A tire tread includes at lest one longitudinal rib limited by grooves. Each rib includes a plurality of incisions each opening into the grooves. Each incision has at least three parts at least two at least of these parts being of essentially transverse orientation and opening into the grooves. At least one other part is oriented essentially in the longitudinal direction. All parts of the incision of essentially longitudinal orientation are devoid any structure for blocking relative movement between the opposing faces of the incision. The parts of essentially transverse orientation include structure for limiting the amplitude of the relative movements of these faces at least in the direction of the thickness of the tread.
