How to measure runout of pulley groove? Thanks

Pulley diameter 100 mm thickness 15 mm.
Groove V shape 60 deg. Depth 10 mm

The most common way to measure the run out of a pulley is to use a dial indicator mounted at a fix location relative to the shaft. You can measure either radial run out or axial run out depending on how you set up the gauge.

The specific shape of the pulley does not really effect the method.
