To provide a tire capable of automatically detecting abrasion degree.
The tire having a tread 70 and a belt comprising a first and a second plies 50 and 60, the first and the second plies 50 and 60 being made up of metallic reinforcing cords, the cords of the first ply being inclined against the cord of the second ply. The tire, furthermore, comprises at least one resonant circuit formed by a plurality of inductances, electrostatic capacities and at least one bipolar electric elements 101 and 102. The bipolar electric element connects the electrostatic capacities of the resonant circuit to each other and extends into a part of the tread that can be worn away before reaching the tread wear limit, and at least one characteristic of the electrostatic element is modified as a consequence of tire wear before or when the tread wear limit is reached. The resonant circuit is formed by structural elements of the belt of the tire.
