<p>The invention relates to method for detecting wear to be used for a tire (10) including NEi set(s) of sonic wear indicators corresponding to at least two wear thresholds (S1, S2, S3, S4, S5, S6) so as to generate an acoustic fingerprint noise at least beyond each threshold (S1, S2, S3, S4, S5, S6). Each indicator of each set is substantially axially aligned with each of the other indicators of the set. For each threshold S1, kmin is the minimum value of the values of ki for i ? [2, M], where M is the total number of thresholds with: ki=NEi/NEi-1 when, for the value of i ? 6 [2, M], ? ?i/???i-1 > 1; or ki=NEi-1/NEi when, for the value of i ? [2, M], NEi-1/NEi > 1. For each threshold S1, the acoustic fingerprint noise is detected at a speed V. The value of the speed V is limited to an interval l=[Vmin; Vmax], which complies with Vmax min × Vmin.</p> |
