Abstract: To improve the load supporting capability of a pneumatic safety tire and to prevent the tire bead portion from coming off from the rim seat both during run-flat (flat punctured tire) travel, the pneumatic safety tire comprises a pair of crescent-shaped cross-section reinforcing rubber layers each having the thicknest portion at the tire side portion and a pair of beak-shaped cross-section rim-fixed protruding hard-rubber members each disposed under the reinforcing rubber layer in such a way that annular circumferential bonding surfaces between the two are inclided axially outwardly or inwardly in annular wedge shape. Further, to prevent creases from being produced during green tire forming process and cracks from being produced during run-flat travel in or near the bonding surfaces, crescent-shaped reinforcing layer and the beak-shaped rim-fixed protruding members are extrusion-formed simultaneously before a green tire is formed.
