I have Cooper AT3 XLT for spring,summer, and fall- they're severe weather rated and quiet on the highway while towing, but, they tend to pickup pebbles. I don't run them in the winter just because I don't want to ruin my wheels, so for winter tires I run Nokian Outpost A/T and they're very quiet on the highway, have a nice tread pattern, and offer great traction.

I replaced General Grabber ATX and they were okay but got a bit noisy for what they are and I hate the flat spots they develop when parked in the cold. I've also used Falken Wildpeak AT3W and they were good all around and quiet but they got pricey.
