Provided is a composition for a foam tire. The composition includes 100 parts by weight of a blend of an olefin block copolymer and a rubber as a polymer matrix, 0.02 to 4 parts by weight of a crosslinking agent, and 1 to 6 parts by weight of a foaming agent. The olefin block copolymer and the rubber are present in amounts of 50 to 80% by weight and 20 to 50% by weight, respectively, based on the total weight of the polymer matrix. |
