The present invention provides a rubber composition for tires which can maintain good extrusion processability and obtain a good balance of steering stability, fuel efficiency, elongation at break and steering response, and a pneumatic tire using the same. . SOLUTION To 100 parts by mass of a rubber component, 0.5 to 20 parts by mass of an alkylphenol resin and 0.04 to 10 parts by mass of a methylene donor are included, and the alkylphenol resin comprises 2-alkylphenol, 3-alkylphenol, A resin obtained from at least two compounds selected from the group consisting of 4-alkylphenol and formaldehyde, and the total content of free 2-alkylphenol, 3-alkylphenol, and 4-alkylphenol contained in the alkylphenol resin The present invention relates to a tire rubber composition having an amount of 3% by mass or less.
