The invention refers to a manufacturing technology for composite tire. Detailedly speaking it refers to a manufacturing method for polyurethane-rubber composite tire. Adopt the composite structure of polyurethane tread and rubber carcase and modify and optimize low polymer polyol/butylene oxide-propylene epoxide copolyether-p-diisocyanate and polybutadiene glycol-diphenylmethane diisocyanate. Treat an outer surface of an internal rubber body and cast. It owns good property of low temperature and high heating-resisitant. So it can be used in high-speed condition and also it has long lifetime. Besides, its manufacturing method is easy and its cost is low, so it can be easily put into industrialization.
