Tire Size Calibration

[steves67]

I searched, but can't seem to get a direct answer...

I have a newly lifted 2008 F250 Diesel ext cab.
Just installed 37's on it.

Is there any solution to calibrate the truck to the 37's ?

Ford dealer says no.. Search here seems to say aftermarket only goes to 35's?

Looks like the Procomp only does 35's as well???

dealer can only program to a tire size that is offered in the ford truck line...

did you look into superlifts tru-speed?....

Ya, Looked at it..But their application guide says they only work through 2005 on the F250....So It appears that won't work?
