Thank you very much for the info. This will be my second winter with the 17" tires and I did notice the speedo off last season. I wanted to reach out and ask before I put the tires on again this season. It seemed such a coincidence that it happened when it did in the spring, I didn't want to cause another failure and therefore be held responsible. Thanks again!! You've set my mind at ease!

Hello all! I'm new to the Forum and I have a question for everyone. 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)? Does anyone know if I have the smaller winter tires on (which does effect my speedometer), does it void any warranties? Any help or ideas out there would be greatly appreciated!
