An extremely rare item, the AMC / Chrysler OEM spare tire carrier was an option on early 90s era Cherokee XJ models. There were 2 main types of tire carriers, and for the purpose of this post we will focus on the bumper-mounted tire carrier. These tire carriers were only offered on earlier model Cherokees, pre-97. So, if you have a 97-01 model, this requires you to drill into your bumper, mount the catch on your hatch and use a license plate relocation kit, like this one from Quadratec.
Here are some pictures of how it looked like from the factory, as well as some parts diagrams and some example installations. Thanks to user DarrellXJ for the pictures on CherokeeForum.com.
