I drive an '08 Dodge 2500 4X4 Cummins Diesel in Ontario, Canada. I now have 30,000 miles on these tires and have driven in all four seasons. I have seen light and heavy snow, rain, dry pavement, wet pavement, and temperatures from very cold to very hot. This is what I have observed so far: overall, these tires perform exceptionally well. They are very quiet, excellent in both light & heavy snow and great traction on dry pavement (especially when I compare them to my O.E. BFG Rugged Trails !). However, they do have shortcomings: treadwear seems to be wearing out quicker than they should despite my average driving (not aggressive at all), and they have mediocre wet pavement traction in my opinion. If you live in any upper US State that gets snow, or anywhere in Canada, you will not be disappointed with how these tires perform in snow and on ice.
