Abstract

"pneumático e utilização de um pneumático" a invenção refere-se a um pneumático comportando um armadura de topo formado de pelo menos duas bi-camadas (5,7) de elementos de reforço paralelos em uma camada, divididos com um passo constante, e cruzados de uma camada à outra que não apresentam uma extremidade livre sobre as suas bordas. de acordo com a invenção, em um plano radial, a densidade de superfície de elementos de reforço em uma zona delimitada pelos centros geométricos de quatro elementos de reforço (12a,12b,13a,13b) adjacentes dois a dois, pertencendo em par a uma bi-camada (5,7), e formando um quadrilátero (11), é superior ao centro do pneumático em relação às extremidades da bi-camada.
