Claim:
A tire for vehicles of heavy-vehicle type, having a radial carcass reinforcement comprising a crown reinforcement formed of at least two working crown plies of reinforcement elements, crossed from one ply to the other forming angles of between 10° and 45° with the circumferential direction, which itself is topped radially by a tread, said tread being joined to two beads by means of two sidewalls, the crown reinforcement comprising between two working crown plies at least one additional ply of reinforcement elements, wherein axial widths of the at least two working crown plies radially adjacent to the at least one additional ply are greater than an axial width of the at least one additional ply, wherein the axial termination ends of the reinforcement element working ply radially closest to the carcass reinforcement are turned up to cover the axial termination ends of a working crown ply radially external to the at least one additional ply, and wherein the reinforcement elements of the at least one additional ply are formed of metallic circumferentially oriented reinforcement elements over at least part of the axial width of the at least one additional ply.
