<p>Tyre comprising a tread (70) and a belt comprising a first (50) and a second (60) ply, the first and second plies being made up of substantially parallel metallic reinforcing cords (51,61) embedded in a rubber composition that are inclined with respect to the equatorial plane of the tyre, the cords (51) of the first ply (50) being inclined with respect to the cords (61) of the second ply (60), the tyre moreover comprising at least one resonant circuit formed by a plurality of inductances (L) and capacities (C) and at least one dipolar electric element (101,102) connecting capacities of the resonant circuit and extending into the part of the tread (70) that can be worn away before reaching the tread wear limit, such that at least one characteristic of the dipolar electric element (101,102) is modified as a consequence of tyre wear before or when the tread wear limit is reached, wherein the resonant circuit is formed by elements of the belt of the tyre.</p> |
