A tire includes a tread, a carcass defining an inner cavity, an inner liner designed to ensure that air contained in the inner cavity remains under pressure, and a radio frequency identification device secured on a free surface of the inner liner. The radio frequency identification device comprises a transmission assembly (1) and a rubber covering structure, the transmission assembly at least comprises an RFID chip (2) and an antenna (3) connected to the RFID chip (2), and the rubber covering structure covers the transmission assembly (1) and is fixed on the free surface of the lining layer. The rubber covering structure has a stress relaxation modulus (Gm (0)) cs that is less than the stress relaxation modulus (Gm (0)) i of the inner liner.
