The present invention aims to provide pneumatic tires that can achieve both abrasion resistance and low heat build-up properties. The present invention relates to a pneumatic tire including a tread formed from a rubber composition, the rubber composition containing: a rubber component including an isoprene-based rubber and a high-cis polybutadiene rubber having a cis content of 90% by mass or more; one or more types of carbon black; and sulfur, at least one of the one or more types of carbon black being produced from a feedstock oil that has a BMCI value of 150 or less and an aliphatic hydrocarbon content of 30% by mass or more, the BMCI value being calculated from the average boiling point T (° C.) and the specific gravity D (60/60° F.) relative to water at 60° F. according to the equation below,
BMCI=48,640/(T+273)+473.7D−456.8.
本发明旨在提供可同时实现耐磨性和低热积聚特性的充气轮胎。本发明涉及一种充气轮胎,包括由橡胶组合物形成的胎面,橡胶组合物包含橡胶成分,包括
异戊二烯基橡胶和顺式含量为 90% 或以上的高顺式聚
丁二烯橡胶;一种或多种类型的
炭黑;以及
硫磺,其中至少一种或多种类型的
炭黑由
BMCI 值为 150 或以下且脂肪族碳氢化合物含量为 30% 或以上的原料油制成,
BMCI 值由平均沸点 T (°C.)和比重 D (°C.)计算得出。)和相对于 60°F 时
水的比重 D(60/60°F、
BMCI=48,640/(T+273)+473.7D−456.8.
