Abstract

"PNEUMáTICO". A invenção refere-se a um pneumático, cuja relação de aspecto H/S é estritamente superior a 0,55, com armação de carcaça radial (2) compreendendo uma armação de topo (4) formada por ao menos duas camadas (41, 43) de topo de trabalho de elementos de reforço inextensíveis, cruzadas de uma lona a outra fazendo com a direção circunferencial ângulos compreendidos entre 10<198> e 45<198>, ela própria coberta radialmente por uma banda de rodagem (5), a dita banda de rodagem sendo reunida com dois talões pelo intermédio de dois flancos e a armação de topo comportando ao menos uma camada (42) de elementos de reforço circunferenciais. De acordo com a invenção, a relação da espessura do bloco topo com uma extremidade de ressalto (6) sobre a espessura do bloco topo no plano mediano circunferencial (XX<39>) é inferior a 1,20 e a relação da largura axial de ao menos uma camada de elementos de reforço circunferenciais sobre a largura axial da banda de rodagem (L) é superior a 0,5 e de preferência superior 0,6.
