Definition of Conti SSR

Continental SSR tyres are self-supporting run-flat tyres that allow drivers to reach a safe destination despite a puncture.

Conti SSR tyres have reinforced sidewalls that prevent the wheels from collapsing in cases of air pressure loss. Self-supporting run-flat tyres keep the wheel rim off the road, and allow continued driving for up to 80 kilometres (50 miles) at 80 km/hr.

Because SSR tyres ensure comfortable driving even after a puncture, the driver might not notice any loss of air pressure within the tyre. That is why self-supporting run-flat tyres should only be used on vehicles that have a tyre pressure monitoring system (TPMS), which alerts the driver to a problem via the dashboard instruments.

These tyres were developed jointly between Bridgestone and Continental in a project announced in 2002 and represent a major breakthrough in driving safety.

SSR tyres, or self-supporting run-flat tyres, prevent the destruction of the tyre when air pressure is lost because an affected tyre is not crushed between the wheel rim and the road. Further, SSR tyres eliminate the hazard of changing a flat tyre at the side of the road. For anyone who has suffered a tyre failure at speed, or had to change a wheel on a motorway hard shoulder, the safety benefits of this technology will be clear enough.
