Sorry it took so long for you to get any sort of reply 
but you did ask a valid question.
Many people here will say that if a tire is more than 5-6 years old, it may be a good idea to toss them. If there is visible cracking of the rubber between the tread or on the sidewall, that can indicate dry rot has caused that.
At that point, it certainly would not be a good idea (much less safe) to use the tires at anything such as freeway speeds or high speed use such as track days. The tire's plies could separate, causing the tire to come apart with no warning.
Sure, tires can be expensive to replace, but given the potential for a disaster, you do have to think about what can happen....

That's pretty much what the gentleman at the tire store explained.
I probably shouldn't have deleted my original post, but I found my own answers, so ...
I confess I was looking for a fast response, and my penalty was two days of research.
Btw, I bought Michelins.

Replace them
Many manufacturers recommend not installing tires over 5 yrs old, even if new stock. Much like a rubber band sitting in your desk drawer, the rubber ages and loses its stretch properties. splits and then snaps.
I recently replaced a set of "like new" Goodyears on a set of 1993 wheels that had date codes of 1002 (Week 10 of 2002). I had them on the car for a short period of time and the traction was terrible as the compound had hardened. When taking them to be changed in my truck bed, the easily slide in and out of the bed. New BF Goodrichs stick like glue, but my drive time has been very limited (update NY it's still winter). I could not slide them in the truck bed. Had to lift and drag them.
Techs said they have seen delaminated tires that looks new but were not. Many will not install tires on cars if more than 5 yrs old.
Not worth the risk to life and vehicle.
