Abstract
A non-pneumatic wheel includes an outer band, a hub and a plurality of spokes formed from a polyamine material. Each of the plurality of spokes is displaced to create pretension in the radial direction under a design load and the displacement is equal to or greater than the predetermined deflection of the outer band. The plurality of spokes is made from a polyamide material having a conditioned tensile modulus between 600 MPa and 3000 MPa, an equilibrium moisture content of no more than 1.5%, and a fatigue failure resistance that can withstand at least 1 million cycles.
