Hello, so my old lady has just created the winter scrubs and now I have come to the pondering, because my WR are smaller than my SR. The BC calculates everything possible, but with different dimensions the values are different or from what does the BC calculate the whole values? Same is also with the normal km display!? Thanks lg PS: Does someone know a program, in which one can virtually repaint our dear Omi B, with other rims etc. individualize sometimes? Freeware would be required. Thank you
