A method for producing a rubber composition, the method comprising a step of producing a pre-kneaded rubber composition by kneading a butadiene-based rubber and 1 to 20 parts by weight of a silane coupling agent per 100 parts by weight of the butadiene-based rubber and a step of kneading the pre-kneaded rubber composition and 30 to 200 parts by weight of a silica per 100 parts by weight of the butadiene-based rubber used for producing the pre-kneaded rubber composition. |
