Hi, because I don’t really know much about tyres, I ask my question here: So I drive a Mazda 121 (JBSM Bj.2000 -> Abklatsch from the Ford Fiesta). In the vehicle license are tyres of the size 185/55 R14 which are at the moment also as summer tyres on it (on standard steel rims). But I still have almost new 175/65 R14 winter tyres from my Honda, which recently landed in the press. Now my question is now whether I have these tyres (or possibly on I heard a “no” from the “friendly” and word-carrying Mazda dealer, at ATU they told me: “Only winter tyres 165/65 R14”. To hear something somewhat reliable I am to the TÜV. The nice gentleman there gave me an expression for a pocket money with serial tyres of my car (see file in the appendix). Is this now something official or is it enough for a check the Zu if I have the note in the car? Do I still have to have the new tyres registered with the TÜV? As I said: I don’t know much about the topic and I therefore rely on your help Cheers, Martin
