2009 Lexus Rx

I was advise by one of the mechanic to change tires immediately. Since my Grand daughter occasionally drive the card, due to safety, We bought 4 set of Brand New Good Year Assurant Outlast Tires immediately (235/55 R18) from Walmart at Farmingdale, NY on 6/12/2023 at 8:00 PM. Walmart stated that they could not put tire on my car for another week so I decided to take tires to my local mechanic who put ALL 4 tires next day in the morning. All tires were installed; however, after driving for about 15 miles, I saw my car pulling. I pulled in safe area and notice that the car was tire was flat. I towed car to the mechanic who installed it. He stated that tire is leaking from side and is NO Good! I went to Walmart to complain about the tire. They punted the problem to call Good Year. I called Good Year at [XXX] to file complain (No [XXX]). Apparently, Good Year tire technician looked in Hurry at the tire and stated that is Road side issue and punted problem again. They stated that they will provide 50% tire cost if we buy again. I believe there is defect in the tire which Good Year (and Walmart) are not owning up to and giving run around. I still have the tire and I want NHTSA to investigate further on root cause esp since I do have 3 other tires installed and my granddaughter is driving. If you have any questions or concerns please call at [XXX] (My Son [XXX]) or me at [XXX] [XXX]. Thank you. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
