Abstract
A heat-dissipating valve is formed on a steel rim of a car tire which includes an inner tire secured in an outer tire, whereby upon puncture of the outer tire, the inner tire, when compressed between the outer tire and the steel rim as loaded by a car weight, may release hot air outwardly through the heat-dissipating valve for dissipating frictional heat outwardly as produced by the friction between the inner tire and the steel rim or outer tire to prevent a fire accident.
