In most cases, rims that have not been type-approved by the car manufacturer together with the vehicle or VSA/ASA-approved by an importer must be inspected separately. A simple rim report such as the one we issue is required.
A report from the DTC or FAKT allows changes to be made to the vehicle that deviate from the legal standards. For example, if the offset of the opposing rims is reduced by more than 1% of the track width, this results in a track widening with a deviation of more than 2%. In this case, you must present a rim report and a test report from the DTC or Fakt for the track widening in accordance with VTS Art. 56 Para. 1 + 3 when the vehicle is inspected (at the cantonal road traffic office).
