The invention provides a combined vacuum tire. An outer hub with inward rims is additionally arranged outside an original hub, the whole tire is divided into two independent tire sides and a crown attached to the outer wall of the outer hub, and the independent components can be replaced independently. Twenty downward-concave antiskid grooves are formed in the outer wall face of the outer hub at equal intervals. The rims are arranged on the two stepped edges. An original tire rim and the outer tire rim can be sealed by the inner and outer edge rims of the two independent tire sides in the inflation process to form an airtight air cavity. The outer hub with the worn crown is arranged on a grinding machine, pre-vulcanizing crown glue is laid on the ground tire tread, and vulcanization is conducted. By means of the combined vacuum tire, the manufacturing difficulty can be lowered, the tire tread is prevented from being pierced by sharp objects, the heating of a tire body is reduced, and the retreading rate of the tire is increased.
