Just an FYI, the AT3 XLT has passed 3PMSF (severe service rating or "snowflake rating") in a number of sizes. However due to the nature of the conditions when testing, they haven't been able to certify all sizes yet. Because of that, they haven't all been branded with the logo. But the tire, the design, and the compounds have passed the test already, so it's effectively a snowflake rated tire. That's straight from Cooper as I am performing a long term wear test for them on these tires.
Here in Washington, when the "Chains Required" sign goes up in the passes, you do NOT have to chain up if you have AWD or 4WD and your tire is marked with M+S, 3PMSF or All-Season. The state police have started pulling drivers over to check their tires to make sure they comply with the law - it's like a $300 ticket to not have the proper traction tires. Cooper's website does list the tire as All-Season, but I'm not sure that's an argument I want to have with a state trooper on the side of the highway. I am still leaning that direction though. This tire ticks literally every other check-box I have.
For what it's worth, your article on Trail4Runner was what originally sold me on the XLTs.
