What is the correct procedure to adjust radial runout on cast spoke wheels?

The procedure to adjust radial runout on cast spoke wheels involves loosening and retorquing the rim clamps. This is because radial runout refers to the amount of deviation or wobble the wheel has in relation to its centerline when it is rotated.

When you loosen the rim clamps, you allow some movement of the wheel relative to the hub and the tire, which can help in aligning the wheel properly to reduce the radial runout. After adjusting the alignment, retorquing ensures that the rim clamps are securely fastened, which is crucial for maintaining the integrity and performance of the wheel during operation.

Measuring runout while the wheel is on the vehicle provides a context for adjustments since the vehicle's suspension can affect wheel alignment, but the actual adjustment process still necessitates loosening and re-securing the rim clamps to correct any identified runout. Other methods listed, such as rotating the wheel or replacing it entirely, would not address the specific issue of radial runout effectively.
