Just bought the wife a 49 Ford Coupe. Guy we bought it from says the tires are new old stock from the sixties. He put tubes in them and said it would be safe to drive on them. I'm a little concerned about rollin around too much on fifty year old tires. He said when he got them they were still in the original plastic or paper wrapping. They look and feel pliable, but still make me nervous. Anyone have any experience with this?
