One "convenience spare" that I pulled out of a 2000 Chevy Astrovan that had 14" wheels before I junked it. The steel wheel is rusty after being under the van for 20+ years, but the Goodyear tire rubber is perfect and still has air pressure in it and I have never added air to it ever.
Probably will fit many vehicles, but you will have to do some research to see if it will fit on your vehicle (or we can try a test fit when you come to look at it).
