Check out the Cooper Discoverer ATPs. Basically what you are looking for is something with a lot of siping. Most tires can be additionally siped for an extra fee, but I don't think that you want that extreme. The siping allows for evacuation of water in wet conditions, and it also becomes clogged with snow in snowy conditions, giving better grip in the snow. It is much easier for snow to grip snow than it is for cold rubber to grip snow. I have the BFG AT KO and while they were alright in snow and rain, I will not be getting them again due to their poor balancing ability. Also check out the Hankook Dynapro ATM. Staying with an AT tire will get you better siping. Stay with the stock size tires also if you are wanting to fit chains on the truck.
