To store a flat or spare tire and tools:
1. Remove the stow bolt extension rod and sleeve
from the jack.
2. Screw the stow bolt extension rod and the sleeve
into the existing spare tire bolt.
3. If your vehicle has aluminum wheels, first remove
the center cap with your hand or the wheel wrench.
4. Place the flat tire face down into the spare tire tub.
5. Re-attach the wheel wrench to the jack.
6. Place the jack into the center of the flat tire, being
careful not to scratch the inside of the wheel.
7. Remove the plastic sleeve from the stow bolt
extension rod. Secure the jack and road wheel
using the larger plastic retainer.
The compact spare tire is for temporary use only.
Replace the compact spare with a full-size tire as soon
as possible.
