8. Remove all of the wheel nuts
and place them in a dry, clean
place to avoid getting dirt in the
threads.
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, use a cloth or a
paper towel to do this; but be sure
to use a scraper or wire brush
later, if needed, to get all the rust
or dirt off. See
.
9. Remove any rust or dirt from the
wheel bolts, mounting surfaces
and spare wheel.
10. Place the compact spare tire
on the wheel-mounting surface.
