My first set lasted 70,000ish miles but were basically slicks when I replaced them. I currently have 11,000 miles on my second set and they still look new. I have 285/75/16's on stock rings the first time and now have a 285/65/18's on a 9in wide rim. They fit and look much better on a wider than stock rim.
The first set had maybe 5000 miles worth of towing and the second set has seen no tow duty.
