To provide a rubber composition for tires which serves as a raw material of a vulcanized rubber for tires improved in WET performance, rolling resistance and wear resistance in a well-balanced manner, and to provide a pneumatic tire comprising a vulcanized rubber of the rubber composition.SOLUTION: The rubber composition for tires contains a rubber component, carbon black, and a vegetable oil. The nitrogen adsorption specific surface area of the carbon black is 120-250 (m2/g). The nitrogen adsorption specific surface area of the carbon black is preferably 160-250 (m2/g).SELECTED DRAWING: None
