Nike, I've never ran a snow tire on my coach! I run straight highway tread (Michelins) and, I've drove from the Grand Canyon, AZ. (5000' elevation) 3/4" of snow on the roadway to Flagstaff, AZ. (7,500' in elevation) 1-1/2' of snow on the roadway one mid April Spring day when a surprise snowstorm came thru Northern Arizona. I drove very slow and never spin a wheel. Motorhomes are very heavy on the drive axles and plow thru the snow pretty well! My coach was brand new at the time and I didn't have chains. I ended up spending the night in Phoenix, AZ. drove until I was out of the snow! I just drove according to the conditions! Good Luck, John
