  The invention is a process for producing a rubber composition containing at least one rubber component (A) selected from natural rubbers and synthetic diene rubbers, a filler containing an inorganic filler (B), a silane coupling agent (C) and a vulcanization accelerator (D), wherein the rubber composition is kneaded in multiple stages, the rubber component (A), all or a portion of the inorganic filler (B), all or a portion of the silane coupling agent (C) and the vulcanization accelerator (D) are added and kneaded in the first stage of kneading, and the specific energy for kneading in the first stage is from 0.05 to 1.50 kWh/kg. The specific energy is obtained by dividing the power consumption by the motor in the kneading device in the first stage of kneading by the total mass of the rubber composition therein. In the process, the coupling function activity can be further increased and a rubber composition favorably having a low-heat-generation property and having good abrasion resistance can be obtained.
