Abstract
A tire assembly comprising outer and inner tires having at least one vent and one plug is described. The vents and plugs mate in the assembly providing an air tight seal in the bead seal region of the tires. The vents or plugs permit air to escape from the outer tire if an attempt is made to mount the outer tire on a rim without a mating inner tire.
