Having been here myself and helping marv obtain 4 brand spanking new tyres courtesy of Audi, I agree that in the event you have an accident and the investigators take your car away to check it over, I am almost certain that your car being fitted with tyres different from the manufacturers specifications would give the insurance company sufficient grounds to not pay out - using the assumption that had the correct tyres been fitted, the accident wouldnt of happended!marv wrote: I doubt it would come to it, but there is a small chance that insurance may be invalidated if you had an accident and the recommended tyres were not fitted.
If Audi specify that your car requires XL tyres, it must be for a reason. My 2005 states they must be XL. Is it worth the risk?
