First set of tires that I have ever owned that have lasted beyond 100,000km's ( 62,000 miles ). To me that says alot as 30,000km's ( 18,000 miles ) of that was gravel which has a tendency to chew through tires. In the three years I ran them not once did I get stuck which would include snow, mud and ice. I was not a tire rotation guru either ( maybe 3-4 times over the 100,000km's ). I am giving these serious consideration again as a replacement set but I am also considering Continental CrossContact LX20 with EcoPlus Technology as they seem to be getting great reviews comparitably.
Also, live in Alberta, Canada - Not Montana as listed.
