The wear detection method applies to a tyre (10) comprising NEi set(s) of acoustic wear indicators associated with at least two wear thresholds (S1, S2, S3, S4, S5, S6) so as to generate an acoustic fingerprint noise, at least when each threshold (S1, S2, S3, S4, S5, S6) has been exceeded. Each indicator of each set is substantially axially aligned with each other indicator of the set. For each threshold Si, kmin is the minimum value of the values of ki for iε[2, M] where M is the total number of wear thresholds, with: ki=NEi/NEi-1 when for the value of iε[2, M], NEi/NEi-1>1, or ki=NEi-1/NEi when for the value of iε[2, M], NEi-1/NEi>1 For each threshold Si, the acoustic fingerprint noise is detected at a speed V. The value of the speed V is limited to an interval I=[Vmin; Vmax] satisfying Vmax≰kmin·Vmin.
