Abstract
There is disclosed a rubber composition particularly suited for use in tires. The rubber composition is composed of 100 parts by weight of at least one rubber containing olefinic unsaturation; and from 1 to 150 parts per 100 parts by weight of rubber, of a silica having predispersed on the surface of the silica a liquid epoxidized butadiene polymer having a number average molecular weight of from 500 to 10,000.
