NOTE: if you have to tackle any sizable or long hills, all bets are off.
And for heaven's sake make sure your all-seasons have lots of tread.
Okay? are you kidding. There are all kinds of videos proving winter tires stop WAY shorter than all season tires on snow AND cold pavement. You are going to go through two (at least ) sets of tires in the life of your car so why not make one of them winter so you don't put people around you at risk.
