Tires: Date code, pirelli p400, dot code

Question
I have Pirelli P400 Touring tires with the DOT code "DOT XM J6 7375.  What is the build date?  They look brand new.  Thanks, Tom

Answer
Tom,

You need to look on the other side of the tire.  What you've posted is missing the date code.  The full DOT code is only required on one side, and it is permissible to have the partial DOT code on the other side.

Here's my web page dealing with this:
