Zusammenfassung:	This disclosure provides a rubber composition for tire obtainable by a method for producing a rubber composition comprising: (a) preparing a preliminary composition by preparing a first mixture containing all of or a part of a diene based rubber (A), a silica (B), a silane coupling agent (C) and an activator (D), and containing a glycerin fatty acid ester (E), and kneading the first mixture; and (b) preparing the rubber composition by adding a vulcanizing agent (t,F) into the preliminary composition to prepare a second mixture, and kneading the second mixture, wherein: the glycerin fatty acid ester (E) is an ester of a glycerin and two or more fatty acids, a fatty acid component which is the most among the two or more fatty acids constituting the glycerin fatty acid ester being 10 to 90 mass % of all the fatty acids.
