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.
