Hello, I recently enjoyed the FL5. I would also like to drive the car in winter, but frankly I have no idea at all which rim size+tire size is best taken here. Apparently, many of them drive a little less wide 18-inch instead of 19-inch in winter. I found them quite chic here, but, as I said, I don’t know if this fits (although you can enter the car in the search):https://www.felgenshop.de/…/ Another question is whether you can also use the e Original wheels from the FK8. They are used quite cheaply and for the first winter they would be enough. Here are some data of used FK8 winter wheels, which I could find in the net: Tyre size: 235/35R19 91W Wheel data: Part number:5F0 601 025 AA Size: 18 inches Width: 8.5Jx19 ET: 60 Hole circle: 5×120 Another (probably stupid) question is which RDKS system the FL5 has. As I see it, it should be a passive one. In my documents I find only the name “DWS” and that’s it. Thank you for your help! MagnumPI
