Balancing a Pneumatic wheel

When you couple the strong adhesive and with the centripetal force of the wheel, there's no way these puppies will fly off.

Something to consider is that the way most teams practice is not indicative of an FRC match. Their is significantly more vibration, impact, and otherwise dynamic loading that the robot will see during a match compared to the loads it sees when you drive around picking up frisbees without the full contact of a typical match. Any field reset volunteer could tell you about the buckets of stuff they have to pick up off the field.

I think many people are running tires at 1:1 off a CIM and just assume they are getting close to a no-load free speed. If they were to put a tachometer on it I bet they would find their true rotation rate is significantly slower.
