Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation on page 10 53.
Make certain that all wheel nuts
are properly tightened. See
Wheel Nut Torque under
Capacities and Specifications on
page 12 2.
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 If a Tire Goes Flat
on page 10 64.

When It Is Time for New

Tires

Various factors, such as
maintenance, temperatures, driving
speeds, vehicle loading, and road
conditions influence when you need
new tires.
One way to tell when it is time for
new tires is to check the treadwear
indicators, which appear when the
tires have only 1.6 mm (1/16 inch) or
less of tread remaining.
The vehicle needs new tires if any
of the following statements are true:
You can see the indicators at
three or more places around
the tire.
You can see cord or fabric
showing through the tire's
rubber.
The tread or sidewall is cracked,
cut, or snagged deep enough to
show cord or fabric.
The tire has a bump, bulge,
or split.
The tire has a puncture, cut,
or other damage that cannot be
repaired well because of the size
or location of the damage.
