Using the generally accepted 0 - 3.2mm or ⅛ inch total toe in you can use this page to convert to degrees as many laser tracking devices require this measurement.

For my car with 24 inch actual tyre diameter it gives 0.15° max per wheel or 0.3° total. Unlike the distance measurement, angle can be used to measure on the solid rim.
