    摘要： Tire comprising a tread having a tread surface (11) and comprising a plurality of grooves (2) of generally circumferential orientation and of depth H, these grooves (2) defining a plurality of rubber elements (3, 30), at least one of which comprises a plurality of cavities (6), each cavity (6) of volume Vc of generally elongate shape with a total length Lc and being designed to communicate with a single groove (2) of generally circumferential orientation, each cavity (6) being extended all the way along its length Lc by an incision (80) which extends radially outwardly to emerge at the tread surface (11), this tire being such that the incision (80) comprises an incision portion (81) beginning at the cavity and forming an angle A of at least 10° with a line perpendicular to the tread surface and passing through the point of intersection of the incision with the cavity (6).

    摘要： A tire comprising a tread having a running surface, and at least one groove of generally circumferential orientation and a plurality of relief elements, each of which has a contact face with a transverse width Lt and lateral walls, at least one being provided with a plurality of devices for attenuating resonance noise, being formed in a relief element and comprising a cavity of elongate shape having a total length Lc and a total volume Vc, opening onto a lateral wall, having a total length Lc which is greater than the transverse width Lt, and a geometry comprising several cavity portions connected together, wherein the length Lc equal to the sum of the lengths of all the cavity portions, being extended over the whole of its length Lc by a sipe extending radially outwards opening onto the running surface, this tread being such that the sum Ly of the lengths projected in the transverse direction of each cavity is at least 1.5 times greater than the sum Lx of the lengths projected in the circumferential direction of each cavity.
