Abstract

a invenção se refere a um pneumático com armadura de carcaça radial (2), constituída por uma camada de elementos de reforço ancorada em cada um dos talões por reviramento em torno de um cordonel (4), o dito reviramento de armadura de carcaça sendo reforçado por pelo menos uma camada de elementos de reforço ou enrijecedor (8). de acordo com a invenção, a densidade relativa de pontes de enxofre medida de acordo com o método de inflação no equilíbrio é inferior a 5 % em pelo menos 30 % das misturas elastoméricas presentes na superfície de pelo menos uma zona z em um plano meridiano, as ditas misturas elastoméricas sendo composições à base de pelo menos um elastômero diênico escolhido no grupo dos elastômeros diênicos constituído pelos polibutadienos (em abreviado ?br?), pelos poliisoprenos (ir) de síntese, pela borracha natural (nr), pelos copolímeros de isopreno, pelos copolímeros de butadieno com exceção dos copolímeros butadieno-nitrila (nbr), com exclusão dos elastômeros diênicos que portam funções carboxilas, e pelas misturas desses elastômeros diênicos.
