The invention relates to an inflation-free safety tire which sequentially comprises a tread, an outer ring, a support body and an inner ring from outside to inside, wherein the inner ring is in contact with a rim, the support body is of an annular structure, at least three first damping holes which are uniformly distributed along the circumferential direction of the inner ring are formed in the inner circumference of the support body, second sampling holes corresponding to the first damping holes are formed in the outer circumference of the support body, the first damping holes and the second damping holes are opposite in an arch direction, and the sum of areas of the first damping holes is less than that of the areas of the second damping holes. According to the inflation-free safety tire, by virtue of the support body which are formed by combining and arranging a plurality of and multiple layers of damping holes along a radial direction and a circumferential direction, the vibration and the shock from the ground when the tire runs can be buffered, and the load of a vehicle is borne, the tire is prevented from causing flexion deformity caused by excessive compression, the bearing capability and the service life of the tire are improved, so that the inflation-free safety tire is suitable for tires on various vehicles; by regulating the size of the damping holes or the number of layers of the damping holes, the inflation-free safety tire can realize that the bearing capability of the tire meets the requirement of multiple vehicles from a light load to a heavy load.
