Steve Mould investigates whether tire balancing beads work by examining the physics of rotating cups, mass distribution, centrifugal force, and wheel hop resonance.
From the video
Answers: Do tire balancing beads actually work?
- tire balancing beads physics
- centrifugal force in rotating frames
- wheel hop resonance in cars
- mass offset and cup rotation
What it concludes
- Tyre balancing beads balance a spinning cup by shifting mass to the position opposite the fixed mass at high speeds.
- Tyre balancing beads only work when tyres reach super-critical self-balancing speeds around 80 km/h or 50 mph.
- Below the super-critical speed threshold, balancing beads migrate to the heavy side of the tyre and make the vibration worse.
