(Continued)
Tread Wear Indicators
Tread wear indicators are in the original equipment tires to
help you in determining when your tires should be
replaced.

Tire Tread

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 is
worn to the tread wear indicators, the tire should be
replaced.
For further information
Úpage 354.
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 abnormal 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 sched-
uled maintenance is highly recommended.
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 balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressures. The
manufacturer strongly recommends using tires equivalent
to the originals in size, quality and performance when
replacement is needed. Refer to the paragraph on “Tread
Wear Indicators” 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. For more information relating to the Load Index and Speed
Symbol of a tire
Úpage 346.
It is recommended 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 recommended 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.
1 — Tread Wear Indicators
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.

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 perfor -
mance 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
lose control and have a collision resulting in serious
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 capacity,
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.
