You may want to check out the Michelin LTX M/S2. It's a great highway tire and the snow traction is superb. I have them on my F150 and I'm extremely pleased. They are quiet, smooth, roll forever, and the wet and snow traction is quite good.
I will warn you, they are a bit pricey, but worth their weight in gold. This is my 4th set of Michelins on 3 different vehicles.
