The invention provides a hollow maintenance-free tire, relates to the technical field of tires, and solves the technical problems that traditional pneumatic tires in the prior art are easy to be punctured and burst and leak slowly, and traditional solid tires are heavy. The hollow maintenance-free tire provided by the invention comprises an inner tube and an outer tube, the outer tube wraps the outside of the inner tube, and the outer circumferential surface of the outer tube forms a landing part in contact with the ground. The inner tube is of a hollow and inflation-free structure and forms a supporting part of the outer tube. The invention reduces the overall weight of the tire, and the inflation-free structure of the inner tube can avoid the phenomena of easy puncture, burst and slow air leakage of the pneumatic tire, thereby reducing the trouble of maintenance.
