The present invention provides a unitary run flat tire (RFT) reinforcement using filament material that is formed into a relatively rigid shape. The reinforcement is insertable into a mold for an RFT support and can maintain the needed structural rigidity for such insertion. Further, the invention provides an RFT support that is molded and includes the RFT reinforcement. The invention also provides a wheel assembly including a tire, a rim, and an RFT support between the rim and the tire, where the support includes the RFT reinforcement. The RFT support can have a colored indicator formed or subsequently applied thereto to indicate one or more attributes of the support.
