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.
