2012 F150 Calibration

[makamer]

I know this has been asked many times but I have not seen a definitive answer.

I increased the size of my wheels and now my speedometer is off. I tried setting the size in Forscan but then received an error about the BCM not being able to read the data. I would need to do this again to get the exact error. I had to revert back to the original tire size to get the error to clear.

Is there a way to do what I need to get my truck calibrated properly?

anyone? Am I just out of luck?
