yellowblue Storing the Flat Tire and Tools CAUTION: Storing a jack, a tire or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place. After you've put the compact spare tire on your vehicle you'll need to store the flat tire in your trunk. Use the following procedure to secure the flat tire in the trunk. Put the flat tire in the trunk so the side that faces out when it is on the vehicle is facing down. The full-size tire will not fit down into the well. Place it so the front is in the well and the rear is out of the well. Put the bolt through one of the wheel nut holes, install the retainer over the bolt, then install the wing nut. Put the spacer and nut next to the tire in the well. Store the cover as far forward as possible. The compact spare is for temporary use only. Replace the compact spare tire with a full-size tire as soon as you can. See "Compact Spare" in the Index. See the storage instructions label to replace your compact spare into your trunk properly. When you install the wheel cover on the full size tire, tighten the nut caps to 5 lb-ft (7 N·m). 5-32
