Just got my P8 (love it) with 20” wheels and was curious if anyone has driven in the snow with chains yet? I read in the Volvo owners manual that Volvo doesn’t recommended using chains on wheels larger than 18”. However, Volvo lists and sells chains for my P8 with 20” wheels. Additionally, my dealer had me sign a document that I would not use snow chains on the vehicle, but they sell the snow chains for my vehicle. A bit confusing, any insight here?
