Yes! VelociRAX will clear and mount on a vehicle with rear spare tires (Wranglers, Broncos, etc.). The ability to hinge the rack fully may be hindered by the spare but it will mount to the vehicle. If the spare stops the hinging and the spare can be adjusted upward, the rack will be able to hinge. In general, the vertical post is 13.25 inches back from the hitch pin hole. With our extender/adaptor it allows for 17.25 inches of clearance from the center of your hitch pin hole and will generally allow full hinging to the loading position. If you have more questions on this, please email us.
