If you mounted the wheel on an axle and positioned a runout gauge along the circumference of the rim, as the wheel is rotated 360 the deflection of the gauge can not be more than 0.3mm.

Likewise, if you mount the wheel on a calibrated axle (one that has the mounting plate exactly 90 to the spin axis, i.e., 0% runout) and position a runout gauge at the outer edge of the rim, the gauge can not deflect more than a specific amount else the wheel would be considered out of tolerance.
