Rolling StockMan, were we ever impressed with the ride quality of the Goodyear AT-Ss. They're every bit as quiet as passenger car tires, really stick to the pavement, and feature two wide circumferential grooves for good wet weather handling (and we did try them in wet weather, believe it or not). Off road, they bit into loose dirt without digging and worked very well in the sand. They give really good bite around corners or on dirt roads and claw and grab when climbing loose dirt or sandstone hills. They are very soft, however, and feature Goodyear's older, more vulnerable two-ply sidewalls so we didn't air them down for rocks.
We've spilled brake fluid on the wheels, coated them with brake dust, and slathered them in alkaline mud and they still look great. The finish has held up, but the best part is that they contribute to the wheel/tire combo, being 5 pounds lighter than the stock steel wheels with 31s.
