Hi robrob, the point i am trying to make is that AUDI have spent a few hours developing the A4 b8, and cosequently have had to do a bit of testing, the tyres that they sell are AUDI AG Factory approved your insurance company at best is making itself foolish (and in direct conflict with thier parent company Allianz.de) and are WRONG to argue! They are FACTORY APPROVED therefore the most stringent AAnal country in the world (Austria!) accepts that, please ask your dealership for the printout off TÜV Approved fitments for your Model! Your insurance company does not need to be informed that you are driving on them because they are OEM fitment:
