Storing the Spare Tire and Tools
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.
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.
2. Put the cover back over the compact spare tire and
tighten the center nut.
