Abstract
A radial tire includes a crown reinforcement or belt having a lightened belt structure. The lightened belt structure is constructed of a multilayer composite laminate that includes a first layer of rubber that radially surmounts, in a direction Z, two other layers of rubber. The first layer of rubber is reinforced with first reinforcers, which are circumferential heat-shrinkable polyester textile reinforcers. The two other layers of rubber are reinforced with second and third reinforcers, which are monofilaments of high tensile steel. The first reinforcers have a diameter between 0.40 mm and 0.70 mm and a density between 70 and 130 threads/dm, and the second and third reinforcers have a diameter between 0.20 mm and 0.50 mm and a density between 120 and 180 threads/dm.
