摘要： A tire comprising a tread, a carcass defining an inner cavity, an innerliner layer designed to make sure that the air contained in the inner cavity remains under pressure, and a radio-frequency identification device, which is fixed on a free surface of said innerliner layer. The radio-frequency identification device comprises a transmission assembly comprising at least a RFID chip and an antenna connected to the RFID chip, and a rubber covering structure, which covers the transmission assembly and is fixed on a free surface of the innerliner layer. The rubber covering structure has a stress relaxation modulus (Gm(0))cs smaller than the stress relaxation modulus (Gm(0))i of the innerliner layer.

摘要： The invention relates to a method and a system for the processing of an end-of-use pneumatic tyre that is provided with an inner lining (SAL) layer manufactured with a sealing agent intended to seal any punctures and at least partially applied to the surface of an inner cavity (2) of the end-of-use pneumatic tyre; the system (1) comprises an applicator device (6), which is provided with at least one nozzle (13) which dispenses a cryogenic fluid, preferably liquid nitrogen, upon the (SAL) layer of sealing agent in such a way that the (SAL) layer of sealing agent reaches the solid state; a device (14) for the removal of the (SAL) layer of solid sealing agent that is provided with a tool (16) for removing the (SAL) layer of solid sealing agent by means of mechanical abrasion; and a circuit (17) for suctioning the solid sealing agent removed by the tool (16).
