Hello, I’m new here in the forum. I also have a question or a problem: I bought a 1 golf cabrio last week and a few days later I noticed that the matures that the cart has on it (205/55R15), according to the registration certificate part I are not registered (there are only 175/70R13 registered). I have now read in the internet that there are still so-called coc papers on which there are possibly other sizes. however, I did not notice these when buying and I doubt that the dealer still has them. so: I’m driving around with unregistered matures. in addition, the fact that the matures in a driver’s and co-driver’s curve or in a bottom wave at the back strip the wheelbox… (I wonder how to put such flaps on it then…) now is the question what I’m doing. I got matures from my mother with the size 170/65R14. first question: do they fit on my rims at all? and then make sense of it. to have them entered? or can you have these coc-papers or similar copied somewhere (tüv o.ä.) on which the other mature sizes stand? many thanks already for your answer. mz1202
