has anyone had any luck getting the BCM, TCM, PCM to recognize a larger tire without throwing tire/axle codes?
I have tried re-learning the PCM that did nothing. Unfortunately in the latest version I am unable to re-learn the TCM.

I have a '17 Superduty. I used the tire change mod listed on the spread sheet. I think there was a max size of ???(less then 35", I can't remember), sorry been a couple months since I did it. I'm now running 325/60/20 and before I made the change my speedo was out a good 10%, now its less the 5%.

Anyone figure out a solution to this for tires larger than the max? I tried running the TCM Initialization/relearn vehicle data and it fails to run every time saying “the procedure has been interrupted.
Please help
