Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive
50 miles (80 km) at 50 mph (80 km/h) after a
rapid loss of inflation pressure. This rapid loss
of inflation is referred to as the Run Flat mode.
A Run Flat mode occurs when the tire inflation
pressure is of/or below 14 psi (96 kPa). Once a
Run Flat tire reaches the run flat mode it has
limited driving capabilities and needs to be
replaced immediately. A Run Flat tire is not
repairable. When a run flat tire is changed after
driving with underinflated tire condition, please
replace the TPM sensor as it is not designed to
be reused when driven under run flat mode
14 psi (96 kPa) condition.
NOTE:
TPM Sensor must be replaced after driving the
vehicle on a flat tire condition.
It is not recommended driving a vehicle loaded
at full capacity or to tow a trailer while a tire is in
the run flat mode.
See the tire pressure monitoring section for
more information.
Tire Spinning
When stuck in mud, sand, snow, or ice
conditions, do not spin your vehicle's wheels
above 30 mph (48 km/h) or for longer than
30 seconds continuously without stopping.
Refer to “Freeing A Stuck Vehicle” in “In Case Of
Emergency” for further information.
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 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.
WARNING!

Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause tire damage or failure. A tire could
explode and injure someone. Do not spin your
vehicle's wheels faster than 30 mph (48 km/h)
for more than 30 seconds continuously when
you are stuck, and do not let anyone near a
spinning wheel, no matter what the speed.

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 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 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 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 designation 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 specifications 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.
WARNING!
Do not use a tire, wheel size, load rating, or
speed rating other than that specified for
your vehicle. Some combinations of unap
-
proved 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 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.

increase tread life, help to maintain mud, snow
and wet traction levels and contribute to a
smooth, quiet ride.
Refer to the “Maintenance Plan” for the proper
maintenance intervals. More frequent rotation
is permissible if desired. The reasons for any
rapid or unusual wear should be corrected prior
to rotation being performed.
The suggested rotation method is the “rearward
cross” shown in the following diagram. This
rotation pattern does not apply to some
directional tires that must not be reversed.
Tire Rotation (Rearward Cross)
Dual Rear Wheels — If Equipped
The tires used on dual wheel assemblies should
be matched for wear to prevent overloading one
tire in a set. To check if tires are even, lay a
straight edge across all four tires. The straight
edge should touch all the tires.
Tire Rotation

NOTE:
If your vehicle is equipped with a Tire Pressure
Information System (TPIS):
The Tire Pressure Information System (TPIS)
uses unique sensors in the inner rear wheels
to help identify them from the outer rear
wheels, because of this, the inner and outer
wheel locations can’t be switched.
After a tire rotation is completed, as shown
below, the system can auto learn the loca -
tions of each sensor ID. Auto learning/local -
ization occurs when the vehicle ignition
status is changed from Off to On and speeds
of greater than 5 mph (8km/h) are obtained
and remain over 5 mph (8km/h) for at about
a 15 minute period. You may need to drive
for 20 minutes to account slower speeds and
stops.
If the tires are rotated incorrectly, The auto
localization of the TPIS sensors will fail to
locate correctly resulting in incorrect loca -
tions for the pressure values displayed in the
instrument cluster.
CAUTION!
3500 Dual Rear Tires may only have one
approved direction of rotation. This is to
accommodate the asymmetrical design
(tread pattern) of the On/Off-Road tire and
the use of Outline White Letter (OWL) tires.
