Active aerodynamic vehicle underbody spare tire assembly

A vehicle having and active aerodynamic vehicle underbody spare tire assembly, comprising:

• a vehicle having a rearend and a vehicle underbody;
• a snare tire located adjacent to the vehicle underbody, the snare time including a rubber tire mounted on a wheel, with an interior defined between a first outer side of the snare tire and a second outer side of the snare tire, the second outer side is located closer to the vehicle underbody than is the first outer side, and the snare tire has forward portion that is located farther from the rearend than is a rearward portion of the snare tire;
• an actuator connected to the vehicle and to the snare tire, the actuator being electrically actuated to move the spare tire with respect to the vehicle underbody;
• and
• a cover situated over the first outer side of the spare tire and at least part of the interior,
• wherein the actuator is actuated to move the snare time between at least a stowed position and a deployed position, in said deployed position at least the forward portion of the spare tire has a lowered location with respect to the location of the forward portion in said stowed position, and wherein actuation of said actuator and movement of the spare tire between said stowed position and said deployed position is based at least upon vehicle speed, at a first vehicle speed the spare tire is located at said stowed position and at a second vehicle speed the spare tire is moved to said deployed position, the first vehicle speed being less than the second vehicle speed.
