Run-flat tyres, retrofitting/requirements when using run-flat tyres

~1min read

Caution Retrofitting run-flat tyres to vehicles may only be undertaken if the tyres are fitted as standard or they are available as an option.
These tyres may only be used on vehicles with a tyre pressure monitoring system as a pressure lose in the tyres is not always visible. This system warns the driver when an inflation pressure is less than a certain inflation pressure.

Permitted are:

Direct measuring systems → Running gear, axles, steering; Rep. gr.44

Indirect measuring systems → Running gear, axles, steering; Rep. gr.44

Tyres with run-flat properties may only be fitted on disc-type wheels with raised double hump (Extended Hump - EH2) → Chapter.

Adhere to the special assembly instructions → Chapter.

A mixed installation with standard tyres is not permitted, even on same axle.

Only in exceptional circumstances may a standard tyre be fitted e.g. for a short period or a limited distance. The special run-flat characteristics are lost, the driver must always be informed.

Please observe the recommended tyre makes → Wheel and Tyre Guide; Rep. gr.44.
