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

[mdicken1]

My wife recently went thru cancer treatment and a transplant which required us to drive from our farm almost 100 miles one way to a major city in the south. Her 4Runner had really nice Toyo tires with lots of tread left, but they were 7 years old and since interstate traffic typically runs at 80 MPH with high temps on the roadway I did not want to take a chance of a blowout so I put a new set on. Interestingly, our daughter has our older 4Runner and she was running our last set which was about the same age and she had a blowout on the interstate. My home rule is old tires, old car batteries, and old water heaters need to be replaced before they let you down at the worst possible time.

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?

I got this off the web, but it is consistent with what I've heard all my life.
Tires should generally be replaced after 6 years of use, with a maximum life of 10 years from the date of manufacture, regardless of tread depth. Rubber degrades over time due to factors like sun and oxygen, leading to cracks and potential blowouts, even on unused tires. To find your tires' manufacture date, check the DOT code on the sidewall.

If you blow a tire due to age, how much damage is it going to do to the vehicle that it is mounted on?
If you blow a tire due to age, how much is it going to inconvenience you? Are you capable of changing the tire on the side of the road? Are all the drivers of that vehicle capable of changing the tire?
If you blow a tire and it doesn't destroy the fender, lights, etc...how much is it going to cost to have a road service come out and change the tire? What is that replacement tire going to cost you if you don't have a spare, or if the spare got used previously on the same trip?
I moved a "stolen" 5th wheel camper for a co-worker of a good friend, from south Florida to my house and then over to the panhandle of Florida. Checked and aired up all tires, made it 100 miles before one blew. He called a road service, which was expensive. Made it another 50 miles and blew another. I called him, suggested my brother come down, remove the 3 tires, take them to a shop and replace those 3, then remount. He didn't want to, but finally agreed. Unbeknown to me, he thought I was "padding" the costs and making a bunch of money off him. (Which is strange since he called the first road service and paid them). I got the trailer to the destination, got paid and forgot about it. Six months later I got a call from him, apologizing for something I wasn't even aware of. He had the trailer moved again, and it cost him almost $400 for a short distance and they blew a tire. (failed to check tire pressures before departing) The road service cost him almost triple what he he paid my brother for coming to help me and that road service didn't travel even a third of the distance my brother did.
Basically, when you blow a tire on the road, you are at the mercy of whomever you call and there aren't that many road service people if you don't include the ones that you join beforehand.

Wondering if deformity from sitting around a lot creates weakened areas in tires. Keeping tires aired up would be a good idea.

For my wife's 2017 Escape new tires and battery at 5 years. I don't follow those rules for my 2 trucks ( 1995 Ram battery from 2015) but got to make sure she gets home when out by herself. Married 49 years next March. Obviously she is a keeper

I once bought a new 4WD vehicle that had been stored outside for, by coincidence, 11 years as a result of customs impounding. This was in the Middle East so not great conditions for tyres. I was advised to replace the tyres (essentially all brand new) but put it off as they looked fine to me. However, when my son (always a speedy driver) had a full blowout on the motorway and barely managed to control the vehicle, I promptly changed all the tyres.
Lesson learnt. Old 'new' tyres in a hot climate are a death trap.

We would certainly use them. Not being in the sun should help. Just keep an eye on them for any cracking when driven.
By the way, we just spoke to a tire man and he said after 10 years the rubber gets old, not 6.

It depends on many factors, sun will kill tires over time but, you say they have been indoors. I pushed the ten year thing on my motorhome and ended up buying tires in Arkansas when they started flying apart one by one. If you're just doing short trips close to home you might be okay. In my case they looked good until they failed.

I guess the tire man you spoke to knows more than Michelin? Their tire recommendation starts at 6 and ends at 10 given the conditions the tires are kept in. Your statement gives the impression that they are good until they reach 10, which could possibly happen, but not in Florida!

31 years and counting on these Mickey Thompson tires. These were put on in either 1993 or 1994. I think they have less than 5,000 miles on them. I finally knocked the dust of the jeep this year after sitting for the last 3. Took it by the tire shop for a slow leak and we took a look at the inside of them while broken down for any signs of deterioration or cracks. Still look like new inside and out. I don't have a top for it though so it has never been stored outside.
