Abstract

PNEUMÁTICO COMPORTANDO UMA ESTRUTURA DE REFORÇO DE TIPO CARCAÇA E UTILIZAÇÃO DE UM PNEUMÁTICO. A invenção refere-se a um pneumático comportando uma estrutura de reforço de tipo carcaça (2) e comportando sob a banda de rodagem uma estrutura de reforço de topo (6) constituída de pelo menos duas camadas de elementos de reforço. De acordo com a invenção, a estrutura de reforço de tipo carcaça (2) é realizada em duas semi-camadas (2a, 2b) se estendendo pelo menos dos ombros aos talões e apresentando cada uma extremidade sob a banda de rodagem, pelo menos a superfície da banda de rodagem sendo constituída de uma primeira mistura polimérica (51) se estendendo pelo menos entre as extremidades de cada uma das semi-camadas e pelo menos uma segunda mistura polimérica (52) apresentando propriedades físico-química diferentes das da referida primeira mistura polimérica e cobrindo pelo menos uma parte cada uma das semi-camadas.
