Summary:Methods for manufacturing a composite rubber tire with a polyurethane tread comprise: treating an outer surface of an internal rubber body; preparing a polyurethane pre-polymer; improving the polyurethane pre-polymer; and applying the polyurethane pre-polymer to the treated outer surface of the internal rubber body to mold a polyurethane tread. Thereby, the composite rubber tire with the polyurethane tread is achieved and has excellent characteristics such as low rolling resistance, low oil consumption, excellent durability and low environmental contamination. Additionally, the methods constitute simple manufacturing processes that reduce manufacturing costs of the composite rubber tire with the polyurethane tread.
