Hello, Could someone mail me such a certificate of approval? 205/55 R16 May they be allowed on the original Volvoalu bikes? Where else a 205/50 R16 is on it. Do I always have to carry the approval or do I have to take it from the TÜV somehow / registered? Greetings Peter and thank you very much (Volvo 850 Kombi 2,0 126PS switch Bj.11.96)
