doxiemom11, I have a set, used them in North Carolina years ago so yes they can be useful. There have been threads on these boards about them being required in ore, wash I believe. Have the set for my F350 and will put in the rv if we suspect travel to a winter storm area. I have seen chains on tires in Mi, as we have family there. When a kid we moved from UPSTATE NY to Tenn, and when we left NY (plattsburgh) there was 3 ft of snow on ground and it was snowing. Got to Tenn it snowed and then froze, out of school for 2 weeks! Some states just not prepared for winter storms and aftermath.
