ABSTRACT:
The present invention relates to a pneumatic safety tire, which is provided with a ring-shaped projection of high rigidity along its circumferential direction, outside of at least one bead of the pneumatic tire, wherein the projection has a smaller diameter than the diameter of the rim flange to which the tire is fitted. The ring-shaped projection is designed so that it projects to the outside along the rim flange, and moreover, the tire is adhered integrally by vulcanization together with two ring-shaped elastic reinforcements and halogenated butyl rubber-containing protective layer in the inside of the tire at each position corresponding to the portion from the sidewall to the adjacent shoulder. Thus, the purpose of the invention is to provide a pneumatic safety tire, which can be driven safely without there happening such an accident as separation of the bead of the tire from the rim during running, even when the tire is run flat and moreover, has a good stability and durability in running also in such a state.
