My Limited is coming with a full size spare due to the trailer tow group. One dealer explained it as "Jeep doesn't want you without one when you are towing, that's why the full sized comes with the tow group"
Every Cherokee I looked at had a spare, quite honestly, I really liked the storage compartments that come with the compact spare, but I'll take a full size for when I need it any day....
