The "spare tire" was invented in 1904. I think Ducksface's memory may be influenced by the U.S. government prohibited spare tires on new cars in 1941. Shortages of resources caused by World War II led to quotas and laws designed to force conservation, including rubber that was produced overseas and difficult to get. A similar ban was also implemented by the U.S. during the Korean War in 1951.
