Abstract:
1. A tire comprising a crown reinforcing belt, formed of a plurality of reinforcing plies superposed on one another, each reinforcing ply resulting from the circumferential winding of one or more ply portions comprising threads, parallel to one another, coated with a weakly electrically conducting rubber compound, and making a given angle with the said circumferential direction, in which tire the faces of the circumferential ends of the said portions are butted together to form a butt joint, wherein an electrically conducting continuous linear element runs circumferentially over the radially upper part of each of the plies and crosses from the radially upper part of a first reinforcing ply into the radially upper part of a second reinforcing ply superposed directly on it, passing between the two faces of a butt joint of said second reinforcing ply, and wherein said continuous element comprises an internal leader running over all or part of the radially lower face of the radially internal reinforcing ply of said belt and an external leader running over all or part of the circumference of the radially upper face of the radially external reinforcing ply of said belt.
