A radial pneumatic tire comprises one or more carcass plies the cords of which are folded back around steel bead wires and terminate at some distance from the bead wires. At least in the case of the ply the ends of which are farthest from the bead wires, the cords in each folded-back portion are curved so that their length is substantially greater than the minimum distance between the ends of the cords and the closest bead wire. This extends the life of the tire by preventing separation of the cords from the tire elastomer. |
