PROBLEM TO BE SOLVED: To provide a composition for a solid tire which is excellent in ozone resistance, and capable of producing a solid tire having a high value of 100% modulus. SOLUTION: The solid tire composition comprises (C) a copolymer obtained by polymerizing (B) monomer ingredients containing at least one selected from the group consisting of (b-1) an unsaturated nitrile monomer, (b-2) a (meth)acrylic acid-based monomer and (b-3) an aromatic vinyl monomer, in the presence of at least (A) an unsaturated nitrile-conjugated diene based copolymer obtained by polymerizing (a-1) an unsaturated nitrile monomer and (a-2) a conjugated diene monomer, wherein theαvalue of the (C) copolymer, represented by the following formula (1) is≤1.0.α=[tanδ(150°C)-tanδ(60°C)]/tanδ(60°C) (1).
