8. Remove all wheel nuts
and remove the
flat tire.
{ 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 6‑90.
9. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.
10. Install the compact spare tire.
{ 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.
11. Put the wheel nuts back on with the rounded end
of the nuts toward the wheel. Turn each nut
clockwise by hand until the wheel is held against
the hub.
