Abstract
A method for checking and/or monitoring the use of a tire () mounted on a vehicle (), comprises the following steps: acquisition, by a microphone () arranged inside the tire, of an acoustic response of said tire () obtained under the effect of a pulsed mechanical stress thereon, and processing of said response in the frequency domain, characterized in that said processing identifies, in the response in the frequency domain, two spectrum spikes situated on either side of a reference frequency corresponding to the first cavity mode of the tire and, as a function of the frequency deviation between the two duly identified spikes, determines information relating to at least one parameter of use of the tire.
