Personally, if the weather is bad enough that I feel the need to have studs or chains, I will stay home. I drive an hour one way in good weather. i am not going to turn it into a 3 hour each way ordeal dicking with slick roads and stupid people. I have a F250 4x4 with a power stroke diesel and serious off road/mud/snow tires. The kind that make road noise that will bore a hole in your brain after an hour long drive... it's not worth your life folks. It's just a job. The part that sucks is getting stuck AT work. That is where things quickly go to hell in my life...
