To provide a safety tire enabling to be easily manufactured, simply to install a rim, to hold low fuel consumption, having durability for normal travelling and having sufficient load supporting performance for punctured travelling.

The safety tire with a built-in tube furnished with a belt member and a temporarily fitting member for its connection on an outer peripheral part is assembled on the rim, and the tube has an outer peripheral part shape to hold a clearance between itself and an inner surface of a tread part against centrifugal force by the belt member in a tread part grounding region under a travelling condition of the assembly body to load a load corresponding to the maximum pneumatic pressure of the tire on the assembly body of the safety tire and the rim respectively and separately filling internal pressure in the pneumatic tire and the tube.
