How run-flat tires work

Run-flat tires are engineered to keep you moving after a puncture for a limited distance and speed—typically up to 50 miles at up to 50 mph. Always check the tire manufacturer’s specific guidance for your tire.

There are two main constructions: - Self-supporting run-flats: Reinforced sidewalls carry the vehicle’s weight when air pressure is lost. This is the most common design. - Support ring system: A rigid ring mounted to a compatible wheel supports the vehicle if the tire deflates. This design is less common and requires specific wheels.

Because it’s harder to tell when a run-flat is low on air, they should be used on vehicles equipped with a tire pressure monitoring system (TPMS). Learn more about TPMS and how to check tire pressure.

Some vehicles come from the factory with run-flats and do not include a spare tire.
