The invention relates to the technical field of polyurethane tires, in particular to a high-wear-resistance polyurethane tire and a preparation method thereof. The invention discloses a high-wear-resistance polyurethane tire, which is prepared from the following raw materials in parts by mass: 50 to 60 parts of polyester polyol, 10 to 20 parts of diisocyanate, 1 to 3 parts of chain extender and 1 to 3 parts of foaming agent. Compared with the prior art, the high-wear-resistance polyurethane tire has the beneficial effects that the polyester polyol reacts with the diisocyanate, the chain extender and the foaming agent are added, the high-wear-resistance polyurethane tire is obtained through vulcanization, the shore hardness of the obtained polyurethane tire reaches up to 102, the Akron wear reaches up to 0.02, the tear strength reaches up to 104, and the service life of the high-wear-resistance polyurethane tire is prolonged. The maximum aging coefficient reaches 0.97, and the cable has excellent performance.
