I had to replace all (4) of my tires last week. Had a screw in the center of a tire and brought it to the local Goodyear shop (much more convenient than going to Ford). The sidewall blew out when they were unmounting the tire (no, it was never driven at low pressure). A few weeks earlier, I glanced a curb and both right side tires developed side wall bulges, so they were replaced with the OEM Pirellis. Tried pushing the warranty angle, Ford said "nyet". I said screw this and went with a set of Goodyear asymmetric summer times with a much thicker sidewall. The car has less than 10K miles. I had Pirellis on my 2007 GT and never encountered an issue. Rant over. Flame away.
