If your looking for more economical tires Liberator AT. You can get them at wally world or i think sams.

I work at walmart, in the bays. The liberator is the best truck tires they sell. quiet on the road, grip good off. snow is a breeze, and ice actually is passable. (Personally i think no tires rock on ice unless they are studded)
rubber has good grip, without being too hard
big clean outs to clean the tread in mud/snow
good sipeing for traction in water/ice

sipe = little cuts in tread

I live in MO, and have 4 inches of snow on the ground now, I am currently running them and have no complaints.

50,000 mile tires, yet they last usually more like 60,000 if you maintain them (rotate/proper inflation)
