I raised my winter tyres last week with my Smart, thanks to the many instructions here in the forum no problem. Now I read, because I want to change the WR also with my golf always what centrings made of plastic/plastic which are probably mandatory with the Golf V, if one installs an accessory alufelge. Is there such a thing for the Smart also or is simply the summer bike put down and then the WR on it? Was there no problem with me. PS: I still have one question, I h no problem to solve 10 screws with a normal ratchet and then turn out with the hands, but with 2 screws I had to use the ratchet completely to get the screws out, while screwing in the same problem, the screws went incredibly hard compared to the others, should I change with the problem to SC? And what will they tell me, if I want to do this on guarantee (EZ 04/09), because I did this myself with the.
