Provided is a rubber composition for tires in which the temperature dependence of hardness in the rubber composition for tires is reduced and the frictional force on ice is improved. SOLUTION: 100 parts by weight of a diene rubber having a glass transition temperature of −50 ° C. or less, (A) 3 to 30 parts by weight of a tall oil fatty acid ester, (B) a thermally expandable microcapsule, and a thermally expandable A rubber composition for a tire comprising 1 to 15 parts by weight of at least one selected from graphite and a foaming agent-containing resin. [Selection figure] None |
