As long as they stay on the rear wheels, the only "problem" is that your Jazz has grown 5,5 millimetres higher at the rear.
If they were on the front wheels you would get a speedometer deviation of 1.8%, 120 kmh on the 185/55R16 becomes slightly more than 122 kmh on the 195/55R16.
However, I have no idea how it is in
Sweden Romania or Ukraine with the regulations regarding type approval, whether your Jazz still meets the legal requirements and how your insurer would react on the "not original" size.
PS We see such a lot of
blue-
yellow here in Poland and I still thought Sweden?
