Abstract: A heavy goods vehicle tire has a radial carcass reinforcement, made up of a single layer of metal reinforcing elements anchored in each of the beads by a turn-up around a bead wire. The turn-up of the carcass reinforcement layer and the main part of the carcass reinforcement layer are coupled, and a radiofrequency communication module is placed in the coupling region at the interface between the turn-up of the carcass reinforcement layer and axially outwardly adjacent layer of rubber compound.

Abstract: A pneumatic tire has a passive transponder incorporated therein that allows communication with a radio-frequency reader located outside the pneumatic tire. The passive transponder includes at least one radiating antenna and is embedded in an electrically insulating elastomeric blend to form a patch. The patch extends axially between an axially inner end of a carcass ply of the pneumatic tire and an inner surface of the pneumatic tire. The patch also extends radially at a distance between a bead toe of the pneumatic tire and a radially outer end of a bead core of the pneumatic tire.

Abstract: A system is provided for dynamically reading data from transponders of tires disposed laterally on a same side of a vehicle. The system includes antennas, a sensor for each antenna, a reader, a controllable switch, and a programmable logic controller. The antennas are arranged to receive data transmitted by the transponders. Each sensor is positioned upstream of an effective reading area covered by a corresponding one of the antennas, and each sensor transmits a signal associated with passage of a tire. The reader is arranged to couple to the antennas in order to read and store data from the transponders. The switch is positioned between the antennas and the reader to provide a selective coupling between the reader and each of the antennas. The controller controls the switch as a function of wheel-passage sensor signals.
