TYRE FOR HEAVY VEHICLE

摘要

The invention concerns a tyre with radial carcass reinforcement designed to equip a heavy vehicle such as a transport vehicle or a civil engineering machine. It concerns in particular a tyre having an axial length more than 37 inches. The inventive tyre comprises a crown reinforcement (24) consisting of at least two continuous working plies (15, 16, 17, 18) which is completed on each side of a circumferential median plane by at least two half-plies (19, 20) whereof the metal reinforcing elements form with the circumferential direction angles greater than the smallest of the angles of the reinforcing elements of the continuous plies, the half-ply with outermost axial extension being in contact with the axially largest continuous working crown ply and the two-half-plies radially overlapping the axially outer end of said axially largest working ply.
