Removing the Spare Tire and Tools The equipment you'll need is located in the rear cargo area. You'll also findyour spare tire there. On two-door utility and Suburban models, the spare tire is located at the rear of the vehicle. To remove the spare tire, first open the tire cover, if you have one. Turn the wing nut counterclockwise and take it, and the adapter, off the bolt. Take the tire out of the vehicle and remove the tire cover. On four-door utility models, the spare tire may be stored under the vehicle in an underbody carrier. D c 4-DOOr Utility Models A. Hoist Assembly E. Retainer E Valve Stem, Pointed Down G.
