NHTSA Complaint #11666161 — 2005 CHEVROLET SILVERADO 2500

I bought tires from Walmart.com website in July 15 2023 and had them installed on a 2005 Chevrolet 2500 HD pickup. This was at the Walmart Laramie store. Between that time and Fall of 2024 one of the tires had a flat and Walmart Laramie, Wy replaced it. On October 7 2024 going to Riverton, Wy. the right rear passenger tire had a blow out. This was on I-80 going west towards Rawlins. It scared the beejeezus out of my young grandchildren. Four hours later, it was replaced with the spare (I did not have a jack in the vehicle and called a tow company). I took the tire to Walmart Riverton and they told me in the tire center that the tire was too badly damaged. They wondered where I had bought the tires. I told them in Laramie at Walmart. They looked me up online and found the tires. They told me they could not replace the tire although it was under warranty. The problem was that they are car tires and not light truck tires!!! They told me to call up Laramie Walmart and the tire manager would take care of me. I went home and did so. Jackson the tire manager said he wasn't going to replace them and that it was all my fault and that I forced them to put those tires on! He lied to me about what happened with the tires and them installing them. I went back to Riverton Walmart and again talked to the tire manager (Tyrone). He said that he would talk to the store Manager and they would make it right. He said he would order the correct ones, install them and then charge the Laramie store. I'm not driving the vehicle anywhere. What can I do about it? I know nothing about tires and have never been a tire company employee. This has been going on for months. Last week the Riverton store said they could mount and balance tires for free but I would have to seek a refund from the Laramie store to reimburse me after I buy new tires for $1200. I live on Social Security of $1229 a month!! 2 of 4 tires have failed and I don't have anywhere near the 60,000 miles warranty Can you help us?
