I have these tires too, and so far they have been great. i live in Michigan also so I know about our winters, and I go to the sand dunes just about every year. No complaints at all. I went to Discount tire and got them installed with warranty for $735 (helps to know the manager). I stuck with the original tire size only because the wider tires are worse in different situations, and the extra width that hangs out of the wheel well really gets the side of the truck dirty. I like getting muddy, but when you spend the time to wash it, and its ruined because you drove through a puddle, it kinda sucks.

 

I love my coopers!!! Awesome tire! Great wet performance!
