PROBLEM TO BE SOLVED: To provide a rubber composition for a tire, which has excellent wear resistance, can improve a browning phenomenon of a tire skin rubber, and is particularly suitably used for a tread rubber.SOLUTION: The rubber composition is prepared by compounding at least one rubber component selected from diene-based synthetic rubber and natural rubber, carbon black having a nitrogen adsorption specific surface area of 140 m/g or more, and at least one nonionic surfactant selected from compounds expressed by formula (I): RO(RO)H. In formula (I), Rrepresents an alkyl group or an alkenyl group having 1 to 15 carbon atoms, in which the alkyl group and the alkenyl group may be any forms of a chain, a branch or a ring; Rrepresents an alkylene group having 2 to 4 carbon atoms; and n is 11 to 30. |
