    • The present invention provides a method for producing a rubber composition containing a rubber component (A) which contains a copolymer of a conjugated diene compound and an aromatic vinyl compound, in which the conjugated diene compound amount in the copolymer is 50% by mass or more and 73% by mass or less and the molecular weight at the peak top of the molecular weight distribution of the polystyrene-equivalent number-average molecular weight of the copolymer as measured through gel permeation chromatography is 100,000 or more and 600,000 or less, a filler containing an inorganic filler (B), a silane coupling agent (C) and at least one accelerator (D) selected from guanidines, sulfenamides, thiazoles, thiurams, thioureas, dithiocarbamates and xanthates, wherein the rubber composition is kneaded in plural stages, and in the first stage (X) of kneading, the rubber component (A), all or a part of the inorganic filler (B), all or a part of the silane coupling agent (C) and the accelerator (D) are added and kneaded. The production method can produce a rubber composition excellent in low-heat-generation property and abrasion resistance.
