The invention concerns a method for diagnosing the deflation condition of a tyre of a vehicle axle system comprising a first tyre and a second tyre. The main feature of a diagnostic method according to the invention is that it comprises the following steps: - a step of determining the torsional frequency F1 of the first tyre and the torsional frequency F2 of the second tyre; - a step of determining the deviation ΔF between the torsional frequency F1 of the first tyre and the torsional frequency F2 of the second tyre; - a step of evaluating the probability that one of the tyres is under-inflated relative to the other tyre, by calculating the ratio of the absolute value of said deviation ΔF to a threshold value of a relative deviation, representative of under-inflation in one of the tyres.
