The present invention provides a rubber composition for a tire that can improve the fuel efficiency, fracture characteristics and extrusion processability in a well-balanced manner while maintaining the hardness, and a pneumatic tire using the same. A rubber component containing a diene polymer modified with a compound represented by the following formula (1), silica, a silane coupling agent, and a liquid resin having a softening point of -20 to 20 ° C. The content of the silica is 10 to 150 parts by mass, the content of the liquid resin is 1 to 25 parts by mass with respect to 100 parts by mass of the rubber component, and the silane cup with respect to 100 parts by mass of the silica The present invention relates to a tire rubber composition having a ring agent content of 1 to 15 parts by mass.
