This question already has an answer here:
I live in East Tennessee where the winters are generally quite short. The roads can be very icy and snowy during the 2-3 months of winter- but usually only for short periods. I was told that if I buy snow tires, they will wear out quickly from driving mostly on the asphalt, and that they may even be worse than all- season tires on wet roads- which we do have a lot of. It appears that most people living here don't have snow tires. I have an old Mazda Protege which doesn't have much traction in snow or ice, and which I don't believe has anti-lock brakes. I now need to buy 4 new tires. Should I go with snow tires, given the lack of consistent snow, or would all- season be enough.
