Tire problem

July 2020, we purchased 4 cooper tires, size is 225/65 r17 102t. These tires are 80,000-mile tires. Vehicle was taken into discount tire due to heavy vibration when driving on June 13, 2022. The tires had 13,663 miles on them. A tire was found to be separated. Discount tire changed it out with a new tire. On Aug 10, 2022, the vehicle was taken into discount tire again due to heavy vibration in the vehicle while driving. A 2nd tire was found to be separated, and a 3rd tire has a flat spot in it. These tires now have 15,714 miles on them. Again, changed out the separated tire with a new tire. Do not have the dot information on the 2 separated tires. Discount tire disposed of the 2 separated tires each time they serviced the vehicle. The tire with the flat spot is still on the vehicle. There are 2 original tires on my vehicle from the July 2020 purchase. These 2 remaining tires pose potential for a blowout and an accident. Dot number u92y 1cw 4919 & r72y 1cw 2322. I contacted cooper tire, manufacturer, via email 8-16-2022. Received a standard minimal response 8-17-2022. Sent a certified letter 8-17-2022, requesting further assistance. Received another email response stating, "have your dealer inspect the tires and if he determines that the tires failed due to a workmanship or materials condition, he can process the warranty and get the tires replaced. " I will follow this route. Return to the.
