What makes a good mud tire is sort of the opposite of what makes a good winter tire. And like Matty said, don't go too wide for a winter tire.
I've got a set of Cooper Discoverer S/T for my truck. I went slightly oversize with a 31x10.5R15, which is pretty common for Jeeps. At that size they are referred to as a "flotation" tire, which they really are. Fantastic on mud and loose snow, and pretty much everything else -- *except* black ice or regular ice. Then they get pretty spooky.
Yet the exact same model of tire on my Chev 1/2 ton work truck was just fine in winter. I think the main difference was that the Chev is much more heavily loaded so the weight/tire footprint ratio was better matched. The Ranger is a much lighter vehicle, so for winter tires you'd really need to cut down on footprint size to avoid becoming an unguided tobaggan.
I just use the stock Goodyears, which I got siped, in the winter. Better than nothing for now. When they go, I'll get some Blizzaks or something.
If Princess Auto were a real girl, I'd ask her to marry me.
