Much better balance solution for this application. They claim to deliver precise balance and they are contained. I have not used them but I've seen a number of credible reviews on them from the motorcycle community.
This still doesn't allow teams to use components beyond their rated capacities. Even with the best balance solution, if the wheel/tire falls apart, they are all dangerous. If the vendor description of the item has a 5000 rpm recommended limit, that should be considered the maximum safe operation condition.

I don't really think its fair to say that its the maximum safe operating condition. Manufacturers often leave a very large margin for error. Its also problematic for components such as the AM pneumatic wheel, which doesn't spec a 'recommended maximum rpm'.
The AM pneumatic wheels were DEFINITELY not designed for operation at, or anywhere close to 5000rpm. Neither are the banebots wheels many have used in their shooters. Nor ANY wheel I've seen in a wheeled shooter, though I would consider MOST shooters currently mounted on robots in their bags 'reasonably safe'. If they haven't blown themselves apart in testing, they likely won't during competition. Could it happen? Sure, there's wear and other things that aren't considered in my extreme oversimplification. I think robots should be designed to contain a failing shooter wheel, but restricting operation of robot parts to manufacturer provided values/use cases is just problematic.
