Abstract
L’invention concerne un pneumatique comprenant une armature de sommet formée d'au moins deux couches de sommet de travail d'éléments de renforcement, une couche C de mélange caoutchouteux étant disposée entre au moins les extrémités desdites au moins deux couches de sommet de travail. Selon l’invention, la valeur maximale de tan(δ), noté tan(δ)max, de la couche C est inférieure à 0.055 et l’allongement à rupture de la couche C est supérieur à 300 %. Figure pour l’abrégé : Fig 1
