8 year old tires and you got 30,000 miles out of them.
You got your money's worth on that set.

Time for new tires!!

 

With no signs of cracking, I would run them. I got 8 years and 176k kilometres out of my Michelin AT tires. I would have gone another summer with them but with towing, I didn’t want to chance it.

 

Run them, but also know that at 8 years old and counting despite low miles on them, internally the rubber molecules can start to break down and degrade. Basic chemistry

I worked at a tire supply factory ( Carlisle tires)as a tire rotator using forklifts. And each batch of tires would get basically a use by date and a don't use and discard date. Anything from auto tires, semi tires to miliary tires including run flats. So I did learn diferent things about tires and that yes infact tires can go bad from the inside. Diferent speeds, different weather,cold and hot temps, tires not being driven on for extended periods of time can all affect a tires lifespan after a certain amount of years.

So just some food for thought.

 

They probably would last, but I still wouldn’t use thise, but you do you. Good luck.

 

Manufacturers don't warrant them for that long.

Get rid of them, they can pop at anytime. Only if the truck was garage kept and away from the sun all these years, I might risk it.

Yes, I have a pile of spare tires with no rot either, some 15 years old, we do burnouts and donuts with them and back in the garage they go.

Running into similar problem with my 3 year old Michelin Defenders. They are 3 years old and beginning to dry rot in this Florida sun. They haven't even hit 40K miles yet.

They'll get replaced next fall.

my dad had a set of those. he didnt put many miles on a year and they started to dry rot while they still had good tread on them. he got a prorated discount on a replacement set

 

If you are just trying to push them a little longer to find a good deal on a set, it’s probably fine (or if you are looking at trading in the truck soon for another). I personally, would not want to keep using them, would avoid highway driving as much as possible on them and would be looking for deals to get new ones.

 

7 years is max for me.....

And I have 4 vehicles that max out before they wear out......7 vehicles if you count trailers.

Something to remember also is that tires these days are not 100% rubber. Not even close. Manufacturers use lots of plastics and other compounds.

 

8 years old, are you a moron? no probably a communist, or worse. Haven't you read and studied about rubber compounds and UV damage? You probably shine em up with armorall 3 times a week too! What is wrong with you, what are you thinking?!!
Ha! you said don't be shy. . . All kidding aside, I'd be wary of highway speeds and start looking for a sale and just get new ones.

 

I had a pickup similar to this. It was garage kept all the time and I probably only put a few thousand miles on a year before I sold it. I figured as long as there wasn't cracking or other damage from sitting in a climate controlled environment, I'd run them.

 

My tires will be 7 years old in March according to the date code. I've only put about 25,000 miles on them and they still look ok except the front oter edges are getting pretty worn. I checked my records and I have had them rotated 3 times since install. Each time was about 6,000 miles inbetween.
I'll probably get new tires at the end of 2025 or 2026. I may go with the Toyo ATIII Open Country in C or P load this time although the BF Goodrich KO2E have been good. Too heavy for what I need though so a little weight savings may help a little in mpg and also outrunning Corvettes...

 

Unless anything has changed, 10 years is the limit for me. That is what I have been told is the shelf life of the rubber.
This includes a brand new tire that has been stored flat lying on a shelf and never installed. .... The rubber starts to deteriorate.

My truck has the 6 ply "extra load" tires good for 75K they are 8 years old and less then 30K on them .... they still look like new and never had a flat.

It is time for me to replace them. My plan is, I have a old truck that needs the same size tires .... A 1949 Dodge. I will only drive that truck local in town for errands.
Top speed on it is 55 mph with a good tail wind.
So my daily driver will get the new tires, the old truck will get hand me downs.

 

Run them.Just dont drive faster than your gaurdian angel can fly

 

For those of you that use DT, I believe after a certain age they won't balance them. Those who employ their services might call to verify.

6 years for Michelin and BFGoodrich (One is a subsidiary of the other)

 

Mine are 2014 with 3/4 of the tread, couple small cracks in tread, run smooth freeway speed, do not get warm. I will run mine until they vibrate or get warm. Mainly plow rig, always park different direction so UV equal on all 4. They were over 200 a pop back then, those Kevlar 10 ply Goodyear Wranglers kept at 60psi. I got my money's worth as well. 77 K20.
Now my 01 GMC Sierra 1500 4x4 I cannot say the same. Just bought needing its 4.8 replaced and 1 tire cracked bad. They must have parked same direction and a UV issue.

 

I’m actually surprised the shop fixed OP’s flat. Must’ve been some mom-and-pop shop as the bigger chains most likely wouldn’t touch such old tires.

 

My Michelin Defenders are 8 years old with 17,000+ miles on them. My truck is parked in the garage all the time so UV damage really isn't a concern. I don't plan to replace them anytime soon unless I have a problem that no one will repair.

This is from Michelin...

 

And when was the last time anyone replaced their spare tire. I personally have never.

 

Some place won’t touch ‘aged tires’. I think the rule of thumb (ROT) is 6 years. I think it’s a liability if they repair and mount the tires. I run mine until the ‘wear bar’. Then I replace them.

 

I replaced my 2017 Silverado tires after 7 years and 50K. There was a big difference in the ride and handling. The outside of the tire might look good. But the internal workings may be tired.

 

Tire Rack suggests anything over 10 years it's time to replace them.

 

Drive them until bald or flat.
Age don't matter.
The condition of the tires does.
See line #1?

Not! Age does matter when it comes to tires.

 

Tires not safe. Integrity broken down after 8 yrs

 

Analogy is same as concrete.
You pour concrete and it continues to get harder every year .... after 100 years it starts to get softer every year until it just crumbles away.

Rubber does the same thing, except I have heard that 10 years is the life span of the rubber, it starts to weaken after that .... same difference, 8 year old tires are reaching the end of their useful life cycle .... time to start thinking about replacements.

For several years I was a Bandag truck tire retreader. ..... First thing you look at is the date code, if the tire is anywhere near 10 years old it is rejected ... does not matter how good it looks.
The tire will simply fail before it runs out the new tread and leave you with a warranty claim replacing the tire. .... And a pissed off customer because when the tire failed it wiped out his fender

 

Only if you absolutely can't afford new ones.

 

I went ahead and ordered new tires today since the outside edges on the front were getting bald and had a little dry rot, Discount Tire wouldn't rotate them.

Ordered 4 new Toyo AT3 265/70/17 115T
The KO2s were E are about 53lbs a piece. The new Toyos will be SL at 39lbs a piece so that should shave about 14 lbs off each corner and make it ride a little softer. I don't really need E rated at all.
