I have Mud & Snow tires on my coach, and if the roads are slick it doesn't move!
Tire chains? Best check to see if you can safely use them. My first coach years ago had the water system low point drain valves in the rear wheel wells. A broken cross chain (not at all uncommon) would have stripped them out very neatly! Also, remember the speed limitation when using tire chains. Many chain manufacturers say 25 or 30 MPH!
When there is snow, I don't go! Not in the motorhome, at least. In the other vehicles, sure!
