What is the date on the tire? It will typically be a 12 digit code - the last 4 will be the date. For example - 0410 would be 4th week of 2010 is when it was manufactured. If you have records showing all rotations then you may stand a chance of getting some credit towards the next set of tires. They will be looking for rotations every 6k miles and they will be able to tell if proper inflation and alignment was done while the tires were in use.
Why does the date matter? Does the tire rapidy loose integrity with age, and how old is too old. What if they are stored out ot the sun?
I have a lawyer buddy who does tire defense work. He likes Michelin. He sees too many Coopers.
Age is a big deal, more with some than others it seems. I have a set of Goodyear Wrangler RTS that are cracked all through the tread, despite still haveing over 50% tread. Mfg date is 2005. From what I've read, this is typical for that tire.
The other thing is a repair. If you repair with a patch inside--which I always thought was the best way--you leave a channel open for water and debris, including road salt if present, to get to the steel belts. The results look just the pics the op posted, although other things cause that too.
Back to the repair--the patch inside and a plug glued into the hole is the best way.
Anyway, great save on the part of the OP. Even watched, good tread, properly inflated tires can let go. That pothole 15,000 miles ago may have caused a little issue that has grown into a killer.

Sorry to preach but.....
Yes tires go bad. That doesn't mean suddenly 7 years + 1 day
and poof the tire is bad, but a pothole a 2 yr old tire survives can
destroy an older tire.
Of all the places to try to save a buck - safety related items just
ain't the place. $800 for 4 new tires spread out over 5 years is 44 cents per day. You likely spend more on cable/satellite each day.
Maybe buy 2 tires today, and 2 more tires is a couple of months to
spread out the cost.
YOU are responsible for the lives of the family/friends in YOUR care.
Check your spare - it might be much older.
I've seen 10 year old tires on a car kept in the garage - hardly ever
driven by the little old lady next door - less than 14k miles on her car.
Tires had nearly new treads, but the sidewalls were totally
shot they were so brittle they looked like if you kicked them or pushed
too hard with your finger you could put a hole in the sidewall.
Here is a news item from 2005.
In case you don't wish to view it, 2 kids died when a "new"
(6 years old, presumably stored on a store's shelf) tire was purchased
and the tire blew on the hi-way.
Amen! at $1200 for a set of four that's $0.16 per tire per day. We spend more on gas per day with our guzzlers. It's just that gas bleeds our wallets slower than shelling out dinero for new tires.
If you travel 30K miles in the five years, at about 10 mpg, you'll use 3,000 gallons and be spending roughly $5 a day on gas at $3 per gallon.
Quality, well cared for tires are a huge safety gain for our heavy beasts. Buy good tires and take care of them.

I think tires are the most under-rated safety feature. We spend gobs of money for child seats, air bags, halogen lights, etc., but cheap out when it comes to tires. Tire pressure should be monitored as well.
