radial runout
radial run-out

A bearing with a high degree of radial runout, for example, will produce greater vibration especially at high speeds.

Inner and outer ring radial runout (Kia and Kea) are the measures most often used.

When used to measure radial runout, the stylus is fitted to a large-area paddle that can span the voids in the tread pattern.

Geometric parameters, including radial runout, lateral runout, and sidewall bulge, are measured using a tire uniformity machine at the tire factory at the end of the manufacturing process as a quality check.

Capacitive sensors employ void filtering to remove the effect of the voids between the tread lugs in radial runout measurement, and letter filtering to remove the effect of raised letters and ornamentation on the sidewall.
