Tire Date Code?

[CA.XSer]

Ok I can't find the info for the date a tire was manufactured. I know I saw it somwhere. Can somebody point me in the right direction? Thanks

From another website

"All tires sold in the United States are marked with a DOT code on the sidewall. The last three numbers in this code indicate the date of manufacture. Using 148 as an example, the first two numbers indicate the week in which the tire was made and the last number is the final digit of the year. So 148 indicates a tire made in the 14th week of 1998. (In other words, between 29 March and 4 April.) The year will normally be in the current decade, though if a tire on a used bike looks suspiciously old or deteriorated, it is possible that it will prove to have been manufactured in 1988 instead.

Usually on bikes the code is only 3 letters long or in the case of tires manufactured after 1-1-2000 the code is now 4 letters (at least on Dunlops) so a code of 0200 would be the second week of 2000, or 5101 would be the 51st week of 2001. Car tires also have this code but the numbers are a lot longer and contain more info, in that case you only use the last 3 digits ( or 4 I am not sure how cars handle this).
