Provided is a production method for a rubber composition for tires which improves the dispersibility of silica and by which a rubber composition for tires that has low fuel consumption performance, wet grip performance, wear resistance, and processability that are improved in a balanced manner is obtained. The production method for the rubber composition for tires includes: a base kneading step of kneading a rubber component containing a butadiene rubber having a cis content of not less than 96% by mass and a Mooney viscosity ML 1+4 (100°C) of not less than 50, silica, a silane coupling agent, and a basic substance; and a finish kneading step of feeding a vulcanizing material to a kneaded product obtained in the base kneading step, and kneading the resultant mixture.
