• The puncture is no greater than a ¼ of an inch
(6 mm).
Consult an authorized tire dealer for tire repairs and
additional information.
Damaged Run Flat tires, or Run Flat tires that have
experienced a loss of pressure should be replaced
immediately with another Run Flat tire of identical
size and service description (Load Index and Speed
Symbol).
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.
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 continu-
ously without stopping.
Refer to "Freeing A Stuck Vehicle" in "In Case Of
Emergency" 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.
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
1 — Worn Tire
2 — New Tire
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.
