Abstract
The method consists in adjusting the pressure of a tire (5) according to a corrected set value Pcc calculated using formula (I), wherein: Pc is a set value recommended by a car manufacturer and a tire producer; Tp is the temperature of the tire (5), supplied by a temperature sensor installed in the tire, and Tref is a variable reference temperature which is selected as being the lowest temperature from the instantaneous ambient temperature measured (at 37) at the site of the inflating machine (2) and a calculated mean value for ambient temperature, the pressures Pc and Pcc being in absolute value and temperatures Tp and Tref being given in degrees K.
