Interesting concept is right......................what I am curious about is what tire wear is like on something like that.
I like the looks of Matt tracks instead

It seems like it'd be good as a toy and that's about it. If you REALLY have to get somewhere that wheels won't take you you use a Pisten Bully or a Muskeg.
A guy up here had them and they did not stand up to any abuse.
The front shaft kept bending/breaking.
Had to keep it under 20mph to make them last any amount of time.
I bet that thing eats tie rod ends like candy.
