Rust or dirt on the wheel, or on the parts
to which it is fastened, can make the
wheel nuts become loose after a time.

accident. When you change a wheel,
remove any rust or dirt from the places
where the wheel attaches to the vehicle.
In an emergency, you can 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.
