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, a cloth or a paper
towel can be used; however,
use a scraper or wire brush later
to remove all rust or dirt.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change
or tire rotation to prevent
corrosion or rust build-up.
Do not get grease on the flat
wheel mounting surface or
on the wheel nuts or bolts.
When It Is Time for New
Tires
Factors such as maintenance,
temperatures, driving speeds,
vehicle loading, and road conditions
affect the wear rate of the tires.
Treadwear indicators are one way
to tell when it is time for new tires.
Treadwear indicators appear
when the tires have only 1.6 mm
(1/16 in) or less of tread remaining.
See Tire Inspection on page 10‑62
and Tire Rotation on page 10‑63 for
more information.
The rubber in tires ages over time.
This also applies for the spare tire,
if the vehicle has one, even if it is
never used. Multiple conditions
including temperatures, loading
conditions, and inflation pressure
maintenance affect how fast aging
takes place. Tires will typically
need to be replaced due to wear
before they may need to be
replaced due to age. Consult the tire
manufacturer for more information
on when tires should be replaced.
