PROBLEM TO BE SOLVED: To provide a pneumatic safety tire capable of maintaining at a high level the normal running performance (riding comfort etc.) when filled with the internal pressure, compared with a conventional safety tire having a reinforcing rubber layer, and equipped with a largely improved run-flat durability due to possibility of enhancing the tire crosswise spring when the internal pressure is 0 kPa. SOLUTION: The pneumatic safety tire is equipped with a left and a right bead ring 14, a carcass layer 20 in which a plurality of cords are embedded parallel in a covering rubber, and a pair of side wall parts 18 arranged outside in the tire radial direction of the carcass layer 20, wherein rubber including short fibers is arranged in the reinforcing rubber layers 30 of the side wall parts 18, in which the short fibers are oriented in the tire circumferential direction.
