Profile and Diameter Testing of Used Tires with 2D/3D Profile Sensors
Used car tires on fleet vehicles are often in good condition so that they can continue to be used. To precisely determine the tread depth, diameter and radius of these tires, special test systems are used with 2D/3D profile sensors installed on the sides and overhead. During rotation, the tires and their tread are measured with micrometer accuracy by laser triangulation. If the tires still have a sufficient tread depth, they can continue to be used. If the tread has worn down too much, they are recycled. Large quantities of tires can be checked thanks to the high measuring rate.
