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 polymer mixture layer forming the tire tread is strictly less than 0.270 W/(m.K), said polymer mixture layer forming the tire tread being formed from a rubber composition based on at least one elastomer matrix and at least one reinforcing filler, the elastomer matrix contains predominantly a styrene-butadiene-based copolymer having a glass transition temperature Tg strictly greater than-65 DEG C and less than or equal to-30 DEG C, and the reinforcing filler consists predominantly of an inorganic filler.

    本发明涉及包括胎冠增强件的轮胎,所述胎冠增强件由至少一个周向增强元件层形成。根据本发明,形成轮胎胎面的聚合物混合物层的热导率严格小于0.270W/(m.K),形成轮胎胎面的所述聚合物混合物层由基于至少一种弹性体基质和至少一种增强填料的橡胶组合物形成,所述弹性体基质主要包含玻璃化转变温度Tg严格大于‑65℃且小于或等于‑30℃的苯乙烯‑丁二烯基共聚物,并且所述增强填料主要由无机填料组成。
