2005 CHRYSLER CROSSFIRE tires

NOTE:The pressure in your tires changes with tem-
perature. A significant decrease in temperature could
reduce cold inflation pressure below the TPM setpoint.
For example, tires inflated to the proper cold inflation
pressure on a warm day or in a warm garage could
illuminate the TPM indicator lamp on the following day
if the temperature is very cold.ALWAYScheck the
pressure in your tires if the TPM lamp is illuminated.
Tire Chains
The RUD-maticDISC is the only tire chain system
approved for use on the Chrysler Crossfire.
Chains should only be used on the rear wheels and only
with the recommended winter mud and snow (M+S)
tires and wheels. Follow the manufacturer’s mounting
instructions.
Tire chains should only be driven on snow-covered roads
at speeds not to exceed 30 mph (48 km/h). Remove
chains as soon as possible when driving on roads without
snow.
When driving with tire chains, press the ESP control
switch to OFF.
CAUTION!
Damage to the vehicle may result if unapproved tire
chains are used.
Original Equipment Tires
Your vehicle is equipped with either sport performance
tires or all-season performance tires. The sport perfor-
mance tires offer the maximum road handling capability
in dry and wet weather conditions. The all-season per-
formance tires, while offering slightly less road handling
capability, are able to provide traction capability in snow
and ice conditions. Both types of tires are rated for high
speed operation. It is important that you know what type
of tires your vehicle is equipped with so that you
understand their traction and handling characteristics for
various road conditions. Replacement tires should be of
the same size and speed rating to continue to provide the
same level of performance you are accustomed to.
158 STARTING AND OPERATING

Snow Tires
Some areas of the country require the use of snow tires
during winter. See the recommended snow type winter
tire applications in this section.
WARNING!
Your vehicle may be equipped with sport perfor-
mance tires that are optimized for driving in dry and
wet weather conditions. However, these tires have
reduced traction capability in snow and ice. When
driving your Crossfire in these conditions with these
tires, you must take special care to maintain control
and avoid accidents. We recommend that you equip
your vehicle with “SNOW” or “ALL SEASON” tires
on all four wheels for driving in snowy and icy
conditions.
If you need snow tires, the recommended size for the
front and rear tires is the same size as the original
equipment front tires. This size tire on the rear allows the
use of tire chains on the rear wheels. Selection of this size
tire also requires the purchase of two additional wheels
with the same size specification as the original equip-
ment front wheels.
Snow tires may have a lower speed rating than factory
equipped tires and may not match the maximum vehicle
speed.
Snow tires should not be operated at sustained speeds
over 75 mph (120 km/h).

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 two 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.

•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.

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.
Tire Rotation Recommendations
Tires on the front and rear axles of vehicles operate at
different loads and perform different steering, driving
and braking functions. For these reasons, they wear at
unequal rates, and tend to develop irregular wear pat-
terns.These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on all season type
tires. Rotation will increase tread life, help to maintain
mud, snow and wet traction levels, and contribute to a
smooth, quiet ride.
Rotate your tires at intervals shown on the maintenance
schedules. More frequent rotation is permissible if de-
sired. The reasons for any rapid or unusual wear should
be corrected before rotating.
162 STARTING AND OPERATING

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 vehicle to pull to the left or right.
Alignment will not correct this condition. See your
authorized dealer for proper diagnosis.
Improper alignment will not cause vehicle vibration.
Vehicle vibration may be a result of tire and wheel
out-of-balance. Proper balancing will reduce vibration
and avoid tire cupping and spotty wear.

Traction
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is hydroplaning and may cause partial or
complete loss of vehicle control and stopping ability. To
reduce this possibility, the following precautions should
be observed:
1. Slow down during rainstorms or when roads are
slushy.
2. Slow down if the road has standing water or puddles.
3. Replace tires when tread wear indicators first become
visible.
4. Keep tires properly inflated.
5. Maintain enough distance between your vehicle and
the vehicle in front to avoid a collision in a sudden stop.
FREEING A STUCK VEHICLE
In order to free a stuck vehicle you must turn off the
Electronic Stability Program (ESP) before attempting to
“rock” the vehicle.
If your vehicle becomes stuck in mud, sand or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between Reverse
and Drive. Usually the least accelerator pedal pressure to
maintain the rocking motion without spinning the
wheels is most effective.
NOTE:ESP should be turned on again after freeing the
vehicle from a stuck condition.
CAUTION!
Racing the engine or spinning the wheels too fast
may lead to transmission/axle overheating and fail-
ure. It can also damage the tires. Do not spin the
wheels above 30 mph (48 km/h).
184 WHAT TO DO IN EMERGENCIES

Check the battery every four to six weeks to ensure that
the voltage is above 12.40. Voltage will drop more rapidly
in hot temperatures. If battery voltage drops below 12.40,
follow the battery recharge procedure in the Service
Manual.
•Check that the radiator coolant level of protection is to
at least -20°F (-29°C).
•Block the wheels. Do not apply the parking brake.
•Make sure that all tires are inflated to the optimum
pressure.
•Cut blocks of plywood about the same size of the tires.
Cover each block with indoor/outdoor carpeting and
place them between the tires and concrete. This will
prevent tire flat spotting.
•For long term storage, remove the tires and put the
vehicle up on blocks. Stack the tires on plywood and
cover with a tarp to prevent flat spotting.
•Move the wiper blades away from the windshield.
NOTE:To help prevent the battery from discharging
during shorter periods of inactivity, perform the follow-
ing:
1. Make sure that the rear liftgate/decklid, hood, and
doors are completely closed.
2. Make sure that the remote transmitter is operating and
that the battery is good.
3. Make sure that the hood, rear liftgate and door
switches are in adjustment.
4. Use the remote transmitter to set the alarm.
