I am going on 3 winters driving my fire in Wisconsin. DO have Conti's on it, never had to put weight in the back, but may try it this year. I wish I was in the position to put it up for the winter, it sure breaks my heart to see her covered in snow, and ice, at least she can warm up at night in the garage. I have a very short drive to work, but could not see taking her too far out of town.
