특히 승용차 또는 라이트 밴(light van)용 래디얼 타이어는 특정 구조의 다층 복합 라미네이트(10a, 10b, 10c)를 포함하는 경량화된 벨트 구조체(10)를 갖고, 예를 들어 PET 또는 PEN과 같은 폴리에스테르로 제조된 열 수축 가능한 원주방향 직물 보강재(110)를 포함하는 고무(C1)의 제1 층(10a)을 갖고, 이 층은 고강도 강의 모노필라먼트(120, 130)로 보강된 고무(각각 C2, C3)의 2개의 다른 층(10b, 10c)에 반경방향으로(방향 Z로) 장착하고, 이 다층 복합 라미네이트는 코너링 강성 및 따라서 노면 접지성에 악영향을 미치지 않는 동시에 향상되지 않으면 적어도 동일한 도로 주행 내구성을 제공하면서 중량 및 구름 저항을 감소시키는 것을 가능하게 한다.

    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.
