Abstract
The present invention provides rubber compositions that can achieve both abrasion resistance and low heat build-up properties, and pneumatic tires including such rubber compositions. The present invention relates to a rubber composition containing one or more carbon blacks, at least one of which is produced from a feedstock oil that has a BMCI value of not greater than 150 and an aliphatic hydrocarbon content of not less than 30% by mass.
