A tire tread of elastomeric material formed into ground engaging elements (1) is provided with sipes (2) in said elements. The sipes are in the form of incisions. A first incision portion(s) extends inwardly from the tread surface and then splits into at least two incision portions (3,4) which continue to extend away from the tread surface while at the same time diverging apart from one another. In one embodiment one of the incision portions splits up into two incision portions diverging apart from each other and extending away from the tread surface.
