These indicators are molded into the bottom of the
tread grooves. They will appear as bands when the
tread depth becomes 1/16 of an inch (1.6 mm). When
the tread i s worn to the tread wear indicators, the tire
should be re placed .

Life Of Tire
The service life of a tire is dependent upon varying fac-
tors 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 abno rmal wear patterns will
reduce tread life, resulting in the need for earlier tire
replacement.
•
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 maintenance 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 install-
ing new tires due to wear and tear in existing tires.
Keep dismou nted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, greas e, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressures. The
manufacturer strongly recommends using tires equiva-
lent to the originals in size, quality and performance
when replacement is needed. Refer to the paragraph
on “Tread Wear Indicators” in this sec tio n. Refer to the
Tire And Loa ding Information Placard or the Vehicle
Certificat ion Label for the size designation of your tire.
The Load Index a nd Speed Symbol for your tire will be
found on the original equipment tire sidewall.
For more information relating to t he Load Index and
Speed Symbol of a tire
page 321.
It is recomme nde d to replace the two front tires or two
rear tires as a pair. Replacing just one tire can seriously
affect your vehicle’s handling. If you ever replace a
wheel, make sure that the wheel’s specifications match
those of the original wheels .
It is recomme nde d you contact an authorized tire
dealer or original equipment dealer with any questions
you may have on tire specifications or capability. Failure
to use equivalent replacement tires may adversely
affect the safety, handling, and ride of your vehicle.
WARNING!
•
Do not use a tire, wheel size, load rating, or speed
rating other than that specified for your vehicle.
Some combinations of unapproved tires and
wheels may change suspension dimensions and
performance characteristics, resulting in changes
to steering, handling, and braking of your vehicle.
This can cause unpredictable handling and stress
to steering and suspension components. You could

WARNING!
lose control and have a collision resulting in seri-
ous injury or death. Use only the tire and wheel
sizes with load ratings approved for your vehicle.
•
Never use a tire with a smaller load index or capac-
ity, other than what was originally equipped on
your vehicle. Using a tire with a smaller load index
could result in tire overloading and failure. You
could lose control and have a collision.
•
Failure to equip your vehicle with tires having
adequate spe ed capability can result in sudden
tire failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a di fferent size
may result in false speedometer and odometer
readings.
TIRE TYPES
All Season Tires — If Equipped
All Season tire s provide traction for all seasons (Spring,
Summer, Autumn, and Winter). Traction levels may vary
between different all season tires. All season tires can
be identified by the M+S, M& S, M/S or MS designation
on the tir e sidewall. Use all season tires only in sets of
four; failure to do so may adversely affect the safety
and handling of your vehicle.
