After a few weeks ago I bought a Opel Corsa D GSI (my friend thinks that the first signs of a midlife crisis… 🙂 ), I slowly think about what to buy of winter bikes. According to the catalog of standard tyres I can drive 6Jx16 with 195/55 or 205/50, whereby snow chains are only allowed with the 205ers. Thus the 195ers fall away for me. (I don’t buy any winter bikes in a size of which I’m from At the beginning I know that I can never mount chains…) So the easiest thing would be to clamp 6Jx16 steel wheels with the 205/50 on them. Now I have a white Corsa D with panoramic roof and the black roof is really good in contrast. And since it’s recently (people, I’m just about 40 and no longer up to date… 😉 For me, the “new but”… 🙂 ) is matt-black light-metal wheels, which I think are pretty cool, I’m thinking about whether I shouldn’t treat myself to them. I did a little research on the internet and found matt-black rims from Dezent, Ronal and Magma. I only have the following problem: The rims from Dezent and Ronal are 7J or 7.5Jx16 and according to the report should be arranged on the rear axle for this?! Can this be? Although I ride summer bikes 215/45 R 17 on 7Jx17 as standard, for winter bikes 205/50 R 16 on 7J or 7.5Jx16 must still be arranged? Is there a professional here who can explain this to me because of Ma I don’t want to go wrong. I had an “experience” many years ago with a black Opel Corsa A and I don’t want to push the same money into the hands of a paintmaker again, what the wheels cost… As I see it, the Magma’s in 6,5Jx16 are the only way, because you don’t have to find out about them. I know, I know, I could ask the next friendly tyre dealer, but this forum offers itself. And I haven’t been talking in a while… well, I’d be very happy about some interesting answers.
