Abstract
A non-pneumatic wheel with reinforcement bands that provide structural support for the wheel and a method of manufacture of such a wheel are described. The reinforcement band forms part of an annular reinforcement structure that includes foam spacers positioned between the annular reinforcement band. The foam can be a reticulated foam into which a matrix material such as a polyurethane is introduced. The matrix material can also be used to form one or more features of the non-pneumatic wheel such as spokes, a mounting band, and a hub.
