A method for monitoring the operational condition of a tire equipping a vehicle, includes: producing, over time, representative samples of successive values assumed by a changing physical quantity, under otherwise equal conditions, with respect to the number of moles of gaseous fluid present in this tire, exploiting these samples in order to deduce from them an estimated condition of the tire, comparing it to a range of normal driving conditions, and producing an alarm in the case where the estimated condition of the tire is situated outside the range of these normal conditions. The step of exploiting the sample includes comparing the value of an indicator of dispersion of the physical quantity, such as the variance of this quantity, to a predetermined threshold value (L).
