At the wear bars and worn quite unevenly at just shy of 25k miles. Of those 25,000 miles, about half was on interstate and about a quarter more on two lane mountain highway. I'm very disappointed in these tires.
I've kept the pressures dead on vehicle spec, checked monthly, and rotated every 5,000 miles until 15,000 when the uneven wear was so pronounced that I decided to just run them where they were because rotation wasn't actually doing anything for me. These tires have about 100 miles of sane and sedate off-pavement travel, and weren't abused at any time. The vehicle is mechanically sound, perfectly aligned, and got new Bilstein shocks right after the first rotation. I haven't towed anything since these tires went on, and have never had more than 500 pounds in the bed.
The Snow rating I've given as a three indicates performance when new. Last winter was nervous even with 300 pounds of dead weight in the bed of the truck.
