A rubber composition for pneumatic tires comprising a diene-based rubber, carbon black, and phosphoric acid-modified cellulose nanofiber. It is preferred that the cellulose nanofiber is contained in an amount of 0.1 to 50 parts by mass per 100 parts by mass of an entire amount of the diene-based rubber. It is preferred that the carbon black is contained in an amount of 1 to 80 parts by mass per 100 parts by mass of an entire amount of the diene-based rubber. It is preferred that when a content of the carbon black and a content of the cellulose nanofiber per 100 parts by mass of an entire amount of the diene-based rubber are respectively defined as X and Y, X+Y<80 and 0.05<(Y/(X+Y)<0.5 are satisfied.
