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
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. Rota
-
tion 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 manufac
-
turer 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 Indicators” in this section. Refer to the
Tire and Loading Information placard or the
Vehicle Certification Label for the size desig
-
nation of your tire. The Load Index and
Speed Symbol for your tire will be found on
the original equipment tire sidewall.
See the Tire Sizing Chart example found in
the “Tire Safety Information” section of this
manual for more information relating to the
Load Index and Speed Symbol of a tire.
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 specifica
-
tions or capability. Failure to use equivalent
replacement tires may adversely affect the
safety, handling, and ride of your vehicle.
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.
