an article in Popular Science Monthly, May, 1938 - Rubber Spokes Give Bounce to Airless Safety Tires invented by J. V. Martin of Garden City, N. Y.

Hard wood, embedded in rubber, forms the rim, hoops of hickory incased in rubber and fitted with criss-cross spokes of ribbed rubber. 

A photo of that particular tire clearly shows an interwoven husk of what appears to be metal hoops underlying a heavy rubber tread that is fitted over a standard rubber tire. The underlying rubber tire may or may not be inflated, but regardless of inflation the pneumatic tire hull is supported by the interlocked wire hoops. The wire hoops appear to interlock much like middle-ages chainmail armor.
