While the AEV Tire Carrier works with its own bumper, it also works with OE and most aftermarket bumpers. The carrier can carry up to a 40-inch spare, Fuel Caddy, and backcountry tools, including a shovel and Hi-Lift jack. That’s a lot of weight. AEV designed its carrier to go through the bumper and attach to the frame for better load-carrying capacity. The Rubicon X comes with a hole in its bumper for the tire carrier.
