"Matthew,
Go Treads was designed for military use in jungle, desert and beach landing situations. It is tough enough to withstand the pounding forces of heavily loaded military trucks and fully loaded semi trucks. This tool works well in sand and mud; that is why the military uses our product.
On the commercial trucking side of things, Go Treads is mostly used in snow because these trucks are not usually on sandy or muddy roads. Since Go Treads folds up to fit in a small area, our customers (military and commercial) like the fact that our tool does not take up much of the valuable cargo space. "
The owner of the company responded to my inquiry with the above, and a video on Vimeo. The video required a password, so I wont share it here. It showed a 10ton Army surplus truck stuck in a considerable amount of sand, and then being unstuck by the product. It has impressed me to the degree of putting four of these on my wishlist!
