A bit of mental rithmatic...
10 ton(ne) truck
assume 6 wheels, equally distributing weight => 1.67 tonne/wheel
assume approximately 12"x9" of tyre-ground contact area per wheel (~100sq.in.)
=> 17kg/sq.in or 37psi
(OK, I expect a truck would have lower tyre pressure than that, but I'm feeling generous)
This thing is 3 inches long, and looks to be about 1" across; so with these figures, that's about 51kg that it can support.
In other words; it can just about support a skinny woman stood on it. Or half a decent sized bloke.
Sounds much less impressive than a '10-ton truck'
