Personally, I would have replaced them last year.
I have had a perfectly good looking tire give out on year 5. From then on they never see year 5.
I agree with the above. With that much age I don't know if you can really measure your tread depth and go by that.
During a trip out west this summer we probably passed 4 - 6 fivers and TT's pulled over with blown tires. In the last couple of weeks in mild temperatures we have passed two between Illinois and Florida.
It is not worth the aggravation, of the safety considerations to not replace the tires. It is a dangerous thing to be sitting on the shoulder of a busy interstate my friend.
