Very disappointed with these tires. The AT2 performance is dismal compared to the original AT. Feels like driving on ball bearings on gravel roads. Traction on packed snow or ice is so bad that the rear tires spin as soon as the brake is released if there is any incline at all. Have to use four-wheel-drive to get up the driveway unless the concrete is completely clear. Traction in deep snow or mud is almost nonexistent. Cannot climb out of muddy ruts and six inches of snow brings the truck to a halt, even in four-wheel-drive. Never had to pull out the chains when I ran the old ATs but they are showing wear from all the use with these AT2s. Traction was good on the slickrock out in Utah but traction on loose sand was only slightly better than mud or deep snow. It looks like they are on par with the original ATs in terms of tread wear. Got 85K out of the ATs and the AT2s have worn about 25 percent in 30K miles. Performance on dry roads is generally good but there is a noticeable sway on grooved concrete highways. Performance is consistent whether the truck is empty, carrying a full load or towing.
