2011 4.0 auto 2wd. Seemingly nowhere on the Internet is any resource to help change the tire size on this specific truck. Someone better come in and be an expert in this exact thing or I’m gonna lose my faith in the magic of hobby internet. Some places say it’s in ABS. Some places say it’s PCM but there is no PCM module showing up in Forscan. My only answer lies in figuring out which number in the GEM/SJB module is tire size. Does anyone have any experience doing this? I swear there are only resources and tutorials for new fords and that’s useless for people who have the lobotomized older fords.

Yeah I have a vLinker adapter and the 2 month trial. That does not seem to be the issue.
