Self Supporting
One of the technologies used in run-flat tyres is the self support kind.

Self-supporting run-flat tyres are now common on light trucks and passenger cars and typically allows the vehicle to be driven for 50 miles (80 km) at around 50 miles per hour (80 km/h). However, if the tyres are subject to misuse, wheels may become damaged in the process, and repair may be impossible or unsafe, especially if the tyre is punctured in the sidewall or at the edge of the tread.

They carry a 20% to 40% weight penalty over similar standard tyres and the thicker sidewall also means higher rolling resistance, which reduces the vehicle's fuel economy. However, the weight penalty of the individual tyre is usually more than compensated by the fact that the vehicle need no longer carry a spare, as well as the equipment needed to swap in the spare. The thicker sidewall however results in more road imperfections filtering through the tire to the rim and hence to the car, which results in a harsher ride.

Now you know

You have most probably heard of run-flat tyres. The ones 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.

Did you know there at least three types of run-flat tyres?
