Abstract

A vehicle tire assembly having a plurality of flexible spoke portions that extend from an outer annular ring to and inner annular ring. Adjacent pairs of the flexible spoke portions define a plurality of gaps therebetween. A plurality of electro-active members, are disposed radially inward from the outer annular ring and radially outward of the inner ring. The plurality of electro-active members are configured such that in the absence of an electric current flowing therethrough, the plurality of electro-active members flex in response to flexing of the plurality of flexible spoke portions. In the presence of an electric current flowing through the plurality of electro-active members, the plurality of electro-active members become more rigid and less flexible adding corresponding stiffness to the plurality of flexible spoke portions.
