384SERVICING AND MAINTENANCE
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 being driven in a Run Flat
mode 14 psi (96 kPa) condition, please replace the
TPMS sensor as it is not designed to be reused.
NOTE:TPMS 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 System section
for more information Úpage 264.
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.
For further information Ú page 325.
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 Ú
page 385.
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 pres -
sures 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 scheduled maintenance is highly
recommended.
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.

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.
