The Duratrac is a good aggressive Winter tire. I had that tire on a 2018 ZR2 which of course is nothing like what your running it on. I can say that off road in the Winter that tire is totally impressive. I doubt it would last more than 35K and still have meaningful tread left pulling that kind of weight. However, that is about 3 years away and that may be a better way of looking at it. There are times when the miles you get on a set of tires are important. There are also times when the performance of the tire matters more. If your traveling at 9500 ft through the winter, I would chose a really good Winter tire. I am happy with the Falcon Wild Peaks. They are not as aggressive as the Goodyears, but they are a good Winter tire. We spend 6 months of the year in snow, and few buy Michelins.
