Not sure what size you are looking for, but Goodyear Wrangler Trailrunner AT tires are a good AT tire at a great price in the 275/65 R20 size. For whatever reason, in other sizes the price difference may not be as big. With a smaller difference in price, there are better tires for the money out there like some listed here like Duratracs, BFG K02s or Falken Wildpeaks.
Trailrunner AT is not as aggressive as the Duratracs. Duratracs are a better tire, if you don't mind some road noise once some miles are on them. There are a lot of other better tires listed here as well. But for the money, and for occasional offroad use, don't sell the Trailrunner AT short. And for whatever reason, they are a bargain in the 275/65 R20 size from what I saw.
My RAM spends 95%+ of it's miles on pavement and I don't haul real heavy, or tow really big stuff. Trailrunners are way underrated for occasional dirt road / back road / snow use. In this size they are Load Range E / 3750 lbs and they are 3pmsf severe snow rated. If you look at the AT Tire comparison ratings, they are not the best in any one category, but they are rated pretty highly in all categories, and are very quiet for an AT tire.
