| PAX tires involve specially developed system that exhibits
the following differences in comparison to conventional tires: |
| Pax Tires with Supporting Ring |

-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. |

| The secure seating of the tire in the rim is ensured in all
driving situations due to the type of construction. |
| A wedge-shaped component of the tire is pressed between the
bead bundle and rim when loaded. This happens independently of
the pressure in the tire. |

|
| In contract to conventional tires, tires with emergency
running characteristics (PAX) exhibit differences in regard to
dimensions and designations. |
| Therefore, PAX tires can only be mounted on special rims (PAX). |
