Greetings gdrill! This BFG tire has separated and can be warranted if the tire is less than 6 years old or within 6 years from date of purchase.
https://www.bfgoodrichtires.com/Tire-Warranty.page
All tires never stop the curing process. The rapid curing happens at the factory under heat and pressure. But afterward, continuing to slow cure with time the tire will stiffen, crack and fail. My belief as a consumer is a 6 year warranty cut-off is kinda/sorta chickenshit. Back in the day, there were no time limits for warranty defects due to tire age. I believe a 10 year old tire on my daily driver would be pushing it unless that tire was once a spare in the trunk. Even then I would monitor that tire for any cracking on a consistent basis once it is on the ground.
Direct sunlight and ozone are the two elements that ages (cures) tires the fastest. Tires in trunks or trash bagged and kept in a cool environment that is away from electric motors or welding will age (cure) extremely slow.
Blocking the weight of the car off tires during long-term storage will remove stresses that encourage separations once the tires are put back into service at a later date.
That puke tire in Kern Dog's photo with all the sidewall bulges is the result of a run-flat condition.

If the tire date code was deciphered correctly, the tire(s) in question are 19 years old.

just because the tire has thread on it doesn't mean its good, and if you live in the south and there baking in hot sun, well reduce life of them
a 10 year old tire that you put 300 hp on gonna bust for sure, it s one thing if your trailering it to car shows or just putsing around town
but if your ripping down the highway you need new rubber every 5 years, if they last that long!

The tires that were on our GTX when we got it were so old, the DOT info was hand stamped into the sidewall! They were coded 1971 !!! Gone the next day...
I should have taken a picture of the stamp, but wanted them off the car.

I didn't save any pictures but I had a bulge on a new Cooper Cobra in the sidewall. Summit sent me a new one and paid for the re-mount and all shipping. Once the tire was off the bulge was due to a lack of belt in the sidewall. It felt just like thick rubber and i could stretch it out by poking my finger in it.
Edit: found them...

I recall the kids that changed out my 27-year-old -new- tires. They looked at me with their -knowing- eyes and smiled at the old man.
My bet is that the -Old new tires- I left with them did not go to scrap.
You can be sure that the kids in those lube joints that change out any tires that are still round have them on their vehicles before heading home that evening.

Ya know, I read that "1999" and thought, "Oh, that's not old." Until you told me. Damn.

49th week of 9. Pre 2000 tires are all 3 digits. Meaning it could be 89. Not sure when date codes started but I think 79 BFGs looked a little different.
2499 would be 24th week of 2099 at this point.
For tires manufactured before the year 2000
The date of manufacture is the last three digits of the code. The first two digits refer to the week within that year. For example, if the last 3 digits are 022, it means that the tire was manufactured in the second week of the year, and the year is the second year of the decade. This is where it gets confusing -- there's no universal identifier that signifies which decade, so in this example the tire could have been manufactured in 1982 or 1992. Some tires do have a small triangle following the DOT code to indicate the 1990s.

It has been about twenty years since BFGs were available with that tread design,that was shown in the first picture in this thread.
