[PROBLEMS] To provide a rubber composition for tie rubber which can realize excellent durability while maintaining good low heat generation property when used in tie rubber of a pneumatic tire subjected to severe use conditions, and pneumatic obtained therefrom. Providing tires. A rubber composition for tie rubber according to the present invention includes at least one carcass ply in which a plurality of steel cords are arranged, an inner liner disposed on the inner side of the innermost carcass ply, and the carcass ply. Modified in which a butadiene polymer used for forming the tie rubber and produced under specific conditions is modified in a pneumatic tire comprising a tie rubber disposed between the inner liner and the inner liner It is a rubber composition for tie rubber obtained by blending carbon black with a rubber component containing a butadiene-based polymer.
