I'm confused why they would be hard to quantify - other wheel manufacturers I've researched readily display that data.
The wheels are probably a more homogeneous design, solid web, no spokes, etc...

Also, they probably are pulling their rating from testing, not from calculations. I'd wager most ratings you see are very conservatively low as well.

Even if you pull a true strength from testing this rating also has to factor in the uninformed user, if a wheel is rated to hold 100 lbs and that's what it sees when the robot is sitting on it, it will break on any sort of impact or drop due to that increased loading. I bet when you buy a colson wheel rated for 100 lbs, it's probably capable of handling spikes to 500+ lbs.
