A preform for fabricating a wheel rim and a method of making a preform is provided. The preform includes a main section and at least one secondary section, each section being formed from composite materials, such as triaxially braided composite material that includes fibers oriented in at least three directions. The main section forms at least part of a lateral section of the preform and the secondary section forms at least part of a radial portion of the preform, the radial portion of the preform being generally perpendicular to the lateral section of the preform. The preform is fabricated from a plurality of composite layers, at least some being custom composite layers having a plurality of axial fibers interwoven intermittently with substantially consistent first and second sets of biased fibers. In some embodiments, the preform is initially fabricated in an intermediate configuration prior to being moved to a final configuration.
