Do you put snow tires on your car for the winter or just good all season ones? My car is a Kia Sedona minivan that we bought last March so this will be the first winter with it. Normally, I just use my regular all season tires but am wondering if I should invest in snow tires. We plan to spend time in NH skiing this winter and I wonder if the snow tires would make it safer and easier to get there in bad weather? Do you think they are worth it?
