Bead to Bead contour measurement can be a valuable testing tool in many areas of tire tests. Endurance testing as well as tire research can benefit from the knowledge gained through non-destructive, contactless tire tests using bead-to-bead sheet-of-light sensors. The quality criteria used by tire manufacturers were defined when single track geometry measurement systems were prevalent in tire manufacturing. With the advent of sheet-of-light systems it is necessary to consider adapting these criteria to ensure more precise fault evaluation compared to single point systems and take advantage of the additional data provided by a sheet-of-light system.
