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 m/g±10%, and a nitrogen adsorption specific surface area of the silica Y is 200 m/g±10%.
