Technical Requirements
- The wheel and tire combinations or retrofittings listed in the individual vehicle tables refer exclusively to original disc wheels.
- Approval of wheel/tire combinations or retrofittings with disc wheels from the accessories trade is not possible with the accompanying parts certificate.
- Tubeless radial tires may only be used with stepped rims with a bead retaining contour, for example a round hump.
- Run-flat tires (reinforced sidewall) may only be used on disc wheels with extended hump and vehicles with a tire pressure monitoring system.
- It is mandatory for run-flat tires to have a tire pressure monitoring system in the vehicle.
- The correct tire inflation pressure values must be observed when the specified wheel and tire combinations are used. The tire pressures are listed on the tire pressure label on the inside of the fuel filler door and on the driver side B-pillar.
- Sufficient clearance between the wheels and tires and the wheel housing-, suspension- and brake components is ensured if the instructions and conditions specified in the approval certificate are observed under all operating conditions.
- If not otherwise specified, snow chains may be mounted only on the drive wheels. If the vehicle has AWD, then snow chains may be used on the front wheels only.
Additional Wheel Housing Enlargement, FLAPS
On some vehicles with certain wheel/tire combinations, wheel housing enlargements (FLAPS) must be attached on the fenders or bumper for certification/technical reasons -arrows-.
Please check whether FLAPS must be installed.
The necessary wheel/tire combination information can be found in the overview table for the respective vehicle.
