Just purchased some new Michelin Pilot tires witha date code of 004X, can anybody explain this one? First 2 digits are supposed to be the week, second two the year? Appreciate any input.
This page contains a complete list of all tire plant codes. The list is sortable and searchable. This data was originally hosted by the Tire Safety Group.

According to above DD11 is "manufacturing code" and it is probably Michelin proprietary number.
As soon as you post picture with date code we can tell which week of the which year it was made.
