PURPOSE: A wheel is provided to have excellent durability, drivability, thermal resistance, and impact resistance corresponding to mold, to have extremely excellent separation resistance, and to have improved physical properties in comparison with existing plastic molded products. CONSTITUTION: A wheel is manufactured by a manufacturing method of composite molded products. The manufacturing method of composite molded products comprises: a step of manufacturing a molded product; a step of curing the molded product after coating the molded product with rubber composition. The molded product comprises 30-70 wt% of polybutylene terephthalate, 30-70 wt% of an acrylonitrile-butadiene-styrene mixture, and comprises 1-30 parts by weight of glass fiber or carbon fiber based on 100.0 parts by weight of the mixture. The rubber composition comprises a reactive polyurethane composition, a nitrile butadiene rubber, styrene butadiene rubber, and one or more selected from thermosetting rubber or silicon rubber.
