Have you ever been to a speed shop? You need to get your tires balanced
for operation at the expected speed. Harmonics.
Oh, it does! When you're spinning at 60K RPM especially.
You can be perfectly balanced dimensionally (same outline both blades) and
statically (it stays level on the balancer), but until you spin it you
don't know for sure.
