The invention relates to a polyurethane solid tire material. The polyurethane solid tire material comprises a component A and a component B, wherein the component A is a mixture prepared by mixing polyester polyol, a chain extender, a foaming agent, a catalyst A and a foam stabilizer according to a mass ratio of 100:(5 to 30):(0.3 to 3.0):(0.3 to 3.0):(0.3 to 2.5), the component B is prepared by prepolymerizing isocyanate, polyester polyol and polyether polyol under the existence of a side reaction inhibitor according to a mass ratio of 100:(20 to 50):(0 to 30), and the polyester polyol in the component A and the component B is prepared by prepolymerizing binary acid and polyhydric alcohols under the action of a catalyst B. The component A and the component B are fully mixed, and are then injected into a mold for reaction to form, and demolding and aging are performed, so as to prepare a tire product. The prepared tire product has the advantages of low density, stable size, high tread hardness, good abrasion resistance and good bonding capability with other accessories of the tire.
