skidoogal - don't forget that M/T tires aren't the best to use in winter, even on a 4x4 as you can easily get into more trouble than with a similar all-season tire.
To help you out, buya set of M/Ts at a decent price. Dunlop has a nice set that was just released their Maxx Traction M/T tire. It's on their website. Dunlop's M/T's are also siped from the factory, which allows more flex and thus, more grip in wintry conditions. You can get a standard M/T tire siped at more tire places for about $15-20/tire.
