<p>The invention relates to a method for detecting the wear of a tyre including a tread and having at least two predetermined radial wear thresholds Si, during which: beyond each threshold Si, the tread is shaped such as to include NEi sets of audible cavities associated with the threshold Si; and for each threshold Si, kmin is the minimum value of the values of ki, with: Ki=NEi/NEi-1 when for the value of i ? [2, M], NEi/NEi-1 >1, or Ki=NEi-1/NEi when for the value of i ? [2, M], NEi-1/NEi >1 for each threshold, a noise footprint emitted by the audible cavity or cavities associated with each threshold is detected at a speed V, and the value of the speed V is limited for detecting the noise footprint at an interval l=]Vmin; Vmax] verifying Vmax = kmin.Vmin.</p> |
