Funny someone mentioned trying to get a tire store to air up a tire, but refusing because the tires were too old. Had the same issue with a tire on my trailer, of all things! Boss-man wanted to borrow the trailer for the weekend, and I told him it had a flat. He pulls it up to the shop, and finds one of the valve stems broken. So, he limps it around the corner to the  tire store to get a new stem installed. They refused, stating the tires were too old....even tho they are not weather cracked, or worn out. He wanted me to buy new tires for it, but I dint....not guna spend the $$$$ just so HE could use MY trailer....that's just silly...LOL
Tire dates are important, and if you drive your car, you really need to keep them "fresh", for safety. The tires on my '74 were put on in....1997.....and they're still on it today. No weather checking, plenty of tread left, and they all hold air. I KNOW I need to replace them, but, since I rarely drive the car, I'm just not gunna do it, until time for the next long road trip. Last trip in this car was to C3 Fest/C3VR Gathering at Mike's place....in 2011....on tires that were installed in 1997....perhaps my luck will run out one day, but I'm not going to chance tearing the car up on old tires. I'll take the tires off the Corvette, and put them on the trailer.....problem solved....LOL

When I bought my 69 it had the firestone redline bias tires. I have owned the car for a couple of years. The tires look to be good. They hold air and have good tread. What should I look at to determine their age?  Thanks, Bob

My mistake, I should have read the article first.  I will look to see it my tires have the DOT numbers.  Good article.

That article was pointed at Joel and I.  Mine were installed back in 1996 and at the time a couple of them were already two years old.  (discontinued Goodyear GT+4's)

Oh great!  Rebuild the calipers, fix the wipers (still) and the horn (still) and now a set of tires.  What's that another $1000.

Well, thanks for the info.  I already knew it but was in denial.

Just for information but I found this website advertising Goodyear Eagle GT tires.
They also advertise in the "NCRS Driveline" Magazine.

Haggerty article said: "For example, a serial number ending in 4905 tells you the tires were made during the 49th week of 2005. If there are no recognizable serial numbers, you already have your answer – the tires were made prior to 2000 and need to be replaced."


That statement is misleading at best, and an outright lie at worst.
Tire made BEFORE 2000 also have date codes on them....it has been a standard for many years before the  Gobment got involved. Date codes before 2000 simply do not include a specific serial number....just the date itself. The older coding did not allow for the decade of production because tire manufacturers dint expect tire to be in use that long, so they dint put what decade the tire was made on it, just the last number for the year/
First example(below) is coded for the 51st week of 2007.





Next example is the earlier coding, and shows a build date for the 40th week of the 8th year, but no decade....so it could be from '78, '88, '98.....who knows? Ermm

That article never actually tells us how old those tires were.

I would never pay that much for a 15" tire.

I seen this type of article last year and decided to change my 10 year old tires. I gave the old ones to my brother, still a lot of wear on them. He put them on his truck and 2 of them blew out within 3 months. DON'T TRUST OLD TIRES.

So where is the code supposed to be imprinted?  Inside or Outside?  I can't locate any on the outside of my tires.

You will normally only find the date code info on the inner side of the tire. Depending on if it is a whitewall/white letter, or blackwall, of course. Some manufacturers do put it on both sides. Just gotta look...

Took the wheel off to see what was up with the brakes.  Tire serial # is BEVENX7335.  So I guess my tires are from 1995, 1985 etc.  Its funny, no cracks, no checking and lots of tread left.  Oh well, see my post about brakes too.
