1. A method for locating a thermal anomaly on tire-wheel assemblies of a vehicle, each of which is equipped with a mounting wheel on which a pneumatic tire is mounted, the method comprising:
implementing, on a reference set comprising at least one tire-wheel assembly selected from among the tire-wheel assemblies of the vehicle, a method for detecting a thermal anomaly comprising the steps of
measuring an internal pressure P and temperature T of the tire-wheel assembly using a sensor attached to the mounting wheel,
calculating a monitoring ratio P/T which is a function of the measured pressure P and of the measured temperature T and a function of each of the tire-wheel assemblies of the reference set, and
repeating the preceding steps and tracking an evolution in a value of the monitoring ratio P/T in order to determine a thermal anomaly when the internal temperature of the tire-wheel assembly increases more rapidly than the internal pressure of the tire-wheel assembly;
implementing the method for detecting the thermal anomaly on a comparison tire-wheel assembly of the vehicle not belonging to the reference set; and
calculating a difference ΔP/T between the monitoring ratios P/T of the reference set and of the tire-wheel assembly compared during iterations in order to determine whether a thermal anomaly is coming from the reference set or from the compared tire-wheel assembly.
