Title (EN) TYRE COMPRISING A PROTECTIVE LAYER HAVING IMPROVED ENDURANCE PROPERTIES
(FR) PNEUMATIQUE PRESENTANT UNE COUCHE DE PROTECTION AVEC DES PROPRIETES D'ENDURANCE AMELIOREES
Abstract:
(EN) The invention relates to a tyre comprising a crown reinforcement formed by at least two working crown layers of reinforcing elements and at least one protective layer. According to the invention, the tensile modulus of elasticity at 10% elongation of at least the radially outermost skim coat of at least one protective layer is less than 8.5 MPa, and said at least one skim coat is an elastomer blend comprising a reinforcing filler consisting of a silica- and/or alumina-type white filler.
(FR) L'invention concerne un pneumatique comprenant une armature de sommet formée d'au moins deux couches de sommet de travail d'éléments de renforcement et d'au moins une couche de protection. Conformément à l'invention,le module d'élasticité sous tension à 10%d'allongement d'au moins la couche de calandrage radialement la plus extérieure d'au moins une couche de protection est inférieur à 8,5 MPa, et ladite couche de calandrage étant un mélange élastomérique comportant une charge renforçante constituée par une charge blanche de type silice et/ou alumine.
