Jolly-John is right. I wouldn't trust these tires to drive around a parking lot. When the tires on my collection get 10 years old, I replace them no matter what they look like. Your tires would probably be good for a trailered show car, but that's as far as I would go. I've seen and heard about too many wrecks with tires that 'looked' good, but were old. They'd be great for a gas station display.
I agree that old RADIAL tires would be a huge liability issue but BIAS PLY tires are a different animal.
There are many 30-40+ year old bias ply tires still giving reliable service on collector cars. The key is to keep the tires out of the sunlight and away from sources of ozone (electric motors).
There was a time when Bonneville racers couldn't get new tires capable of 200+ MPH so they ran 40+ year old bias ply tires designed for those speeds.
The OP has both bias ply and radial tires. The radials would be ok to display on a tire stand. I wouldn't risk putting them on a car, even if it was to be trailered.
