All 4 Continental PRO CONTACT TX tires on 1 week old brand new purchased Ford Bronco Sport VIN [XXX] from Ford Dealer Swelling on Sidewalls in various points. After researching amongst other Bronco Sport Forums issue appears to be common failure on New Bronco Sports equipped with Continental PRO CONTACT TX tires. Requested tires to be changed at Dealer, they found 1 Bronco Sport with Balled up Sidewall issues and wanted to replace "like for like" admitting they have a some sort of FACTORY defect but would not exchange tires for ones with "OUT" Factory Defect. I believe there is Faulty Construction on Sidewall of tire or Like FORD Dealer stated some sort of MANUFACTURER DEFECT. On certain CONTINENTAL PRO CONTACT TX tires from Factory. Symptoms were first noticed 6 days after having possession of new vehicle. And the Swelling appears to be moving TOWARDS the tire TREAD itself. The swelling has become increasingly noticeable and raises concerns about the safety and performance of these tires for my Family Vehicle and others having the same issues. Given the importance of tire integrity for vehicle safety, I believe this issue warrants immediate attention and investigation. I would appreciate it if you could investigate this matter and advise on any necessary actions or precautions that should be taken. Ensuring the safety of consumers is crucial, and I trust that NHTSA will address this issue promptly. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
