Would you trust 13 year old tires?

I used to run any old pos tire, back 30/40 years ago. Some lasted weeks some lasted longer. I worked as a mechanic and wages were very low,but used tires were FREE!
Well I never had a "blowout", but I had lots of very rapid tire deflations; occasionally at hi-way speed. Either end. Several of 'em. My young wife too.
We're not scared of rapid tire deflations on our DDs.Ok, she might be.
As Time went on,I made better money, and the tires on our fleet were newer, until one day, most were/are less than 3 years old.
The 295s on my Barracudas DD rims tho, are getting on in years. They haven't had traction in something like 5 or 6 years. BFG/Coopers only have a modicum of traction for the first summer, 2 at most. They still get tortured every time the car goes out. Even tho I have a brand new set :) waiting in storage :( . They are probably good for 60fts in the 17 second zone,now;lol.
