Abstract
The invention proposes a technique of preventing a propagation of a damage in a reinforcing layer to a toric air bag even if the reinforcing layer arranged on an outer peripheral side of the toric air bag in a safety tire to suppress an unnecessary size growth of the toric air bag and allowed to a proper expansion deformation of the toric air bag in the puncture of the tire or the like is damaged by foreign matters entered through a puncture hole into the tire, in which the reinforcing layer separately arranged from the toric air bag is fitted on the outer peripheral side of the toric air bag having a hollow torus shape over its full periphery to suppress the propagation of the damage in the reinforcing layer to the toric air bag through an interface layer therebetween.
