TIL that placing even so much as make, model, and year in your profile, but even something as easy as a state, you're giving the world all your personal information AND will have your identity stolen.
Either way, with your attitude you won't go far. The "winter tire" subject is MORE then adequately discussed on this site. You didn't want anything but a spoon fed answer to stop you from researching from yourself. Here's the short and sweet. All seasons may be alright for winter, but a winter tire will perform better in freezing temperatures and snow. Simple. An all season will lack the performance in the winter because it's designed for year round use. Will you die not having winter tires? Not if you know how to drive. Will you be better off with winter tires? Likely.
