Looks very cool, but expensive!  No need down here with our .5'' yearly average!

Definitely cool. I saw something similar but it was as a replacement for your wheels instead of a drive on style. I imagine people who use snowmobiles or chains pretty often would like them.

I wonder how much extra stress that rig puts on the steering components of a front end.  It certainly will take a lot more force to change the angle of the front treads than it does to change the angle of a wheel for steering. 

 

The contact patch of a tire is in line with the "kingpin" inclination.  Yes, I know most pickups no longer have kingpins, but the term is still used.  It's the line that runs between the upper and lower ball joints.  Those treads are at least four feet long.  That means there is a two foot lever on each side of the pivot point, where a tire only has a few inches of leverage.

I thought about that too but I would bet it doesn't add to much additional stress since the snow is slippery to an extent. Now on dry pavement I bet things would start exploding pretty quickly.

There's a cool video on you tube of a 1920-1930 truck driving on tpo of the snow using what I would describe as belt drive auger drums for propulsion. I can't seem to find it.
