10. Remove any rust or dirt
from the wheel bolts,
mounting surfaces, and
spare wheel.
{ WARNING:
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 Changing a Flat Tire on
page 6‑85.
11. Place the spare tire on the wheel-mounting
surface.
{ WARNING:
Never use oil or grease on bolts or nuts because
the nuts might come loose. The vehicle's wheel
could fall off, causing a crash.
12. Put the wheel nuts
back on with the
rounded end of the
nuts toward the wheel.
Tighten each nut by
hand until the wheel is
held against the hub.
