<p>A tyre for a vehicle has at least two predetermined radial wear thresholds. Beyond each threshold, a tread of the tyre is configured in such a way that the tread includes at least one set of at least one cavity, known as a sounding cavity, associated with that threshold. If a set includes a plurality of cavities, each cavity of the set is substantially aligned axially with each other cavity of the set. A number of the set(s) of cavity/cavities associated with each threshold is different from a number of the set(s) of cavity/cavities associated with each other threshold. The sets of sounding cavities are arranged in such a way that, beyond each threshold, the set(s) of sounding cavity/cavities associated with that threshold are evenly circumferentially distributed about the tyre.</p> |
