A radial tire with a lightened belt structure () comprises a multilayer composite laminate () of specific construction, with a first layer () of rubber (C) reinforced with preferably weakly heat-shrinkable circumferential textile monofilaments () with a diameter greater than 0.10 mm or assemblies of such monofilaments, for example, made of nylon or of polyester, this first layer radially (in the direction Z) surmounting two other layers () of rubber (C, C, respectively) reinforced with monofilaments () of high tensile steel. The first reinforcers have an envelope diameter between 0.20 mm and 1.20 mm and a density, measured in the axial direction Y, between 70 and 130 threads/dm, and the second and third reinforcers each have a diameter between 0.20 mm and 0.50 mm and a density, measured in the axial direction Y, between 100 and 180 threads/dm.
