Hello together, what is this really like, on the car the Wi-tires are mandatory from now on! And what does it look like with the car trailers?? I have a braked double axle trailer (pitch) …. can I drive with the (he has summer tires on it) then e.g. at all now?? e.g. to get wood, etc. ?? Or does the law apply exclusively to cars – i.e. vehicles with motor? Does anyone know that? Thanks and greetings Jürgen
