Run-flat tires, as the name suggests, are designed to allow you to drive up to 80 km (50 miles), depending on the type of tire, at a limited speed of 80 to 90 km/h (50 mph) in the event of a puncture or loss of pressure.

The vehicle fitted with run-flat tires must have working wheel air pressure sensors so that you'll see a tire pressure warning light if the pressure loss happens. Without these sensors, you won’t have a chance to know that there is a problem.
