Beschreibung
Zusammenfassung:	A method for producing a rubber composition for a tire, the rubber composition containing a rubber component (A) including at least one selected from the group consisting of natural rubber and diene synthetic rubber, a filler, a coupling agent (D) indicated by chemical formula (1), and a vulcanization agent (E) including a vulcanizing agent and vulcanization accelerator, wherein this method for producing a rubber composition for a tire makes it possible to produce a rubber composition for a tire having an improved balance of fuel economy and wear resistance, the method including: (step X1) a step X1 for kneading the entire amount of A, part of the filler, and part of D; (step X2) a step X2 for kneading the kneading product of step X1 and the remainder of the filler and D; and (step F) a step F for kneading the kneading product of step X2 and E. Chemical formula (1) (CpH2p+1O)3-Si-(CH2)q-S-CO-CkH2k+1 (in chemical formula (1), p represents an integer of 1-3, q represents an integer of 1-5, and k represents an i
