Hello, New to the group here living in Rhineland-Pfalz, Germany. I am soon to be a 2019 GLC43 owner. As I am due to receive it in the next month I was wondering what size range wheel the GLC43 will accommodate? It will come with the 21" wheel and performance tyre, and there are no winter/all season tyres available for that size I was wondering what people are using for the winter months. We do not get an excessive amount of snowfall, but slush and black ice is common when it does. Any feedback would be appreciated.
