PROBLEM TO BE SOLVED: To provide a tire rim structure, provided with a spare rim device that enables travel to a repairing site even in a case of air leak or explosion when a tire is pierced. SOLUTION: A rim is bound by a ring frame, where the ring frame comprises two semi-circular frames inserted and engaged with each other to be quick-locked by lock members. Binding surfaces of inner arcs are formed to tightly follow irregular variation of various kinds of rims. To outer arcs, circular cushion members are tightly engaged with circular cushion grooves. The circular cushion member is coupled with the spare rim device to form a safety tire that can be quickly combined. In this structure, even when the tire is broken by a pointed item or a blade to make air leak, it can travel safely to the repair site. Hard labor of pushing a car is eliminated. Gravity added when travel is assisted by the spare rim device is reduced by the circular cushion member. Vibration when travel is assisted is reduced, and assisting of travel is smoothed to reduce bounding of a vehicle. COPYRIGHT: (C)2006,JPO&NCIPI
