How are you evaluating "less severe?" These weights are sold for auto & motorcycle tire balancing. An automotive tire will rarely see over 1000rpm. Small trailer tires may be as much as double this but no where near 3k-5k rpm. I'm surprised no one is discussing the Dynabeads mentioned in an earlier post. 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.
