A rubber composition for pneumatic tires containing a rubber component containing a diene-based rubber and a modified 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 rubber component. 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 rubber component. It is preferred that the modified diene-based rubber is contained in an amount of 1 to 100 parts by mass per 100 parts by mass of an entire amount of the rubber component. It is preferred that the modified diene-based rubber is a diene-based rubber having a polar group.
