Abstract:
A tire tread having a plurality of ribs delimited by cut-outs, each having a generally parallelepipedal shape and having a length (L) and a width (W), the width (W) being determined between a first lateral face and a second lateral face of the rib, the width (W) being less than the length (L), at least one rib having at least one cavity placed inside the rib, the cavity extending mainly in the length (L) of the rib. The tread having an incision extending mainly in the length (L) of the rib, the incision emerging on the first lateral face of the rib and the incision emerging in the cavity while forming an opening, the length (Lo) of the opening determined in the length (L) of the rib corresponding at least to 80% of the length (Lc) of the cavity determined in the length (L) of the rib.
