The purpose of the present invention is, regarding the rubber composition for a tire containing natural rubber as a main component among rubber components thereof, to maintain the performance both on snow and wet road surfaces by imparting flexibility to the rubber composition, to improve workability by increasing the viscosity of the rubber composition in the unvulcanized state, and to improve the low loss properties of the vulcanized rubber composition. The rubber components include 60 mass% or more of natural rubber, and the rubber composition contains 8-40 parts by mass of a thermoplastic resin with respect to 100 parts by mass of the rubber components, and isophthalic acid dihydrazide. |
