2008 DODGE CHARGER SRT flat tire

WARNING!
Overloading of your tires is dangerous. Overloading
can cause tire failure, affect vehicle handling, and
increase your stopping distance. Use tires of the
recommended load capacity for your vehicle. Never
overload them.
TIRES — GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Three primary
areas are affected by improper tire pressure:1. Safety—
WARNING!
•Improperly inflated tires are dangerous and can
cause accidents.
•Under-inflation increases tire flexing and can result
in tire failure.
•Over-inflation reduces a tire’s ability to cushion
shock. Objects on the road and chuckholes can cause
damage that result in tire failure.
•Unequal tire pressures can cause steering problems.
You could lose control of your vehicle.
•Over-inflated or under-inflated tires can affect ve-
hicle handling and can fail suddenly, resulting in loss
of vehicle control.
•Unequal tire pressures from one side of the vehicle to
the other can cause the vehicle to drift to the right or
left.
•Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
300 STARTING AND OPERATING

2. Economy—
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Under-inflation, also increases
tire rolling resistance and results in higher fuel consump-
tion.
3. Ride Comfort and Vehicle Stability—
Proper tire inflation contributes to a comfortable ride.
Over-inflation produces a jarring and uncomfortable
ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed either on
the face of the driver’s door or on the driver’s side
B-pillar.
Some vehicles may have supplemental tire pressure
information for vehicle loads that are less than themaximum loaded vehicle condition. These pressure con-
ditions will be found in the “Supplemental Tire Pressure
Information” section of this manual.
The pressure should be checked and adjusted as well as
inspecting for signs of tire wear or visible damage at least
once a month. Use a good quality pocket-type gauge to

check tire pressure. Do not make a visual judgement
when determining proper inflation. Radial tires may look
properly inflated even when they are under-inflated.
CAUTION!
After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap (if equipped). This
will prevent moisture and dirt from entering the
valve stem, which could damage the valve stem.
Inflation pressures specified on the placard are always
“cold tire inflation pressure.” Cold tire inflation pressure
is defined as the tire pressure after the vehicle has not
been driven for at least three hours, or driven less than 1
mi (1 km) after a three hour period. The cold tire inflation
pressure must not exceed the maximum inflation pres-
sure molded into the tire sidewall.Check tire pressures more often if subject to a wide range
of outdoor temperatures, as tire pressures vary with
temperature changes.
Tire pressures change by approximately 1 psi (7 kPa) per
12° F (7° C) of air temperature change. Keep this in mind
when checking tire pressure inside a garage, especially in
the Winter.
Example: If garage temperature = 68°F (20°C) and the
outside temperature = 32°F (0°C) then the cold tire
inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12°F (7°C) for this
outside temperature condition.
Tire pressure may increase from 2 to 6 psi (13 to 40 kPa)
during operation. DO NOT reduce this normal pressure
build up or your tire pressure will be too low.
302 STARTING AND OPERATING

Tire Pressures for High Speed Operation
The manufacturer advocates driving at safe speeds
within posted speed limits. Where speed limits or condi-
tions are such that the vehicle can be driven at high
speeds, maintaining correct tire inflation pressure is very
important. Increased tire pressure and reduced vehicle
loading may be required for high-speed vehicle opera-
tion. Refer to original equipment or an authorized tire
dealer for recommended safe operating speeds, loading
and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle under maxi-
mum load is dangerous. The added strain on your
tires could cause them to fail. You could have a
serious accident. Don’t drive a vehicle loaded to the
maximum capacity at continuous speeds above 75
mph (120 km/h).
Radial-Ply Tires
WARNING!
Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause an accident. Al-
ways use radial ply tires in sets of four (or six, in case
of trucks with dual rear wheels). Never combine
them with other types of tires.
Cuts and punctures in radial tires are repairable only in
the tread area because of sidewall flexing. Consult your
authorized tire dealer for radial tire repairs.

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 pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed. (Refer to the paragraph on
“Tread Wear Indicators”). Refer to the “Tire and Loading
Information” placard for the size designation of your tire.
The service description and load identification will be
found on the original equipment tire. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle. We recommend
that you contact your original equipment or an autho-
rized tire dealer with any questions you may have on tire
specifications or capability.WARNING!
•Do not use a tire, wheel size or rating other than that
specified for your vehicle. Some combinations of
unapproved tires and wheels may change suspension
dimensions and performance characteristics, result-
ing 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 an accident 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
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 an accident.
•Failure to equip your vehicle with tires having ad-
equate speed capability can result in sudden tire
failure and loss of vehicle control.
306 STARTING AND OPERATING

Tire Rotation — All Season Tires
The suggested rotation method for vehicles equipped
with all season tires is the “forward-cross” as shown in
the following diagram.
TIRE PRESSURE MONITOR SYSTEM (TPMS) — IF
EQUIPPED
•
The Tire Pressure Monitor System (TPMS) will warn
the driver of a low tire pressure based on the vehicle
recommended cold placard pressure.
•The tire pressure will vary with temperature by about
1 psi (6.9 kPa) for every 12°F (6.5°C). This means that
when the outside temperature decreases, the tire pres-
sure will decrease. Tire pressure should always be set
based on cold inflation tire pressure. This is defined as
the tire pressure after the vehicle has not been driven
for at least three hours, or driven less than 1 mi (1 km)
after a three hour period. The cold tire inflation
pressure must not exceed the maximum inflation
pressure molded into the tire sidewall. Refer to the
“Tires – General Information” in this section for infor-
mation on how to properly inflate the vehicle’s tires.

The tire pressure will also increase as the vehicle is
driven - this is normal and there should be no adjust-
ment for this increased pressure.
•The TPMS will warn the driver of a low tire pressure
if the tire pressure falls below the low-pressure warn-
ing limit for any reason, including low temperature
effects and natural pressure loss through the tire.
•The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not
turn off until the tire pressure is at or above the
recommended cold placard pressure. Once the low tire
pressure warning (Tire Pressure Monitoring Telltale
Light) illuminates, you must increase the tire pressure
to the recommended cold placard pressure in order for
the Tire Pressure Monitoring Telltale Light to turn off.
The system will automatically update and the Tire
Pressure Monitoring Telltale Light will turn off once
the system receives the updated tire pressures. Thevehicle may need to be driven for up to 10 minutes
above 15 mph (25 km/h) in order for the TPMS to
receive this information.
For example, your vehicle may have a recom-
mended cold (parked for more than three hours)
placard pressure of 30 psi (207 kPa). If the ambient
temperature is 68°F (20°C) and the measured tire
pressure is 27 psi (186 kPa), a temperature drop to
20°F (-7°C) will decrease the tire pressure to ap-
proximately 26 psi (179 kPa). This tire pressure is
sufficiently low enough to turn ON the Tire Pressure
Monitoring Telltale Light. Driving the vehicle may
cause the tire pressure to rise to approximately 27
psi (186 kPa), but the Tire Pressure Monitoring
Telltale Light will still be ON. In this situation, the
Tire Pressure Monitoring Telltale Light will turn
OFF only after the tires are inflated to the vehicle’s
recommended cold placard pressure value.
312 STARTING AND OPERATING

CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when us-
ing replacement equipment that is not of the same
size, type, and/or style. Aftermarket wheels can
cause sensor damage. Do not use aftermarket tire
sealants or balance beads if your vehicle is
equipped with a TPMS, as damage to the sensors
may result.
•After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure Moni-
toring Sensor.NOTE:
•The TPMS is not intended to replace normal tire care
and maintenance or to provide warning of a tire failure
or condition.
•The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
•Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
•The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if under-inflation has not reached the
level to trigger illumination of the Tire Pressure Moni-
toring Telltale Light.
