The utility model discloses a new type of closed wheel ring. The wheel ring has an inner cavity, which is provided with an air mouth hole through which EPS particles are filled into the inner cavity. The weight of the EPS particles is 90-100g. The EPS particles are heated and expanded by a heating device to foam and fill the inner cavity. The utility model has the following advantages: the closed wheel ring of the utility model fills EPS particles into the inner cavity of the wheel ring through the air nozzle hole, and the EPS material has the characteristics of low density and foaming expansion when heated. The wheel ring is heated by a heating device, so that the EPS particles are heated and expanded and foamed to fill the whole inner cavity, which not only enhances the quality of the wheel ring within the controllable range, but also enhances the quality of the wheel ring due to the fact that The inner cavity is filled with EPS material. When riding at high speed, the airflow gyration is effectively suppressed and the ring sound is eliminated.
