Abstract
reforço de coroa do pneu constituído por duas camadas da coroa de trabalho e uma camada de elementos de reforço circunferenciais. a invenção refere-se a um pneu do tipo para serviço pesado destinado a ser instalado em um aro com centro rebaixado do tipo de centro rebaixado de 15°. de acordo com a invenção, as duas camadas da coroa de trabalho e a camada de elementos de reforço circunferencial são as únicas presentes para formar o reforço de coroa em pelo menos 40 % da largura da banda de rodagem, em que o valor absoluto da diferença entre os valores absolutos dos ângulos a2 e a1 são maiores que 7°, em que a2 é maior que a1 em termos de valor absoluto, em que o ângulo médio a satisfaz a relação 28+110*exp(-l/100) <a <32+110*exp (- l/100), e os elementos de reforço do reforço da carcaça, no teste denominado teste de permeabilidade, que rende uma taxa de fluxo inferior a 20 cm3/min, havendo um composto de borracha presente no interior dos cordonéis.
