    • The invention provides rubber compositions for tire inner layers, capable of providing excellent ozone resistance over a wide environmental temperature range and of preventing discoloration well, as well as pneumatic tires including such compositions. The invention relates to a rubber composition for tire inner layers, containing C20-C32 normal alkanes. Preferably, the combined amount of the C20-C32 normal alkanes is 0.1-2.5 parts by mass, and the combined amount of phenylenediamine and quinone antioxidants is 0-4 parts by mass, each per 100 parts by mass of the diene rubber component. The rubber composition for tire inner layers preferably contains C48 and higher normal alkanes in a combined amount of not more than 0.1 parts by mass per 100 parts by mass of the diene rubber component. The rubber composition preferably contains not more than 15 parts by mass of process oil per 100 parts by mass of the diene rubber component.
    • 本发明提供轮胎内层用橡胶组合物,能够在宽的环境温度范围内提供优异的耐臭氧性,防止变色,以及包含这种组合物的充气轮胎。 本发明涉及一种含有C20-C32正构烷烃的轮胎内层用橡胶组合物。 优选的是,C20〜C32正构烷烃的合计量为0.1〜2.5质量份,苯二胺和醌类抗氧化剂的合计量相对于二烯系橡胶成分为100质量份为0〜4质量份。 轮胎内层用橡胶组合物优选含有相对于100质量份二烯系橡胶成分为0.1质量份以下的C48以上的正构烷烃。 相对于100质量份的二烯橡胶成分,橡胶组合物优选含有15质量份以下的加工油。
