If it's good dry snow, the VX doesn't even need good tires to take you anywhere you want to go. My Terra Grapplers are almost down to the wear bars and I have no probs going up the steepest roads around here. Last good snow we had I decided to go skiing while it was fresh so it was just me and the snowplows and ski bums out on the road. It was comfortable cruising along at 55 - 60 mph when there were no other vehicles nearby. Then when I got to the steep winding roads in the mountains (don't laugh westerners, that's what they call them around here) with signs saying "chains or 4WD required" - no prob there either - could come to a complete stop on a steep hill and start again without even resorting to the winter button.
The TOD is the shiznit when it comes to forward traction - BUT you have to watch yourself because with two tons of mass and a fairly narrow track width, the VX doesn't have the best lateral grip - so that straight line traction can get you in trouble when it comes time to turn!
Of course when salt and warm temps kicked in there was hell to pay - worn out tires and slush do not play well together...
