2006 CHRYSLER CROSSFIRE inflation pressure

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. Underinflation also increases tire
rolling resistance and results in higher fuel consumption.
3. Ride Comfort and Vehicle Stability—
Proper tire inflation contributes to a comfortable ride.
Overinflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure for passenger cars
is listed on either the face of the driver’s door or the
driver’s side “B” pillar.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 underinflated.

160 STARTING AND OPERATING

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 3 hours, or driven less than 1 mile
(1 km) after a 3 hour period. The cold tire inflation
pressure must not exceed the maximum inflation pres-
sure molded into the tire side wall.
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.
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.

Tread Wear Indicators
Tread wear indicators are in the original equipment tires
to help you in determining when your tires should be
replaced.
These indicators are molded into the bottom of the tread
grooves and will appear as bands when the tread depth
becomes 1/16 inch (2 mm). When the indicators appear
in 2 or more adjacent grooves, the tire should be replaced.
Many states have laws requiring tire replacement at this
point.
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 (see the paragraph on tread
wear indicators). Refer to the Tire and Loading Informa-
tion 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, han-
dling, and ride of your vehicle. We recommend that you
contact your original equipment or an authorized tire
dealer with any questions you may have on tire specifi-
cations or capability.

•When obtaining replacement tires, assure that the
tires are specified for replacement on the Cross-
fire. Tires with the same size, speed, or load
ratings that are specified for replacement on other
vehicles may not properly fit on the original
equipment wheels of your vehicle.
•Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combina-
tions of unapproved tires and wheels may change
suspension dimensions and performance charac-
teristics, resulting in changes to steering, han-
dling, 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, other 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
adequate speed capability can result in sudden
tire failure and loss of vehicle control.
164 STARTING AND OPERATING

CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings. Check with your authorized dealer before
replacing tires with a different size.
Alignment And Balance
The suspension components of your vehicle should be
inspected and aligned when needed to obtain full tire
tread mileage
Poor suspension alignment may result in:
•Fast tire wear.
•Uneven tire wear, such as feathering and one-sided
wear.
•Vehicle pull to right or left.
Tires may also cause the vehicle to pull to the left or right.
Alignment will not correct this condition. See your dealer
for proper diagnosis.Improper alignment will not cause vehicle vibration.
Vibration may be a result of tire and wheel out-of-
balance. Proper balancing will reduce vibration and
avoid tire cupping and spotty wear.
TIRE PRESSURE MONITOR SYSTEM (If
Equipped)
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to a computer which monitors for low pressure.
If low pressure is measured, the TPMS Telltale Lamp will
illuminate.
NOTE:It is particularly important, for you to check the
tire pressure in all of your tires regularly and to maintain
the proper pressure.
The TPMS informs you of a low tire pressure condition.
If this occurs, correct your tire inflation pressure as soon
as possible, and inspect all of your tires. Be sure to use a
high quality gauge when adjusting pressure. The TPMS
is designed to periodically monitor your tire pressure but

cannot be expected to function as a tire pressure gauge.
There can be a delay between the instant you adjust the
air pressure in a tire and when the system updates the
display. The TPMS is not intended to provide you with
notification of rapid air loss.
The TPMS will cause the Telltale lamp in the instrument
cluster to illuminate whenever the pressure in one tire
falls 25% below the recommended pressure shown on the
tire label.
NOTE:A TPMS does not replace normal tire mainte-
nance.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures have
been established for the tire size equipped on your
vehicle. Undesirable operation or sensor damage
may result when using replacement equipment that
is not of the same size, type, and/or style. Aftermar-
ket wheels can cause sensor damage. Do not use
aftermarket tire sealant or balance beads as damage
to the sensors may result. The standard TIREFIT
system (see Tirefit Tire Repair and Jacking Instruc-
tions in the What To Do In Emergencies section) is
specifically designed to operate in conjunction with
the TPMS, and will not damage the sensors.
NOTE:The pressure in your tires changes with tem-
perature. A significant decrease in temperature could
reduce cold inflation pressure below the TPMS setpoint.
For example, tires inflated to the proper cold inflation
pressure on a warm day or in a warm garage could
illuminate the TPMS Telltale lamp on the following day if
