Dear forum, that there are 17, 18, 19 and even larger customs data (no, not the charges when crossing the border to the nice gentlemen in blue – partly also in green) for the Phaeton tires, that I have already noticed as a semi-quasi-phaeton technician. In this context, I have come to a question with relaxed Christmas-on-the-couch- lying-in-circle-my-all-loving family mood. If I have wheels with a larger size (larger inch indication) on e.g. one say sometimes 17-inch Phaeton montiere runs then the then faster (same engine encirclement with larger wheel circumference) or.. At the same speed (one Phaeton drives another with 17 inches side by side with 19 inches) the consumption of the Tacho must be adjusted in some way. Only such a overlay from a winterly-deep-scneite-but-comfortably-comfortable house.
