I have a 55 Chevy Bel Air in my garage. It hasn't been moved in at least 5 years and has 4 flats. I do have a small air compressor for tires. Guess I'd better get busy! I don't even know if the tires will hold air as the tires are 30 years old.

I think nowadays most if not all tires don't have inner tubes..(remember those?) but are more or less self sealing. I just had a nail removed from one of my tires that was low, and made the mistake of asking how much the inner tube was. The young mechanic just looked at me, confused with his mouth half open. It took an older customer to explain it to him..and me.
