The invention concerns a tire with a radial carcass reinforcement intended to equip a heavy vehicle such as a transport vehicle or construction machinery. It is a case in particular of a tire which has an axial width greater than 37 inches. The tire according to the invention comprises a working crown reinforcement ( 20 ), consisting of at least two continuous plies ( 15, 16 ) formed from reinforcement elements crossed from one ply to the next, forming with the circumferential direction angles of between 10° and 35°, which is supplemented on each side of the circumferential mid-plane by at least three half-plies ( 17, 18, 19 ) whose reinforcement elements form with the circumferential direction angles of between 10° and 40°, the half-ply ( 18 ) extending axially the most towards the outside being in contact with at least two other working crown half-plies ( 17, 19 ) and the three half-plies ( 17, 18, 19 ) radially overlap the axially external ends of at least two continuous working crown plies ( 15, 16 ).
