L300 205/60R15 net registered??

Moin! At Ebay Alus I have been covered by my Bulli; the buyer now writes me the following: “Hello, can you call me the Tüv where you got the tires just like that.I was at Mitsubishi, got an expert report with which I have to go to the Tüv.There a single acceptance was made (nothing from the rims in the PC).Fleet!The rolling circumference of the tires is too small.The tacho shows with the tires over 3% more than with the original tires. t:Larger tires (the 65s) or tacho adjustment. tacho adjustment costs approx.150Euro.” So I just went to the TÜV and let the things hammer in and is good, the number with too little circumference I know of my Polo (175/50R13^^) but with the Bulli I hear so`n talk for the first time…. Especially since a factory clearance is available with which one has to drive < not even to the TÜV, but which one only has to carry with the vehicle papers and in case a control of Does anyone have any idea how to help us/him/me??
