2005 DODGE GRAND CARAVAN tires

check tire pressure. Do not make a visual judgement
when determining proper inflation. Radial tires may look
properly inflated even when they are underinflated.
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 1mile
(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.318 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). STARTING AND OPERATING 319

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 6, 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. Compact Spare Tire — If Equipped
The compact spare is for temporary emergency use with
radial tires. It is engineered to be used on your style
vehicle only. Since this tire has limited tread life, the
original tire should be repaired (or replaced) and rein-
stalled at the first opportunity.
WARNING!Temporary use spare tires are for emergency use
only. With these tires, do not drive more than 50 mph
(80 km/h). Temporary-use spare tires have limited
tread life. When two or more tread wear indicators
appear in adjacent grooves, the temporary use spare
tire needs to be replaced. Be sure to follow the
warnings which apply to your spare. Failure to do so
could result in spare tire failure and loss of vehicle
control.320 STARTING AND OPERATING

WARNING!The limited use spare tires are for emergency use
only. Installation of this limited use spare tire affects
vehicle handling. With this tire, do not drive more
than 60 mph (100 km/h). Keep inflated to the cold
tire inflation pressure listed on either your tire
placard or limited use spare tire and wheel assembly.
Replace (or repair) the original tire at the first
opportunity and reinstall it on your vehicle. Failure
to do so could result in loss of vehicle control.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle ’ s wheels above 35 mph (55 km/h).
See the paragraph on Freeing A Stuck Vehicle in Section
6 of this manual. WARNING!Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire dam-
age or failure. A tire could explode and injure
someone. Do not spin your vehicle ’ s wheels faster
than 35 mph (55 km/h) when you are stuck. And
don ’ t 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.322 STARTING AND OPERATING

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. STARTING AND OPERATING 323

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 suspen-
sion dimensions and performance characteristics,
resulting in changes to steering, handling, and brak-
ing of your vehicle. This can cause unpredictable
handling and stress to steering and suspension com-
ponents. 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.
Alignment And Balance
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.324 STARTING AND OPERATING

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 (TPM) system uses
wireless technology with wheel rim mounted electronic
sensors to monitor tire pressure levels (EXCLUDING
THE SPARE TIRE). Sensors, mounted to each wheel as
part of the valve stem, transmit tire pressure readings to
a receiver located in the instrument panel.
NOTE: The tire pressure monitoring system on your
vehicle will warn you when one of your tires is signifi-
cantly underinflated and when some combinations of
your tires are significantly underinflated. It is particularly
important, therefore, for you to check the tire pressure in
all of your tires regularly and maintain proper pressure. 1,2,3, OR 4 TIRE(S) LOW PRESSURE
Low tire pressure levels of 28 psi [1.9 bars] (193 kPa) or
less detected in one or more tires.
Inspect all tires for proper inflation pressure, once proper
tire pressure has been set the TPM system warning will
reset automatically once ignition switch has been turned
ON.
1,2,3, OR 4 TIRE(S) HIGH PRESSURE
High tire pressure levels of 48 psi [3.3 bars] (330 kPa) or
more detected in one or more tires.
Inspect all tires for proper inflation pressure, once proper
tire pressure has been set the TPM system warning will
reset automatically once ignition switch has been turned
ON. STARTING AND OPERATING 325

CHECK TPM SYSTEM
The Tire Pressure Monitor System (TPM) system requires
service.
See your authorized dealer for service.
CAUTION!The TPM system has been optimized for the original
equipment tires and wheels. TPM system pressures
have been established for the tire size equipped on
your vehicle. Undesirable operation or sensor dam-
age may result when using replacement equipment
that is not of the same size, type, and/or style.
After-market wheels can cause sensor damage. Do
not use tire sealant or balance beads if your vehicle
is equipped with TPM system as damage to the
sensors may result. NOTE:
• The TPM system can inform the driver of a low tire
pressure condition of 28 psi [1.9 bars] (193 kPa) or less,
or high a tire pressure condition of 48 psi [3.3 bars]
(330 kPa) or more.
• The TPM system is not intended to replace normal tire
care and maintenance, nor to provide warning of a tire
failure or condition.
• The TPM system should not be used as a tire pressure
gauge while adjusting your tire pressure.
CAUTION!After inspecting or adjusting the tire pressure al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt entry into the valve stem, which
could damage the wheel rim sensor.326 STARTING AND OPERATING
