A tire carcass is formed of a pair of plies adjacent to each other and extending through the tire from one bead to the other. Each ply comprises cords arranged with the same pitch and along the same direction, and the cords of each ply are staggered with respect to those of the other by half the pitch. The cords of the two plies, in regions of the carcass close to the beads, are located respectively at different distances from the inner wall of the tire. Successive cords of each ply, in regions of the carcass between the midheights of the two sidewalls, are inserted between adjacent cords of the other ply, so that the cords of the two plies, in regions of the carcass between the midheights of the two sidewalls, are located substantially at the same distance from the inner wall of the tire. |
