NHTSA Complaint #11469724 — 2001 CHEVROLET TAHOE

I bought Achilles desert hawk uhp 285/50/R20 tires in late 2019 from Walmart . and had them mounted in 2020 from discount tire. Within 10 months of tires being mounted I had a vibration and it was getting worse every day so I started looking at it and found I had a separated tire on the driver's side front. I put my spare on and contacted Walmart which told me sorry for your luck and there is nothing they can or will do.so I contacted discount and they said to contact Achilles tire. I did and never heard back from them. I then forgot about it until roughly 5 months ago when passenger tire was separated. Then 3 days ago the passanger rear separated and now today the driver's rear has separated. I understand 1 tire possibly 2, but to have all 4 tires separate in less than 2 years and in under 10,000 miles is mind blowing to me..I have all the tires and I filed a complaint with Walmart and Achilles after the 2nd one. I honestly don't think it's discount tires responsibly. I only had them install tires because walmart would make excuse after excuse and I got fed up with it. There should be some sort of liability to the manufacturer and to Walmart. I am asking you if it's possible to look into this. 4 tires separate in 2 years you ée⁷⁷e77⁷e⁷
