    Tyre size

    What tyres would need to go on some RS4 17's to keep the same/similar rolling circumference as my 16's?

    im thinking 205/45/R17?

    225/45 is standard fit on TQS and S4's, and is the same diameter as the 205/55r16 tyres fitted to the 16's from factory.

    Can you correct the % speed differences with in VCDS?

    I've noticed on newer cars you tell the speedo if you're running winter tyres or not, so I assume this corrects the speedo for different size tyres.

    The speedo is out by more than 0.3% from the factory so why worry?!

    You should have 205/55r16 at the moment, so you want 225/45r17 if you are going with 17's (same size as b5 S4 & 1.8tqs)
