I've been running 31x10.5 ProComp Xtreme M/Ts
for about six months now and they're great. Very smooth on the road and still have nice agressive tread pattern.
Pro Comp Xtreme Mud Terrain Radial Tires - Mud Terrain Tires, Off Road & Mud Tires
For snow driving they would probably be better than the A/Ts because they're siped.
I'd originally ordered the Xtreme A/Ts but they were out of stock. I think the price difference was like an extra $100 total with the 4 ot 3 deal. Not sure about the difference over the regular A/Ts
