This method makes it possible to manage data relating to an assembly (10) comprising a tyre (12), carrying an RFID marker (16), and a rim (14), carrying a wheel module (22) comprising at least one sensor (P, T). The assembly (10) may be in various states, in particular a mounted state in which the tyre (12) is mounted on the rim (14) to form a mounted assembly (10), also called a wheel, intended to equip a motor vehicle. According to this method, data is transmitted between the RFID marker (16) and the wheel module (22) via an intermediate unit (28), separated from the mounted assembly (10) and from the motor vehicle, comprising means for transmitting data (42, 50, 52, 54). These data, termed RFID data, are stored in the wheel module (22). The wheel module (22) comprising at least one tyre pressure sensor (P), the RFID data stored in the wheel module (22) are erased when the pressure detected by the pressure sensor (P) is less than or equal to a pretermined pressure threshold.
