the vx and the snow

[Ldub]

on top of that the things that make a good snow vehicle a GREAT snow vehicle are
-A majority of the weight over the drive wheels
-4WD or AWD
-Limited Slip Differentials
-Good Ground clearance
-ABS

The VX hits on all of those marks save the LSD part, the front and rear diffs are open but the "center diff" is essentially the torque on demand which acts like a center LSD... so it gets half a check mark there.

Bridgestone Blizzaks and Nokian Hakkapelittas are the best snow tires money can buy.

I've got a set of Nitto Terra Grapplers on my VX, like I said I haven't snowed it yet, but my friend at the tire shop said they do quite well in the snow, well enough he knows a few guys with plow trucks who run them

Mmmmmm...not exactly, the VX came stock from the factory with a limited slip rear differential (LSD). If yours is "open" something must have been changed before you got it, or your clutch packs may be toast...
I agree with your choice of snow tires, & would add Bridgestone Dueler A/T "REVO's" to the list...great snow tire...

I use my Terra Grapplers for winter tires & they've worked very well.
