    Abstract: A novel carbon black can improve rubber properties (e.g., degree of reinforcement and heat buildup). The carbon black has an aggregate void modal diameter Dmp determined by mercury porosimetry of 25 to 60 nm, and has a ratio (ΔDmp/modal diameter Dmp) of a half-width ΔDmp of an aggregate void diameter distribution determined by mercury porosimetry to the aggregate void modal diameter Dmp of 0.30 to 0.56.

    Abstract: A rubber composition comprises: per 100 parts by weight of a diene-based rubber, from 70 to 95 parts by weight of an inorganic filler containing two types of silicas, a silica X and a silica Y, and a carbon black. A compounded amount of the silica X is x parts by weight and a compounded amount of the silica Y is y parts by weight. A total amount of the silica X and the silica Y (x+y) is 85% by weight or greater of the inorganic filler, and a weight ratio of the silica X to the silica Y (x/y) is from 1/3 to 2/1. A nitrogen adsorption specific surface area of the silica X is 160 m2/g±10%, and a nitrogen adsorption specific surface area of the silica Y is 200 m2/g±10%.
