How to Replace an Auto Tubeless Tire
In the past, "run-flat" tires, so named because the tires continue to be functional after a puncture, were only used on limousines carrying dignitaries as a security measure. Recently, however, many manufacturers have begun fitting run-flat tires to high-end models as a safety feature. On these tires, the sidewall is reinforced so that the tire can be driven on for short distance, allowing the driver to reach a service station or garage for a repair.
