Abstract: Tire tread, comprising at least one groove of width W and depth P which is delimited by two walls facing one another, these walls being joined together by a groove bottom, at least one groove comprising at least one flexible device for at least partially closing this groove as it enters the contact patch in which the tire is in contact with a roadway, each flexible device comprising at least one blade of a thickness suited to allowing it to flex under the effect of a circulation of liquid, this at least one blade being borne by a wall delimiting the groove, each blade of thickness E being bounded by a bottom wall facing the bottom of the groove, an end wall facing the other wall of the groove and a contact wall intended to come into contact with the roadway and lateral walls spaced apart from one another by a distance equal to the thickness E of the blade, this tread being such that the bottom wall of the blade comprises a first part extending between the points of connection with the wall bearing the blade,

Abstract: Presented is a tire that includes a crown, which is extended by two sidewalls and two beads and which includes a carcass ply anchored in the beads. The crown includes at least one reinforcing crown ply that includes parallel cables, which are oriented relative to the circumferential direction by an angle ? of between 10 and 45 degrees. The crown further includes at least one hooping crown ply that includes cables oriented in the circumferential direction, which are wound in a spiral. The hooping crown ply is made of a composite fabric that includes a rubber composition based on at least one diene elastomer which is reinforced by hybrid cables that each have a ratio of final tensile tangent modulus:initial tensile tangent modulus which is greater than 10.

Abstract: The present invention relates to hybrid cables, a process for obtaining such and a composite fabric usable in a tire incorporating said cables. The invention also relates to a tire and a mounted assembly which each incorporate such a composite fabric.
