I have a 2014 A5 Coupe Quattro. 2.0 TFSI base model. My speedometer over reads as 130 Kph is an actual 126 Kph. I think I see the problem. They specced the bigger wheels on the S-Line and they are probably more like accurate? Can anyone confirm this as I am now looking for some 19" wheels to run summer tires on.

So I replaed my 40 aspect ratio tires with 45s. That brought my speed to bang on accurate.
