I also had my tires and rims installed by a dealership. So far I've not had any major problems other than the speedometer re-calibration, which I am going to fix with the X-cal 2. I also have an extended warranty, so if I should have a problem with anything, I can take it right to a Ford dealership with the paperwork and have them fix it. Kinda would seem stupid if Ford wouldn't honor work done by their own people. Ya know?
