To remove an inside-mounted spare tire, reach into your tire's cover and unscrew the wing nut at the center of the wheel. Remove it and the retainer. Unhook the tire from the mounting bracket and remove the cover. To remove a rear-mounted spare tire, first make sure that the carrier arm is fully-latched to the tailgate.

Insert the key and pull the lock case straight off. It is not necessary to turn the key. Put the spare tire near the flat tire. 5-74
