PROBLEM TO BE SOLVED: To use a vulcanizable rubber, a polyamide elastomer having a melting point of 80 to 180 ° C., and an inorganic reinforcing agent, and for a retread tire having high elasticity, high tensile strength, exothermic property and fatigue resistance. A rubber composition and a retread tire are provided. SOLUTION To 100 parts by weight of vulcanizable rubber (A), 0.1 to 50 parts by weight of a polyamide elastomer (B) having a melting point of 80 to 180 ° C. and 0.1 to 100 inorganic reinforcing agent (C). It relates to a rubber composition for retreaded tires, characterized in that the soft segment of the polyamide elastomer (B) is a polyether and the inorganic compounding agent (C) is carbon black alone or a mixture with silica.
