Not sure how (if at all) it's used by the speedo/instruments though.
I was told many moons ago that the yaw and other direction sensors are also used on a D2 (RNS-C and RNS-D), but I'm not sure that's true...
I've never bothered changing it (though I have checked it's sensible) for different wheels/tyres, e.g. summer/winter as the diameter (and hence circumference) is pretty similar.

Thanks for the info HP.
Seeing as there's nowhere else in VCDS (on the D3), to sort out wheel settings, I'll give Matty's Nav module adaption a go.
I'll be back.
