Hello. I’ll get back here after a long time. So it’s about the following: The cold season has caught up with us very quickly. That’s why I need a set of new winter tyres with new aluminium wheels now. Now my question: Absolutely original from Mercedes Benz or can you just buy from the big tyre dealer next door? I don’t know about technology, but how exactly does the tyre pressure control work? Is this somehow with the tyre Is that why you can only change the original tyres with MB incl. aluminium? Questions about questions..I know.. Maybe my concerns are also absolute nonsense Well anyway. Thank you for your answers and everyone a nice Christmas wishes Christian, who is still very happy with his R-Class.
