PROBLEM TO BE SOLVED: To provide a reinforcing airbag stored type safety pneumatic tire showing an improved low fuel consumption. SOLUTION: This safety pneumatic tire is constituted by a combination of a tubeless tire 1 and an airbag 2 stored inside the tubeless tire, and a reinforcing layer 11 is arranged at least at a top part of the airbag 2. This safety pneumatic tire is characterized in that the reinforcing layer 11 is constituted by either (1) a rubber-nonwoven-fabric composite layer composed of at least one layer rubber-nonwoven fabrics constituted by a fiber (A) with a tensile elastic modulus of 50GPa or more and a fiber (B) with a dry heat shrinkage coefficient of 1.1% or more at 150°C and rubber or (2) a complex layer composed of at least one layer rubber-nonwoven fabrics constituted by a fiber (A) with a tensile elastic modulus of 50 GPa or more and a rubber, and a rubber-nonwoven-fabric composite layer composed of at least one layer rubber-nonwoven fabrics constituted by a nonwoven fabrics composed of the fiber (B) with a dry heat shrinkage coefficient of 1.1% or more at 150°C and rubber.
