Provided is a rubber composition that can improve fuel efficiency of a tire in low-temperature environments while ensuring adequate wet performance of the tire. The rubber composition contains: a rubber component (A) including at least 50 mass % of at least one isoprene-based rubber selected from the group consisting of natural rubber and synthetic isoprene rubber; a thermoplastic resin (B); and a filler (C) including at least 70 mass % of silica. The thermoplastic resin (B) is contained in an amount of from 5 parts by mass to 40 parts by mass relative to 100 parts by mass of the rubber component (A). The rubber composition has a tan δ at 0° C. of no greater than 0.5, a difference between tan δ at 30° C. and tan δ at 60° C. of no greater than 0.070, and a storage modulus at 1% dynamic strain and 0° C. of no greater than 20 MPa.
