FYI Aren Hill IS Vex, he is one of the engineers there. I'm sure he'll provide more data on their testing if you ask.

I apologize, I should have been more clear in my post. I was attempting to say that Aren did indeed say they were tested but did not provide the testing means.

He has now provided the details that were missing.

He was then told "break these" and came back after several hours of driving with the rubber worn off the rollers, no broken tabs.

All it took was to ask him to post more detail (as I did in an email to the address he gave).

I know, I prefer public information to private. Unfortunately, many teams won't go through the process to contact a company to acquire information. Personally, I would love to see the testing processes used on all AM and VEX products on the product webpages.

AndyMark did a great job documenting their tests on their Mecanum wheels, while haven't seen any quantifiable data on the VEX wheels.

I'm curious how the VEX wheels would hold up if they were put through the same tests as the AndyMark wheels.

Do you consider the AndyMark tests in the linked document to be more "real world" than the Vex tests?
