An aerodynamic spare tire cover system for use on a spare tire and wheel combination stored on a vehicle underbody, the system comprising: an annular spare tire cover having a diameter sufficient to cover at least a portion of both the tire and wheel in a spare tire and wheel combination, and defining a central aperture; a removable center cap for selectively covering the central aperture of the annular spare tire cover; a center spacer selectively adjustable between a first position and a different second position with respect to the spare tire cover, where in each position the center spacer is supported by the spare tire cover; and a plurality of removable peripheral spacers supported by the annular spare tire cover, wherein the center spacer, when supported in the first position in the spare tire cover, cooperates with a full sized spare tire to space the spare tire cover a first distance from a first portion of the underbody of the vehicle, and wherein the center spacer, when supported in the second position in the spare tire cover, cooperates with a temporary spare tire to space the spare tire cover a second distance, generally equivalent to the first distance, from the first portion of the underbody of the vehicle.
