PURPOSE:To decrease the self-heat-generation property and elevate the blowout temperature limit, by enhancing the productivity with the dehydrated castor oil fatty acid acting as a softening agent during manufacture and without need to use any other softening agent such as, for example, aromatic oil or the like and by, after curing, permitting the fatty acid be crosslinked with sulfur to thereby increase the elastic modulus. CONSTITUTION:In a pneumatic tire comprising a pair of annular elastic reinforcing bodies provided on both side portions of the interior of the pneumatic tire or in the regions of from the side portions to the shoulder portions, the reinforcing body consists of a rubber composition that contains 0.5 to 10 weight part of the dehydrated caster oil fatty acid based on 100 weight part of rubber, to provide a safety tire. |
