(EN) TYRE HAVING IMPROVED PROPERTIES OF ENDURANCE AND ROLLING RESISTANCE
(FR) PNEUMATIQUE PRESENTANT DES PROPRIETES D'ENDURANCE ET DE RESISTANCE AU ROULEMENT AMELIOREES
Abstract
(EN) The invention relates to a tyre comprising a crown reinforcement formed from at least one layer of circumferential reinforcing elements. According to the invention, the thermal conductivity of the layer of polymer mixture forming the tyre tread is strictly less than 0.270 W/(m.K)) and said layer of polymer mixture forming the tyre tread is formed from a rubber composition based on at least one elastomer matrix mainly comprising a styrene-butadiene-based copolymer having a glass transition temperature Tg strictly higher than -65°C and lower than or equal to -30°C, and at least one reinforcing filler mainly consisting of an inorganic filler.
(FR) L'invention concerne un pneumatique comprenant une armature de sommet formée d'au moins une couche d'éléments de renforcement circonférentiels. Conformément à l'invention, la conductivité thermique de la couche de mélange polymérique formant la surface de roulement est strictement inférieure à 0.270 W/(m.K) et ladite couche de mélange polymérique formant la surface de roulement est formée d'une composition de caoutchouc à base d'au moins une matrice élastomère comprenant à titre majoritaire un copolymère à base de styrène et de butadiène ayant une température de transition vitreuse Tg strictement supérieure à -65°C et inférieure ou égale à -30°C et d'au moins une charge renforçante comprenant à titre majoritaire une charge inorganique renforçante.
