What you want isn't really possible. A
tire that is ideal for mud and deep/loose
snow, is going to SUCK on ice. All of the aggressive M/T's I;ve ever seen have a bunch of smooth tread blocks that essentially act as a bunch of
miniature slicks on ice. Yes, that tread design will "dig" very well in mud and/or deep,loose snow (unplowed). They will not work well on ice or hard packed snow (plowed). If you look at tires rated for snow and ice, they have a lot of little grooves in the treadblocks, called "sipes". These sipes create hundreds of "sharp" edges to help the tire bite into the ice.
These tires are a good example of what siping is:

Compare that to the tread design of the BFG M/T KM:

I don't care what "people say", it simply isn't physically possible for that tread design to be anything but
roller skates on ice, even wet/slick roads. The only people saying otherwise must be the ones who
clog up the highway in "bad" weather crawling along at 25mph on an interstate.
Unless you really, truelly, honestly plan on spending the majority of your time driving through
the wilderness, that type of tire is the wrong choice for a street driven vehicle. You will have less traction, and you put a lot more wear and tear on the roads than with a more street friendly ( and safer, better handling tire) tread design.
Now, maybe that Winterforce is a bit too much in the oposite direction, but a good all-season, or an All-Terrain style tread would be a much better choice. While I still don't like the amount of siping on them (or lack thereof), the BFG All-Terrain T/A KO is a decent middle ground.
For a good all-season with good winter traction as well, my preference is the Continental CrossContact LX:
