I used the LT235/85R-16E XPS Ribs both on my 2002 3500 dually and a previous Jayco Designer XL 3610RLTS 5th wheel. Never a tire problem, and yes, I used them year round (albeit the winter use was primarily in Texas). I highly recommend them.
Obviously, the tread pattern of the XPS Rib isn't that of a snow or off-road tire. There's the XPS Traction drive axle tire for that.
