But for a daily driver, all-season tires will do just fine as the snow doesn't stick very long.[/b]
I disagree. Since rubber in all-season tires was formulated to work in ALL seasons, it therefore doesn't work really well in ANY season. Just like how a good summer tire works well in rain and dry pavement when it's hot, it sucks in the snow and dry pavement when it's cold- I drove on a set of worn autox Azenis RT-215 year round in Kansas one winter, so I have a fair amount of experience. An all season tire is a compromise across the board for all conditions while summer/winter tires are more purpose built.
A good winter tire will keep its rubber soft and pliable in the coldest conditions- allowing the rubber to deform and grip the road surface much better. A summer tire's or all season tire's rubber will get hard when it gets cold. In dry conditions below about 45 degrees, a winter tire should be able to out-brake an all season tire. And as the temps get colder, the winter tire will do better and better compared to the all season tire.
Last winter was my first winter on a winter tire. I was amazed that when I hit the brakes on ice or snow packed roads, the car would actually slow down- almost as if I was on dry pavement. The same car during the previous winter on all seasons, I would have to fight wheel lock up all the time when braking. Winters in KS are filled more with ice than snow. The driveway at my house in KS was sloped pretty good. If I stopped midway on the ice packed driveway with all seasons and then tried to resume up the driveway- lots of wheels spin and usually only backward motion. I'd have to get a running start from the street to have a chance at making it up. With winter tires, I could stop midway just like the previous winter, but actually climb the driveway from a stop.
Sure, millions of people drive through each winter on all season tires (and some on summer tires) and don't have any issues, but I like having the added safety and confidence that a dedicated winter tire offers.
