ABSTRACT:
The invention relates to an emergency running ring for pneumatic tires mounted on vehicle rims. A lubricant is contained in cavities formed by virtue of the shape of the ring, or is contained in auxiliary members mounted in openings in the ring or mounted on the surface of the ring. In all instances, the loss of tire pressure due to emergency conditions causes the lubricant to be released so as to reduce the friction between the inner face of the tire cover and the ring.
