Abstract

Le pneumatique (10) comprend une armature de sommet (16) comprenant une armature de travail (20) comprenant une couche de travail radialement la plus extérieure (26) ainsi qu'une armature de frettage (22) comprenant plusieurs éléments de renfort filaires de frettage textiles (220) enroulés en hélice radialement autour de l'armature de travail (20) et reliés les uns aux autres par un ou plusieurs élément(s) filaire(s) de trame (42). Dans la partie axialement centrale (P0) du sommet (12), la distance radiale moyenne E2 entre les éléments de renfort filaires de frettage textiles (220) et les éléments de renfort filaires de travail métalliques (260) est telle que E2 ? 0,40 mm. Chaque élément filaire de trame (42) comprend plusieurs monofilaments textiles et/ou plusieurs fibres textiles choisi(e)s parmi les monofilaments et les fibres synthétiques polymériques organiques, les monofilaments et les fibres synthétiques polymériques inorganiques et les assemblages de ces monofilaments et fibres.
