Never use oil or grease on studs or nuts. If
you do, the nuts might come loose. Your wheel
could fall off, causing a serious accident.
8. Place the compact spare tire on the wheel-mounting
surface.
9. Then reinstall the
wheel nuts with the
rounded end of
the nuts toward the
wheel.
10. Lower the vehicle by turning the wheel wrench
counterclockwise. Lower the jack completely.
Make sure each wheel bolt is centered in each wheel
hole while tightening the nuts. Tighten each nut by hand
until the wheel is held against
the hub.
