Hello, I had a TÜV appointment yesterday. Unfortunately, I was not assigned the badge because the ALU rims of my winter bikes were not equipped with a metal screw valve. According to ABE, in fact, the same metal valves are prescribed, because my vehicle can drive faster than 210 km/h. I wonder if the tyre dealer should have known that. As a layman, to whom I am quite counting, one does not necessarily pay attention to something like this. I also wonder, however, that the aluminium F my summer bikes also have a rubber valve, and that already factory side. Who has had similar experiences? Greetings Michael
