ABSTRACT:
A tire including a tread and a belt having a first and a second ply. The first and second plies are made up of substantially parallel metallic reinforcing cords embedded in a rubber composition that are inclined with respect to the equatorial plane of the tire, and the cords of the first ply are inclined with respect to the cords of the second ply. At least one dipolar electric element connects at least one cord of the first ply to at least one cord of the second ply. The path followed by the dipolar electric element between the cord of the first ply and the cord of the second ply extends into a part of the tread so as to be worn away before or upon reaching a tread wear limit.
