Volkswagen Golf Service & Repair Manual: Run-flat tyres, structure of a PAX tyre
| Run-flat tyres (PAX) are specially developed tyres that
differ from conventional tyres as follows: |
| PAX tyre with support ring |
| – |
-I- Pax tyre with regular tyre
pressure |
|
|
|
| – |
The tyre locks in place on a special wheel rim which
prevents the tyre from slipping off in case of pressure loss.
The rubber support ring ensures proper stability when driving
with a flat tyre. |
| The inner and outer bead diameters differ in size. This
makes it possible to add a support ring inside the tyre. |
| The tyre is secured differently to the rim. |
| This allows the tyre height to be greatly reduced. This was
made possible by the reduced bead area due the special
connection between the tyre and rim. |
| The tyre beads are formed such that they engage in the rim
seat. Therefore, the tyre remains firmly secured to the
wheel/rim even when there has been a loss of inflation pressure. |

| Construction of the bead area for a standard tyre |
|
|
|
| Construction of bead zone on tyres with run-flat capability
(PAX) |
|
|
|
| Seating of tyres with run-flat capability (PAX) |
| Due to the construction of the tyre, it remains firmly
attached to the wheel in all driving situations. |
| A wedged-shaped component of the tyre is thereby pressed
between the bead core and rim by the load. This occurs
regardless of the tyre pressure. |
|
|
|
| Dimensions of tyres with run-flat capability (PAX) |
| As compared to standard tyres, run-flat tyres (PAX) have
different dimensions and designations. |
| Run-flat tyres (PAX) can therefore only be fitted to special
wheels designed for the PAX system. |

Width in millimetres: tyre width from sidewall to sidewall
on the standard rim (corresponds to the width dimension on
standard tyres) |
