New 19" rims/tires affect COMAND GPS?
I just had my new 19" staggered wheels and tires put on my car yesterday. I have the COMAND Navigation System, and I was wondering if the new tire setup will affect my GPS routing. Does anyone know?
I went with recommended 235/35-19 front and 265/30-19 rear...
Thanks

i know a friend with 20's on a e55 and navi that never had problems

Allright, here is some clarification and AMIL, no its not a joke...
The way I understand it from Mercedes-Benz is that the COMAND GPS routing estimates the distances, etc. based on the rolling diameter of the tires.
Now, here are the figures...
STOCK FRONT 225/45-17
Overall Diameter: 24.97"
Radius: 12.48"
Circumference: 78.44"
Revs per Mile: 832.9
CUSTOM FRONT 235/35-19
Overall Diameter: 25.47"
Radius: 12.73"
Circumference: 80.01"
Revs per Mile: 816.6
STOCK REAR 245/40-17
Overall Diameter: 24.71"
Radius: 12.35"
Circumference: 77.62"
Revs per Mile: 841.7
CUSTOM REAR 265/30-19
Overall Diameter: 25.25"
Radius: 12.62"
Circumference: 79.32"
Revs per Mile: 823.7
So in analyzing these numbers, its obvious that the rolling diameters are different for each tire (Front or Rear). So, I am assuming there is some way to re-calibrate COMAND so you dont end up passing your street before the lady shouts "turn next left now."
