When it comes to determining the age of a tire, it is easy to identify when a tire was manufactured by reading its Tire Identification Number (often referred to as the tire’s serial number). Unlike vehicle identification numbers (VINs) and the serial numbers used on many other consumer goods (which identify one specific item), Tire Identification Numbers are really batch codes that identify the week and year the tire was produced.
The U.S. Department of Transportation (DOT) National Highway Traffic Safety Administration (NHTSA) requires that Tire Identification Numbers be a combination of the letters DOT, followed by ten, eleven or twelve letters and/or numbers that identify the manufacturing location, tire size and manufacturer's code, along with the week and year the tire was manufactured.
Tires Manufactured Since 2000
Since 2000, the week and year the tire was produced has been provided by the last four digits of the Tire Identification Number with the 2 digits being used to identify the week immediately preceding the 2 digits used to identify the year.
Example of a tire manufactured since 2000 with the current Tire Identification Number format:
In the example above:
DOT U2LL LMLR 5107DOT U2LL LMLR 5107Manufactured during the 51st week of the yearDOT U2LL LMLR 5107Manufactured during 2007
I don't think you have found the right numbers. I would suggest that you look for am example like the one shown above.

Froggy,
Are your codes are from slicks? They look similar in format to some I have. That code does not work using the example above. I too have wanted this code. I bought a set of new Continental slicks that were for the previous year of a pro series. One had a small chunk come out, exposing the steel radial. That makes me wonder how old they really are, even unused when I received them. I did not take this up with Hoosier/Continental.

I think they have to look them up to see the date.
Guys do not confuse these with DOT standard codes. They are not those.

I got the info finally after 3 calls, not a huge priority (on their end) I guess, oh well.
All the tires I bought were 1.5 to 2 years old. Hoosier actually considers RACE tires to have a 4 year shelf life, unlike street tires which generally have a 6 year shelf life. Either assumed to have been properly stored.
Race tires have certain preservatives left out to make them work better as race tires.
There is no "code breaker" info that I was made aware of. Each has to be "looked" up by some engineering/manufacturing dude.
So if you buy not DOT tires direct from Hoosier they are going to be in that range. If you buy from another vendor you will have to ask them.
