摘要：
A solid industrial polyurethane tire and a wheel assembly comprised of such a tire adhered to a rigid central core, or hub. The hub is generally adaptable to fit onto an axle of an industrial vehicle. Said polyurethane, itself, is prepared by reacting a complex of 4,4'-methylene dianiline and a salt with a prepolymer of selected diisocyanates and selected polyester polyols and polyether polyols and prescribed mixtures thereof.
