The first surface (13) extends between a set of first and second longitudinal sections (17, 18) having first and second radial contours (20, 21), respectively, symmetrical to each other, each comprising a coupling portion between two block portions (11, 12), the first and second radial contours (20, 21) being arranged in the first and second longitudinal sections (17, 18) in the first and second longitudinal sections (17, 18) in the first and second radial contours (20, 21) in the first and second radial contours (20, 21). The block portion is formed by a projection (25; 31) and a recess (26; 30) formed by three consecutive inclined segments (27, 28, 29; the three consecutive inclined segments (32, 32, 33, 34) define the protrusions and the recesses, the pattern of the three consecutive inclined segments being such that the ends (23, 24) of the coupling portion are offset from each other in a direction transverse to the longitudinal direction of the sipe.

    轮胎(1)包括至少一个块体(8),在所述块体上获得至少一个复杂型刀槽花纹(10),所述复杂型刀槽花纹(10)将块体(8)分成包括彼此面对的第一表面(13)和第二表面(14)的两个部分(11,2)。第一表面(13)在一组第一纵向区段和第二纵向区段(17,18)之间延伸,所述第一纵向区段和第二纵向区段分别具有彼此对称的第一径向轮廓和第二径向轮廓(20,21),所述第一径向轮廓和第二径向轮廓均包括位于两个块体部分(11,12)之间的联接部分,所述块体部分由突起(25;31)和凹部(26;30)形成,由三个接续倾斜段(27,28,29;32,33,34)限定所述突起和所述凹部,所述三个接续倾斜段的花纹使得联接部分的端部(23,24)沿着横向于刀槽花纹的纵向方向的方向相互偏移。
