Tread Wear Indicators

Tread wear indicators are in the original
equipment tires to help you in determining
when your tires should be replaced.

These indicators are molded into the bottom
of the tread grooves. They will appear as
bands when the tread depth becomes a
1/16 of an inch (1.6 mm). When the tread is
worn to the tread wear indicators, the tire
should be replaced. Refer to “Replacement
Tires” in this section for further information.

Life Of Tire

The service life of a tire is dependent upon
varying factors including, but not limited to:

• Driving style.

• Tire pressure - Improper cold tire inflation

pressures can cause uneven wear patterns
to develop across the tire tread. These ab-
normal wear patterns will reduce tread life,
resulting in the need for earlier tire replace-
ment.

• Distance driven.

• Performance tires, tires with a speed rating

of V or higher, and Summer tires typically
have a reduced tread life. Rotation of these
tires per the vehicle scheduled mainte-
nance is highly recommended.

WARNING!

Tires and the spare tire should be replaced
after six years, regardless of the remaining
tread. Failure to follow this warning can
result in sudden tire failure. You could lose
control and have a collision resulting in
serious injury or death.

NOTE:

Wheel Valve Stem must be replaced as well
when installing new tires due to wear and tear
in existing tires.

Keep dismounted tires in a cool, dry place
with as little exposure to light as possible.
Protect tires from contact with oil, grease,
and gasoline.

Replacement Tires

The tires on your new vehicle provide a bal-
ance of many characteristics. They should be
inspected regularly for wear and correct cold
tire inflation pressures. The manufacturer
strongly recommends that you use tires
equivalent to the originals in size, quality and
performance when replacement is needed.
Refer to the paragraph on “Tread Wear Indi-
cators” in this section. Refer to the Tire and
Loading Information placard or the Vehicle
Certification Label for the size designation of
your tire. The Load Index and Speed Symbol
for your tire will be found on the original
equipment tire sidewall.
