Disclosed herein is a low fuel consumption pneumatic tire with all weather running performances, which tire uses as a tread a vulcanizable rubber composition obtained by adding 30-80% by weight of carbon black having an iodine adsorption value of not less than 70 mg/g and a dibutylphthalate (DBP) absorption of not less than 90 ml/100 g, and a low temperature plasticizing ester and/or naphthenic or paraffinic softener in an amount 2 to 50% by weight relative to said carbon black into 100 parts by weight of a rubber component composed of 100 to 25 parts by weight of at least one kind of a first diene rubber containing 0 to 30% of styrene and 25 to 95% of vinyl bonds in the butadiene unit and 0 to 75 parts by weight of at least one kind of a second diene rubber which is different in kind from the above first diene rubber.

硫化橡胶组合物作为胎面,该组合物是通过在由 100 至 25 重量份组成的橡胶组分中加入 30 至 80 重量份的
炭黑(其
碘吸附值不小于 70 毫克/克,
邻苯二甲酸二丁酯(
DBP)吸收量不小于 90 毫升/100 克)以及低温塑化酯和/或环烷或石蜡软化剂(相对于所述
炭黑的重量为 2 至 50%)而获得的、和低温塑化酯和/或环烷或石蜡软化剂,相对于所述
炭黑的重量比为 2 至 50%,加入 100 份(重量比)橡胶组分中,该组分由 100 至 25 份(重量比)至少一种第一二烯橡胶(
丁二烯单元中含有 0 至 30%
苯乙烯和 25 至 95%
乙烯键)和 0 至 75 份(重量比)至少一种第二二烯橡胶(与上述第一二烯橡胶的种类不同)组成。
