Helical spring loop structures (inner tires) reduce vehicle accidents when tire failure occurs, reduce tire heat build-up and tread wear simultaneously. The structure, having an ability to cope with a vehicle's failed tire while in motion, provides a safer driving environment. The structures preferably are made of steel oil tempered wire, ASTM A-229 or equal, covered with rubber tubing and assembled to form a loop which can be inflated. The wire provides structural stability and the rubber tubing provides cushioning, especially when inflated.
