Abstract

L’invention concerne un pneumatique comprenant une armature de carcasse constituée d'au moins une couche formée d'éléments de renforcement insérés entre deux couches de calandrage de mélange caoutchouteux. Conformément à l’invention, les couches de calandrage sont constituées d’un mélange élastomérique, comprenant comme charge renforçante majoritairement au moins un noir de carbone, présentant une surface spécifique BET au plus égale à 30 m²/g et un indice COAN au moins égal à 60 ml/100 g et la densité de réticulation mesurée selon la méthode de gonflement à l’équilibre étant comprise entre 13.10-5 mol/cm3 et 21.10-5 mol/cm3 dans les couches de calandrage.
