A spare tire and wheel assembly is stowed on a rear tail gate of a motor vehicle by a carrier. The carrier is pivoted to rigid vehicle frame structure beneath the rear tail gate for vertical swinging movement about a transverse horizontal axis from a generally upright stowage position downwardly to a rearwardly extending, lower position. A latch mechanism releasably latches the carrier to the tail gate in the stowage position. The tire and wheel assembly is releasably mounted on the carrier.
