A rubber composition manufacturing method comprising an operation in which an intermeshing internal kneader is used to knead at least rubber, silica, and silane coupling agent, wherein the operation comprises a first step in which kneading which is accompanied by increase in kneading temperature is carried out during an initial phase of the operation; kneading is carried out during the first step while a ram is maintained in a state in which it is at a first position which is higher than a lowermost position within a range of movement of which the ram is capable; and during the first step, an effective volume when the ram is at the first position is 105% to 120% relative to a value of 100% for an effective volume when the ram is at the lowermost position.
