I have a 2011 Ford Edge and in the spring the PCM needed to be replaced (covered by warranty). The day it failed, coincidentally, was the day my winter tires were removed and my spring ones put on. My spring tires are the original 18" tires that came with the vehicle and my winter ones (with rims) are 17". Could this difference have caused the PCM to fail (there was no diagnosis on why the PCM failed)?
