NHTSA Complaint #11526271 — 1989 FORD MUSTANG

I have had the outside sidewall separate from the rest of the tire on two occasions, with these tires. The first time was in May of 2021, the second on June 1, 2023. I currently have the tire that separated on June 1st. Both times I was on the highway driving around 70 when the car began to shake violently, as if I was on an exaggerated rumble strip. I was able to pull into the emergency lane and change to a spare. The first time I assumed maybe the tire was low on air and didn't report it, however now after having a second tire do the exact same thing believe they are defective. Tire size is 225/55/16, for full disclosure I did purchase the tires and wheels off craigslist, however they were in very good condition. I Believe Granada is a Les Schwab brand. Picture of both tires are attached.
