NHTSA Complaint #11561568 — 2018 LINCOLN CONTINENTAL

When rotating tires 12/22/2023, upon removal of the right front tire, it was discovered that the inner sidewall had split open about midway between the tread and the wheel rim, for a distance of about one foot. There was no advance warning of this, and no warnings or messages displayed on the vehicle prior. As this was the first wheel removed, I am not sure what the condition of the other tires may be. As all tires are original equipment to the car, which is 4.5 years old and has approximately 18,000 miles on the odometer, I suspect that all tires will likely need to be replaced as they are all the same date code and DOT number. I have tried to upload pictures, but the webpage doesn't let me.
