The Rugged Ridge Spartacus HD Tire Carrier Wheel Mount is constructed of high - strength powder coated carbon steel to help provide your tailgate with the brawn needed to carry oversized wheeltire combinations. By design , the Spartacus HD Wheel Mount positions the spare high and slanted slightly outward to help maintain optimum clearance from the rear bumper , permitting the mounting of a 35 - inch tire. When paired with the Rugged Ridge Spartacus HD Hinge Casting (11546.61) on TJ models, your tailgate will not only carry the weight, but also maintain easy one - hand access to the cargo area. Each Spartacus HD Tire Carrier Wheel Mount is fitted to work with 5 on 4.5 and 5 on 5.5 - inch bolt patterns and retains the factory high - mount brake light. For a complete Spartacus HD Tire Carrier Kit that includes the hinge casting and the wheel mount, use 11546.60.
