Is there a way to trace the age of a tire from it's serial # ?

I have Goodyear Terra Tire 23 x8.50-12
Serial # 8B0K9D9 ( I think)

Thanks

Someone here, had mentioned it a while ago. Can't recall the thread, or who was involved.
I remember they where trying to figure out the age of a GT, and no production dates where available.

Here's how to tell on DOT tires, haven't found anything yet for non-DOT.

Tire Tech Information - Determining the Age of a Tire

Tires Manufactured Before 2000

The Tire Identification Number for tires produced prior to 2000 was based on the assumption that tires would not be in service for ten years. While they were required to provided the same information as today’s tires, the week and year the tire was produced was contained in the last three digits. The 2 digits used to identify the week a tire was manufactured immediately preceded a single digit used to identify the year.


But that doesn't work for your number. I even thought maybe it was hex code, but "9D" is the 157 week... Um... Nope.

Might want to check Goodyear's web site to see if they have any information.

I don't know that there was a way to tell the age from the tire code. But I know this, we can start a log of the tires we know are original to the tractors we have and it it could help narrow it down for the rest of the tires out there.
