What is the maximum permissible wear measured across the diameter of the towing ring of a drawbar?

The maximum permissible wear of the towing ring on a drawbar is specified in German traffic regulations to ensure safe towing practices. The maximum allowable wear that you selected should encapsulate the potential wear limits that maintain the structural integrity and function of the towing equipment.

In this specific case, the answer should include all relevant measurement options. Understanding that some towing rings can have different wear tolerances is crucial; hence the combination of options may reflect different aspects of towing ring wear across various regulations or types of drawbars.

According to German traffic regulations, wear beyond the permissible limits can compromise the safety of the towing connection, potentially leading to failures during transit. Regular inspections and adherence to these wear limits are essential for road safety.
