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. When storing a full-size tire, use the extension and protector/guide located in the foam holder to help prevent wheel surface damage. To store a full-size tire do the following: 1. Place the tire in the trunk, valve stem facing down with the protector/guide through a wheel bolt hole. 2. Remove the protector/guide and attach the retainer securely. The cover will not fit over a full-size tire, so be sure to store the cover as far forward as possible. 5-91
