Run Flat Tyres
A run flat tyre is a pneumatic vehicle tyre 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 56 mph (90 km/h) – and for limited distances – usually 10 mi (16 km) to 50 mi (80 km), depending on the type of tyre.
WHAT ARE RUN FLAT TYRES?
This kind of tyres are tyres on which you can continue driving after a puncture so you can take time get to an auto shop or find a safe, level area to change your tyre.
You can’t drive on them indefinitely, though. Check the manufacturer’s specifications to find out how fast and how far you can drive on your run flatt tyres. Bridgestone run-flat tyres will allow continued operation even after a loss of some or all inflation pressure for up to 50 miles (80 km) at a maximum speed up to 50 mph (80 km/h.)
HOW DO RUN FLAT TYRES WORK?
There are two primary types of run flat tyre systems: the self-supporting system and the support ring system.
In most self-supporting run flat tyre systems, the tyre features reinforced sidewall construction that will continue supporting the vehicle in the event of air loss. This construction allows continued operation after the loss of air pressure up to the speed and distance specified by the manufacturer.
