Self-Supporting Run-Flat Tires (SSR)

In the event of a loss of pressure, run-flat tires can still function reliably over a certain distance at a specified top speed. To make this possible, the sidewalls of the Self-Supporting Run-Flat Tire (SSR) are reinforced with extra rubber to absorb the weight of the vehicle should inflation pressure drop. In many cases, this enables the motorist to reach the intended destination or at least make it to the nearest automotive repair shop.
