How old are my Tires? Are they safe?

I woke up this morning thinking about the tires that are on my 1954 3100 5 window. It's mostly original with the 235 engine and 3 on the tree.
recent put new tires on my Mini Cooper Rally car, as I thought they were just getting too old, and I wanted a newer stickier compound. Never thought about the tires on the truck. The tires are the ones that were on the truck when I bought it 3 years back, and while pretty noisy they had plenty of tread, so I did not give it much thought.
I went out the the garage to see if I could tell how old they are. They are Cooper Discovery LT's but I was unable to find any DOT code on any of the Tires. From what I understand, DOT codes have been required on tires since 1971.

Since I can not find a DOT code, are my tires really like 50 years old?

Scary, as some days I do drive it like I stole it. Picture attached of the tire.

If you drive Hiways on a regular basis then replace ASAP.

Did you look on both sides of the tire for the DOT info? They only stamp it on one side...

Thanks Mike B, I had not thought of that. I was able to read code off of 3 of the Tires. None of them good.

(CJL492) (CLJ291)(CUB073) If I am reading it right, the two front tires are from 1992 and 1991, and the rear tire looks like it's from 1973? Really???

I attached the two picts of the ones that were easiest to read.

Crazy. I need to get them replaced for sure.

--- UPDATE ---
I Found a site that suggested if the tire was indeed made before the year 2000, the code is interpreted differently.
So, CLJ-492, was made in the 49th week of the 2nd year of the decade
CLJ-291, was made in the 29th week, of the 1st year of the decade
CUB-073, was made in the 7th week, of the 3rd year of the decade

Regardless, all of the tires are nearly 30 years old. Not bad for getting your money's worth... Ha ha

Code is week and year. So CUB073 should be 7th week of 1993. In any case, they are too old.

I've run (and am running) tires that are 40-50 years old. If they haven't been in direct sun their lifespan is infinitely longer. If there is no visible cracking on the surface, that indicates that the rubber is still pliable. We could argue that tire date coding is one of the biggest scams ever perpetrated on the public, but recent events have superseded that milestone. I go on a tire-by-tire basis - expiration dates are absolutely worst-case scenarios. If there's no cracking I would run them out - but then again I don't believe everything the government tells me and I don't have money to spend replacing tires that I have closely inspected and are still safely viable.

If you want to be safe about it, they're good for tire swings. Just be sure the branch you tie them to is sturdy enough. wink

MiraclePieCo Agree with your take on tires,Ithink they live best in service. To run 80 on the interstate all day better get some Michelins! To get to the gas station in town run beaters have junkers 60 yrs old ,think the warrenty ran out !! My machinery jocky neighbor said keep em out of the sun !!

It seems impossible to wear out old all weather tread; even while using them for donuts and drifting! cool

Might as well treat your truck to some new ones sooner than never.

One other thing to think about is how much smoother your truck will ride with new tires. Those old ones may well not blow out before the tread is worn off, but I do like the feel of new tires after running stiff and noisy old ones.
