Just got a set of Michelin's and the code after DOT is M34N J87X.
I know about the code (e.g. 3411 meaning the 34th week of 2011) and I searched the forums for info and read Wikipedia's tire code info and got no matches. Anyone have the answer?
Thanks in advance and I will call the store if no one here knows.
I don't think thats it. Should be (example) "DOT U2LL LMLR 5111" for 51st week of 2011. The other side of tire should be just the "DOT U2LL".

Longrider, I think what you are looking at is molded into the tire. What you need to look at is BRANDED into the tire after what you are reading. It should be a indented box with numbers melted into that box. What you are looking at tells the manufacturer, location of the plant where it was made, and the size and ply of the tire. This information remains the same but the date the tire was made on changes every week.
The code is not on both sides of the tire, you read the wrong side, Look at the other side of the tire. It should have all those same letters and numbers that you posted but in addition it should have 4 numbers after all of those. And as you stated, the first two numbers wil lbe the week of the year and the last two numbers will be year.

Other numbers and digits are manufacturer specific, and you do not care. Last four numbers are date as you said, but you did not give the numbers, just an example.
