The invention relates to a tire for a heavy vehicle comprising a radial carcass reinforcement over which a working crown reinforcement is placed, the carcass reinforcement comprising at least one ply of reinforcing elements anchored in each of the beads by winding around a bead wire for forming a ply turn-up. According to the invention, the radially outer end of the ply turn-up is situated at a distance from the radially outer part of the bead wire that is less than 40 % of the height of the sidewall. Said tire comprises at least one complementary ply of radially oriented reinforcing elements, having moduli of compression and of extension of at least 1.5 times less than that of the ply of the carcass reinforcement, and this complementary ply is axially adjacent to the ply turn-up of the carcass ply along a distance greater than 15 % of the height of the sidewall. |
