There is a Hill in the Hammer that l went up in 2 wheel drive with snows on and could not make it up. In my Old Blazer, Got out and put in 4X4 and away we went up the hill none stop. Always be with them on now come winter. If you get a Discount from your Insurance and you get in an Accident with out the Snows on they will not cover you as it caused the Accident in Their Eyes. Please Remember That??? That is why I have 4 Basically Brand New less than 500 km for Sale of my Old Vehicle that I bought and then Scraped.
