This kind of weather must be quite exotic for you?
I have drove with summer tyres in snow sometimes, and .. it is not fun. Braking distances are quite mad.
In fact, driving with good (nordic) winter tyres is fun. Grip is good. This morning seems to be sunny again, and nice -27celsius was when i turned key in my winterbeater.
Yesterday was first day of the 2018 when you are allowed to drive with summer tyres here. But we have to wait 1 month minimum because we still have 40cm of snow and really cold weather..
