In May 2022, I purchased four Cooper Discoverer A/T All-Season 117T 275/55/R20 tires from Walmart.com for my 2018 GMC Sierra 1500 SLT. In May 2023 my vehicle developed a vibration when driving at certain speeds, so I took it to a GMC dealer for a tire rotation and balance. The mechanic discovered that one of the tires had a large bubble on the inner sidewall. He considered it such a safety risk that he insisted on removing the tire and replacing it with the spare before he would let me drive home. The tire was replaced with another of the same kind and tread depth. Yesterday (September 28 2023) I felt that my truck was wandering and swaying. I made an appointment for it to be inspected on Monday, and planned not to drive it until then. Today I observed that the rear passenger tire appeared low. I was shocked to find a split in the inner sidewall approximately one third of the circumference of the tire. I also found a large bubble on the inner sidewall of the driver's side front tire. I am shaken that I could have had three different tires blow out potentially killing myself and other motorists. I will be retaining the tires for inspection, and photographs have been taken. The manufacturer has been contacted. It seems that other model tires have been recalled by Cooper for the same issue, but I have not found a recall for this specific tire.

All four OEM Bridgestone Dueler A/T P285/45R22 M+S tires are showing premature cracking in sidewall near the bead/wheel. The cracks appear on the full circumference of the tire and vary in length from short to several inches. Depth of cracking is estimated to be 1/16" and growing. The tires, with date code 2318, were on the brand new truck when purchased from the dealership in Aug 2018. The vehicle currently has 16k miles. Both the dealership and local Tires Plus chain have confirmed the issue, but there is not a suitable remedy. Bridgestone will not warranty the tires and replacement under the GM "warranty" is the same price as new aftermarket tires. I believe this is a pending safety concern.
