When It’s Time for New Tires
-
Rust or dirt on
a
wheel, or on the parts
to
which
it
is
fastened, can make wheel nuts become loose
after
a
time. The wheel could come
off
and cause
an accident. When you change a wheel, remove
any rust or
dirt
from 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
you
need to, to get all the rust or dirt
off.
(See
“Changing a
Flat
Tire” in the Index.)
One way to tell when it’s
time for new tires is to
check the treadwear
indicators, which will
appear when your tires have
only
1/16
inch

mm)

less of tread remaining.

need a new tire if any of the following statements
