Tires: Age on my tires, general tires, dot code

Question
My General tires show a code of DOT P566 1UP 30x9.50R15LT 104S.  How old are my tires..?  I just bought them as NEW.

Answer
Tracie,

The DOT code is incomplete.

DOT Codes are 10 to 12 digits long.  The one you supplied my tells me it was made in Mexico, the size is 30X9.50R15LT and a code that I can't decipher - what what's missing is the date code.

Look on the other side.  I'll bet the complete code is there!
