Volkswagen Polo Service & Repair Manual: Run-Flat Tire, Overview of a PAX Tire

PAX tires involve specially developed system that exhibits the following differences in comparison to conventional tires:
Pax Tires with Supporting Ring
–  -I- PAX tires with air
   
–  -II- PAX tires without air
–  The tire is anchored to a special rim that prevents it from sliding off when pressure is lost. The rubber supporting ring ensures stability in emergency operation.
The inner and outer bead diameter are different sizes. This makes it possible to place the tire in a supporting ring.
The tire is anchored to the rim differently.
In this way, the tire height could be reduced considerably. That was possible because the area near the bead could be considerably smaller due to the special connection between the tire and rim.
The tire bead is formed so that it can engage in the rim seat. Therefore, it remains firmly in the seat when pressure is lost.
