Most of the AT tires are fairly quiet, but don't necessarily stay quiet as they get some miles on them (stock BFG AT come to mind). Generally speaking, the tighter the tread blocks, the quieter the tire will be, but it can also depend some on what roads you drive (composition of the road). I don't have any personal experience with the Continental Terrain Contact A/T, but Mercedes Benz often specs Continentals on their G Wagons, and they are pretty quiet. They make the A/T in the stock Raptor size, and the tread blocks are pretty tight. You might give those a shot. Lots of guys run the Falken Wildpeak AT3W as well, and they have slightly larger spacing in the tread block than the Continental, but probably still tight enough to keep it fairly quiet.All of that being said, correct alignment, proper inflation, and regular rotation will go a long way to keep a tire wearing properly, and thus as quiet as possible.
