Transfer case coding on E70

[KristjanL]

3km/h is quite a lot of difference when driving straight. Xdrive systems are very sensitive to different tire sizes. Your tire sizes seem to be correct, if i remember correctly. These sizes should also be listed on the sticker in the drivers door opening. But different brand/model tires are not the same. You can take 2 different tires with the same size markings and they can be quite different in actual size. I would find a set of 4 wheels and test drive with them.
