after I wanted to have an appointment in the VW car dealership to check my chassis…. background, my Phaeton “rumbles” on a bad distance, and actually passes through every channel cover clearly. I don’t know the behavior of my previous Phaeton. I had pushed that to my winter tires in the last weeks. But…… with the recently installed summer bikes it is the same. And, no, it’s not 19″ but 17″ wheels. Anyway, I have massive doubts about the competence of the car dealership…. Gruss pesbod
