Abstract

PNEUMÁTICO COMPORTANDO UMA CAMADA DE ELEMENTOS DE REFORÇO CIRCUNFERENCIAIS. A invenção refere-se a um pneumático (1) compreendendo uma armadura de vértice (4) formada de pelo menos duas camadas (41, 43) de vértice de trabalho de elementos de reforço, uma camada C de mistura borrachosa sendo disposta entre pelo menos as extremidades das referidas pelo menos duas camadas de vértice de trabalho (41, 43) e a armadura de vértice (4) comportando pelo menos uma camada (42) de elementos de reforço circunferenciais. De acordo com a invenção, o módulo de elasticidade sob tensão a 10% de alongamento da camada C é superior a 9 MPa e o valor máximo de tan(delta), notado tan(delta)max, da camada C é inferior a 0,100.
