I use Blizzaks on my truck in stock size and load range E. I can't imagine anything being better than those. The problem you may have is trying to find some tire that is great at mud AND snow. If you can swing it financially, get dedicated winter tires and dedicated mud tires, that way you never have to compromise. Find a cheap set of take-off wheels and have one set mounted on those. That way, you can swap around when needed. That's what I do. Winter = Blizzaks in 265 size, rest of the year = Nitto DuraGrapplers in 285 size.
