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.
