I did some google-fu and now know what you're talking about. Tires last a long time because you are more often using them on dirt. If you use them on sticky tarmac, maybe not so much, but you can obviously just get thicker tires, and rubber is relatively cheap.
It makes sense for a self-propelled, slow-moving (relatively) lifter with high load factors to use such a system, but as a trailer, the design absolutely blows.
I don't know about the drivetrain they use. I can see some possible designs having significant benefits and major weaknesses. Now you've booked my weekend free time...
actually, I used them for 7 years of asphalt paving, mostly on pavement. We had t change the tires ONCE in the 7 years I was there, despite being run almost daily, 8-12 hours a day.,
The drive train is really not too dissimilar to what is used in tanks, on basic principal.
Also I believe we've already determined it's not a trailer, but a multi use base chassis for commercial vehicles like cargo loaders, lifts, cranes, etc.
