For what it is worth, I bought these tires when I was living in Dayton OH. in 2008.Now its 2012 and they have 45-50000 miles! After gitting into snow there with my Ultra High Proformance summer tires i did some research and found these. . Thay handled the snow there perfectly (city and country roads),for the three months I was there. Then I pulled a ATV trailer (in the snow and ice) to Virgina. While in VA. I did mostly hiway driving, with trips to DC ect.for three months. Then pulled the same trailer to Florida., then to Alaska. while in Alaska (for a year) they saw meny miles on dirt and gravel roads, snow and ice. Alaska isnt known for the best road surfaces. Then Back to FL. where there still getting miles put on them. All that out of a set of snow tires.
