Need help with tire date code
Hello: Just bought a set of 4 Firestone Super Sports tires. I believe that they are vintage, not repro, but I want to be sure.
I have searched the forum and a bit online but I can't find out how to decode the dot codes on the sidewall. The tire code is CYU2 F11617.
Any help in decoding would be appreciated.

I could be wrong but i think your looking at the wrong number/letters.
The age is usually all numbers that can be understood to be a week and a year.
For example mine is 1401 which means the 14th week of 2001.
One tire is 269 which means the 26th week of 1999.
I am torn about getting new ones because they only look a couple years old. I keep it on side streets for the most part as i do test drives but i would never take a trip on the freeway on 9-10 years old.
The numbers I've seen usually have like 2 rubber dots on both sides of the date numbers.
I hope that's what you're looking for.

The tires are F70 15 which I am hoping to put on my 68 L71 roadster for shows. I know that the date code location and format changed over the years, so what works for the 2000's is different than the late 60's early 70's.

I believe DOT/NHTSA began requiring date codes on tires circa 1972. If you can't find the code, they are likely at least that old. Pre-2000 date codes give the numerical week of the year and year of the decade, but you're left to figure out which decade as the year is only indicated by a single digit. In 2000, coding began to include two digits for the year. "Correct" for your year probably wouldn't have any date codes, but if there are extra points for old tires, that's going a bit too far IMHO. Anyway, my opinion doesn't matter and I hope that info helps.

If you can post an image (or link) to the TIN, we can help interpret it for you. Also understand, that due to the date of manufacture those tires are "on the bubble" regarding the date code. Pre-1971 tires may or may not include the TIN. Tire manufacturers were getting ready for the changeover and so tires were produced with TIN.

Also keep in mind that DOT only required that the complete date code be shown on one side of the tire. To make it more difficult to find, many tires have the complete date code (after the "DOT") on the inside of the tire only.

Tire Code CYU2 F11617
Hello,
I have a set of these tires on a corvette I just bought. The tires look great but I don't know how old they are. Were you able to find out any info on them? I'm planning to sell them but need to know what I have before I do. Thanks.
