Age of "new" tires

To me, a couple year old tires on a driver will be worn out before seven years, and I wouldn't worry about it.
I have several cars with timed out tires on them. Until I KNOW I will be putting on a couple thousand miles a year on em, the aren't getting new.
When they do get new tires, they better be NEW, cause I need those seven years.
That's my thinking, but I'm pushing it now. My tires are 20 years old now, Red lines on my Dart. I will not "HOT DOG" it now but will take it out on a Sunday drive. It is kept indoors and I do check for cracks. At $250.00 a tire, I will stretch out the years a little longer. I sure do miss the pounding of the gears. I'm debating on buying a set of "TA's" and installing them on a set of Rally's that I have and saving the dinosaurs for car shows.
