Tires with Run-flat Properties
Item | Description |

B | Tire with run-flat properties after pressure loss |
1 | Wheel position with correct tire pressure |
2 | Wheel position with insufficient tire pressure |
3 | Tires |
4 | Reinforced sidewall |
In addition to the standard tires, run-flat tires are also optionally available. These tires have a reinforced sidewall and provide the advantage that the tire maintains its shape to a large extent even in the event of insufficient tire pressure. This ensures that the vehicle handling remains stable.
Advantage:
Special wheel rims (EH2) and a tire pressure monitoring system are needed for run-flat tires.
Standard tires can also be installed on the EH2 (EH = Extended Hump) wheel rims. Tires with run-flat properties have the same size code and the same appearance as standard tires.
With some tires, the code RF for run-flat is included in the tire designation, e.g. 205/55 RF 16.
Tires with run-flat properties have various different codes on the sidewall, depending on the manufacturer.
WARNING: If a tire with run-flat properties is used without air then the vehicle speed must not exceed 80 km/h and the vehicle must not be driven for distances in excess of 80 km.
Note: Vehicles equipped at the factory with run-flat tires do not feature a tire repair kit or a spare wheel.
