1. A method for monitoring pressure in a tire of a wheel of a motor vehicle, the motor vehicle comprising a sensor module generating a signal indicative of a momentary pressure value in the tire, the motor vehicle also comprising a transmission module and a reception module for transmitting information of the momentary pressure value in the tire to a management module, the management module being capable of receiving and processing the information supplied, the management module including a first predetermined pressure value corresponding to a higher vehicle speed value, and the management module including a second predetermined pressure value corresponding to a lower vehicle speed value, the first predetermined pressure value being greater than the second predetermined pressure value, the monitoring method comprising:

  • comparing the momentary pressure value with a target pressure value, the target pressure value corresponding either to the first predetermined pressure value or to the second predetermined pressure value;

    choosing the first predetermined pressure value as target pressure value when the momentary pressure is too low relative to the second predetermined pressure value; and

    choosing the second predetermined pressure value as target pressure value when the momentary pressure is too high relative to the first predetermined pressure value.
