1. A method for signaling the theft of a wheel of a motor vehicle, said vehicle comprising a plurality of wheels and a computer, with at least one of the wheels comprising a sensor, said method comprising, for the at least one wheel:
measuring at least one value of an internal pressure of the tire of the wheel;
detecting that the vehicle has been raised when an absolute value of a difference between the at least one measured internal pressure value and a predetermined reference internal pressure value is greater than a predetermined pressure difference threshold;
when raising of the vehicle is detected, detecting a detachment of the wheel;
when the detachment of the wheel is detected, signaling the theft of the wheel;
wherein the detecting the detachment of the wheel comprises:
in a mode called “raising” mode, the sensor periodically transmitting a raising detection signal to the computer as long as the raising of the vehicle is detected;
the computer receiving said transmitted raising detection signal;
measuring a strength of the received raising detection signal; and
the computer detecting the detachment of the wheel if at least one measured strength value is less than a predetermined strength threshold.
