I'm not a "brainy type" at all but according to how I read the DOT codes found here
http://www.tirerack.com/tires/tiretech/techpage.jsp?techid=11
"2606" would be the 26th week (mid June) of 2006.
The DY code is for the Denham Rubber Corp. Leavittsburg Ohio based upon ths infor I found here.

Yes, I read the date code the same way. I'm guessing that the "K6X" identifies the product (mold), in this case a 7:00 x 17 x 6-ply rated single whitewall. Next time it's convenient I'll take a look at a Lester 6:50 x 17 (1932 Light Eight) or 7:50 x 17 (Twelve), or a blackwall or double-sided white to see if that seems to hold.
