| Self supporting tyres (SST) with run-flat capability |
| Removing and fitting run-flat tyres → Chapter |

Note | t
| SST tyres may only be fitted to vehicles which have a tyre pressure monitoring system. The system warns the driver if the tyre pressure drops below a specified level. |
| t
| Tyre damage and the resulting loss of pressure are not readily visible. |
| t
| In the event of a total loss of pressure, it is possible to continue driving for up to 50 km at a maximum of 80 km/h. |
| Note the special installation instructions for SST tyres. |
| It is not permitted to fit both SST tyres and standard tyres on the same vehicle, even on separate axles. A standard tyre can be fitted only in exceptional circumstances for a brief period and limited distance. The driver must be expressly informed that the SST run-flat characteristics do not apply in this case. |
| In the event of a puncture, it is the responsibility of the driver to check the affected tyre or tyres and decide whether it is possible to continue driving. See → Owner's Manual. |
| Use only the approved type of wheels for retrofitting (EH2 extended hump rim contour). |
