Original World War 2 re cap tires industry trade magazine vintage ad for UNITED STATES RUBBER COMPANY of New York City, NY.  There is Still A Rubber Crisis in 1943.  It is true that you no longer need a ration certificate for recaps.  If you wear your tires down too thin so they cannot be recapped, the whole rubber situation could change overnight. Old 1943 dated WW2 wartime era propaganda magazine advertisement.
