A tire rubber composition contains: 100 parts by mass of a diene rubber containing 55 mass % or more of a solution-polymerized styrene-butadiene rubber whose glass transition temperature is −50° C. or lower; 30 parts by mass or more and less than 100 parts by mass of a white filler; and 15 parts by mass or more of a thermoplastic resin, from 3 to 20 mass % of a silane coupling agent being blended relative to a mass of the white filler. The rubber composition satisfies Tga-Tgm of 10° C. or less, where Tga is a theoretical glass transition temperature of a mixture in which the diene rubber and the thermoplastic resin are blended at a mass ratio of 1:1, Tga being calculated from glass transition temperatures of the diene rubber and the thermoplastic resin, and Tgm is a measured glass transition temperature of the mixture.
