It's the *imperceptible vibration* that causes issues, imperceptible
because modern cars are designed to isolate vehicle occupants from such
things. Because they are *imperceptible* to humans does not mean they do
not exist.


Remember the on the car balancers with the strobe lights?

Only ever used them on large truck wheels a very long time ago. I'm
presuming you mean the type where you have an electric motor with a drum
whereby you spin the wheel up to speed.
The Hunter Tune-in (or it's Alemite clone) was THE balancer for many
years - had them at the first 5 places I worked and I balanced
hundreds of wheels with them. They were OK when they were properly
calibrated but nasty (and expensive) to get calibrated. Had to be 100%
sure the adapter was properly mounted or you'd end up chasingthe
balance across the lot (and sending it out for recalibration)
The "Hoffman" off-car balancer pretty much replaced them - making
them virtually obsolete virtually over-night.(except for the VERY odd
vehicle with drum/axle balance issues)
