Dennis et.al.,
Are you sure these are sill in production? The only review I saw was from 2000. The only difference I saw was a softer compound. For Ice, I would want siping.
If you look here:

they don't even list a price. If you are really interested in these, you might want to call BFG tomorrow. This sounds like a red herring.
This article implies that no such beast exists:

"BFG’s engineers told us that the new Mud-Terrain T/A KM offers the same, or better, traction in the rocks when compared to the now defunct Radial Mud-Terrain T/A Moab Edition tire. We drool over the traction possibilities of a Mud-Terrain T/A KM Moab Edition, but alas, we were informed that this idea isn’t in the works at this time."
