Storing the Spare Tire and Tools 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. The compact spare tire is for temporary use only. Replace the compact spare tire with a full-size tire as soon as you can. See Compact Spare Tire on page 5-79. To properly store the compact spare tire do the following: 1. When you put the compact spare tire back in the trunk, place the protector/guide back in the foam holder. 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. 2. Put the cover back over the compact spare tire and tighten the center nut. 5-78
