The invention relates to a tire for heavy vehicle with a radial carcass reinforcement having a width greater than 25 inches comprising at least one working upper reinforcement, comprised of at least one ply of reinforcing elements oriented substantially radially circonferentially, and topped with at least two so-called working plies axially wider than the ply of reinforcing elements oriented substantially circonferentially. According to the invention, each of the working plies is constituted by at least two axially separated parts, the distance between the axially inner end of each of the axially outer parts of at least the radially outermost working ply and the end of the radially outermost ply of the reinforcing elements substantially oriented ciconferentially, being lower than 45 mm and the gap, in the axial direction, between the two parts of each working upper ply being higher than 5 mm. |
