Hello, I had the last winter wheels mounted. At the back the track plates should be removed. There are 20mm plates, these are attached with screws(17 SW) to the vehicle, then the wheel is screwed to the track plate. Now the impact screw has not been fixed correctly and on both sides is each one screw completely round (it was then tried with a 16er nut the disaster still to avert, but also that went wrong). The 2 screws are now completely round. Now everything has been screwed again and the winter wheels are mounted so. How could I remove the track plates best? My solution would be chiseling on or with a slip the head of the round screws (and a part of the distance disc which is then in the way) flex and then remove the plate. To chisel however, I think that such blows, which then also hit the wheel slash is not good at all. If that works with the impact disc and then you take off the disc, is still the question if the screw can be turned off so easily from the wheel scar. However, for example, I would have made the most sense of the tension.
