Abstract: The present invention relates to an explosion-proof security tire for vehicles. The tire includes an outer tire, a split rim, a L-shaped sealing ring, a combined support loop and a valve core. The combined support loop includes a plurality layers of support rings they are sleeved by layer on layer and fixed with the rim. The size of the tire can increased by the combined support loop so as to furthest shorten the distance between the inner wall of the outer tire and the outer wall of the combined support loop at a normal pressure of tire. At the moment that the tire is burst, the combined support loop can support the outer tire quickly and effectively, and control the change of acting radius of the tire in a minimum range so as to ensure the basic performance of the tire and to prevent accidents caused by sudden control loss of running direction and avoid potential security risks.
