During the course of the method of detecting wear on a tyre comprising pattern elements capable of generating first and second acoustic footprint noises (BEAI, BEA2), one of the first or second acoustic footprint noises (BEAI, BEA2) being characteristic of the wear of the tyre, there are selected, from the frequency spectrum of an acquired acoustic signal, a parent frequency spectrum capable of forming the frequency spectrum of one of the first or second acoustic footprint noises (BEAI, BEA2) and a child frequency spectrum capable of forming the frequency spectrum of the other of the first or second acoustic footprint noises (BEAI, BEA2). Two confidence indexes called detection confidence indexes are determined. If each detection confidence index satisfies a predetermined condition, a tyre wear detection warning is issued. |
