DOT Tire Codes
I'm trying to determine the age of my tires.
I searched the threads as well as the internet and found some basic information on tire dates but nothing that resembled the markings on my tires.
The fronts read: DOT M6AW DBDR
and the rears: DOT M6XD DBDR
Can anyone translate? Thanks and Merry Christmas.

You need the four numbers after the last set of letters in your sequence above.

Go two more circles or bubbles over until you see only a 4 number circle. For instance, the third bubble over on mine says, 1908, meaning 19th week of 2008.

Maybe it's on the inside of the tire?
I just had a set of Firestone wide ovals installed yesterday. I found the tires are on the L. side are not marked either. The ones on the right are 38th week of '09.
These tires are unidirectional, but all 4 have arrows in the correct direction.
Odd?

That's true, it could be on the inside as the DOT requirement is only on one side of the tire and frequently it's the inside. However, I have had another brand (Bridgestone) where they acknowledged there was NONE on the tire at all. No Build Date inside or out. And due to their wear pattern and handling, after much "conversation" they gave me a new set and said don't ask again. Nice huh?

On the asymmetric tires I have seen, the code is on the inside. If the tires can be mounted both directions on the wheel, the code could be on either side. I can see where directional tires could be either, depending on which side of the car they are on.
