Emergency Mobility Systems
If a tire punctures and loses air, a standard size or a temporary spare tire must be put on in order to continue the journey.
In order to avoid the troublesome, sometimes dangerous, procedure of changing a tire on an open road, various manufacturers now offer so-called emergency mobility systems.
What these tires have in common is that when all air pressure is lost the rim does not destroy the tire. The journey can be continued without changing the tire – over a limited distance at a restricted speed.
