Hi people. I need help about the type of tires I should use with the MZ 251. I have bought this tires: vor reifen: Metzeler Hinten reifen: Continental
But the problem come with the hinterrad Continental reifen size. My papers say hinterrad: 110/80-16 and I have bought the 3,50. So the man von TÜV say me that I need a paper saying that I can use the 3,50 reifen. My motorrad is of 7/1990. Where and how can I get this paper???
