A run-flat tire/tyre is a pneumatic vehicle tire that is designed to resist the effects of deflation when punctured, and to allow the vehicle to continue to be driven at reduced speeds - under 90 km/h (56 mph) – and for limited distances – usually 16 to 80 km (10 to 50 mi), depending on the type of tire. If the vehicle has a run flat, the Is Run Flat field can be marked.
