An extreme off-roading Jeep needs extreme accessories, and the ARIES heavy-duty spare tire carrier for the Jeep Wrangler JK couldn't be more perfect for the job. This HD rear door carrier is designed to be highly adjustable and unbeatably beefy, giving you the freedom to mount oversize spare tires up to 37" in diameter. The Jeep heavy-duty tire carrier is adjustable in two ways. First, the tire mount can be adjusted both vertically and horizontally. The vertical adjustment provides increased clearance for extra-large tires, eliminating bumper interference problems and allowing for up 37" spare tires to be mounted on the carrier. The horizontal function moves the tire mount toward or away from the vehicle, ensuring clearance with the rear door. The second way the HD spare tire carrier is adjustable is in its third brake light bracket. The bracket can be moved up and down as needed. This allows you to maintain safety on and off the road by always keeping the third brake light fully visible, no matter how large the spare tire gets. To give the ARIES spare tire carrier adequate strength to hold large off-road tires, it comes with heavy-duty hinges. These hinges are designed to replace the existing Jeep JK door hinges with a heavier-duty option, strengthening the door and tire carrier for extreme off-roading. The hinges and the carrier itself install with no drilling required, utilizing the existing factory mounting points. The HD Jeep tire carrier is also constructed from welded steel for maximum strength, and it features a highly durable carbide black powder coat finish for superior rust resistance.
