Tires look brand new, but are 11 years old. Keep or discard?

This spring I had a trailer blowout while transporting my tractor. Replaced the tire with the spare. Next time out...another tire blew. By then I was really paranoid. Both times I left the trailer and tractor where I was bush hogging until I got another spare to go on the trailer to bring things home. I go no where without a spare. Those tires were around 7 years old and I replaced the remaining ones with new tires. I know better now.

I don't remember ever buying a Michelin tire...however, my Mom bought a new SUV in late 2011 with them on it. She went to the dealership in 2019 to get her oil changed and they said She should replace her tires because they were showing signs of surface cracking. The car had less than 12k miles on it and Mom called Michelin and they told Her to take it to a particular tire shop to get checked. They replaced all five tires at no cost. Michelin paid the bill...
Maybe they are getting better, maybe not.

Same with Bridgestone… very low mileage only to grocery once a week.

I mentioned to my then 88 year old neighbor his tires were all cracked… only 6,000 miles…

Dealer said let’s make a call… Bridgestone furnished 4 new tires to replace the 8 almost 9 year old tires and neighbor paid mount and balance.

I drove for a company for a while back when I was younger... (59 lol) We were dedicated to Bridgestone Tires and serviced the warehouse here in Jax. That building, if you walk around the perimeter is a mile hike! Almost all of our loads were driver unload, and I have "fingerprinted" more tires than most people will buy in their lifetime! (Considering about 1200 tires per trailer, once a day for a couple of years). The heat inside a 53' trailer backed up to a dock in the summer in Florida, isn't for someone used to northern climate.
Just unloading tires is an art, the way it is done!

I have 8 truck tires-- size 295/80R22.5 Load range H.

They look brand new, have under 1,000 miles on them, but are 11 years old. They have been mounted on a truck that has been rarely used, stored indoors, and only occasionally driven. People are telling me to throw the tires away and replace them. A new set, including installation, is close to $10,000.

Q- are they safe to use? Should I replace them and be "better safe than sorry?" Does indoor storage make a difference in the recommendation to replace every 6-10 years regardless of mileage?

Other than discarding, is there any good use for these "like new" tires I would be removing?

Indoor storage makes a HUGE difference on tire life, blazing sun is a tire killer. I would not put 11 year old tires on the interstate at 70mph for a hundred miles, but shorter, lower speed trips wouldn't bother me, especially with that low of mileage on them. JMHO

I wonder if the use of TPMS on all new vehicles will reduce the number of tire failures. Keeping tires at the proper inflation is paramount if you want long life out of them.
