During the transition between the Neolithic and the Bronze Age, the very earliest wheels were made of wood, with a hole in the core for the axle. Broadly speaking, all these early wheels were compression wheels with radial spokes. A large number of experiments and tests were then described, and these went to show the great advantage of a wheel's having a flexible rimâan advantage possessed only by the tangent-spoke type of wire wheel.
