NHTSA Complaint #11541366 — 2011 LINCOLN MKZ

The tire is a NEXEN 225/45R18 After driving at highway speed on an out-of-town trip for several hours, got off the highway on the way to the hotel using suburban roads. About a mile later, a noise suddenly started at the driver's side front. The "slapping noise" got worse as the car went faster. I pulled off into a parking lot and found a steel bead from the tire had come loose and was hitting the inside fender well. I also noticed there were cracks in the side wall. I changed the tire using the spare tire and drove to the hotel. The next day, I went to a local tire dealer to buy replacement tires. Since the car is an All Wheel Drive vehicle, I had to replace all four tires. And, it is a good thing I did since when I inspected the old tires, the other front tire (the passenger side) had side wall cracks worse than the driver's side tire that had the bead separation. The two rear tires showed no evident side wall cracks. I kept the two front tires with the failures and one of the rear tires that did not have any evident cracks. There was not enough room in the car to bring all four tires back home. Attached are photographs of the two failed tires. NOTE: I am a former Director of the Office of Defects Investigation [XXX] ) and this is my wife's car. I brought the tires back with me since I believe ODI may want to have the tires in the event it believes a PE is appropriate. The tires are in my garage in Northern Virginia. The email and phone number are mine, not my wife's. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
