A tire tread including a tread pattern formed by a plurality of motifs in relief defined by grooves oriented in the transverse direction and in the longitudinal direction of the tread, each of these motifs including a contact face and lateral faces, a plurality of these motifs in relief being connected two by two by at least two rubber connecting elements molded during the molding of the tread. These connecting elements define, with the opposing walls of the motifs in relief to which they are connected, a cavity which closes in contact with the roadway to trap and compress a volume of air once the wear of the tread reaches an appropriate level of wear. For each cavity thus formed at least one rubber element defining the cavity includes at least one orifice which passes completely through said rubber element to cause the volume of the cavity to communicate with a groove.
