When it snows I usually cover my garage door with snow from "peeling out" in my driveway. I happened to notice yesterday that my driveway has some strange grooves in it. I guess this is why the DOT doesn't let you run studded tires year round.
Sorry to see your driveway like that. Studded tires aren't necessary, unless you're living in Antartica. I drive around with my winter tires, and enjoy them very much... they aren't too much better in ice grip though.
