Abstract

PNEUMÁTICO COMPORTANDO UMA ESTRUTURA DE REFORÇO DE TIPO CARAÇA E UTILIZAÇÃO DE UM PNEUMÁTICO. A invenção refere-se a um pneumático (1) comportando uma estrutura de reforço de tipo carcaça e comportando sob a banda de rodagem (5) uma estrutura de reforço de topo (6) constituída de pelo menos uma camada de elementos de reforço (10). De acordo com a invenção, pelo menos a superfície da banda de rodagem é constituída de uma primeira mistura polimérica (51) se estendendo pelo menos na zona do plano equatorial e pelo menos uma segunda mistura polimérica (52) apresentando propriedades físico-químicas diferentes daquelas da referida primeira mistura polimérica (51), a estrutura de reforço de topo (6) comportando pelo menos uma camada de elementos de reforço (10) circunferenciais divididos ao longo da direção transversal com um passo variável e o passo entre os elementos de reforço circunferenciais sendo mínimo na zona da camada de elementos de reforço circunferenciais radialmente de frente para as extremidades da primeira mistura (51).
