tire size DODGE DURANGO 2008 2.G User Guide

Loading
The vehicle maximum load on the tire must not exceed
the load carrying capacity of the tire on your vehicle. You
will not exceed the tire's load carrying capacity if you
adhere to the loading conditions, tire size, and cold tire
inflation pressures specified on the ªTire and Loading
Informationº placard and in the ªVehicle Loadingº sec-
tion of this manual.
NOTE:Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWR's) for the front and rear
axles must not be exceeded. For further information on
GAWR's, vehicle loading, and trailer towing, refer to the
ªVehicle Loadingº section of this manual.
To determine the maximum loading conditions of your
vehicle, locate the statement ªThe combined weight ofoccupants and cargo should never exceed XXX kg or XXX
lbs.º on the Tire and Loading Information placard. The
combined weight of occupants, cargo/luggage and
trailer tongue weight (if applicable) should never exceed
the weight referenced here.
Steps for Determining Correct Load Limit
1. Locate the statement ªThe combined weight of occu-
pants and cargo should never exceed XXX poundsº on
your vehicle's placard.
2. Determine the combined weight of the driver and
passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and pas-
sengers from XXX kilograms or XXX pounds.
310 STARTING AND OPERATING

WARNING!
Tires and spare tire should be replaced after six years,
regardless of the remaining tread. Failure to follow
this warning can result in sudden tire failure. You
could lose control and have an accident resulting in
serious injury or death.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
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
ªTread Wear Indicatorsº). Refer to the ªTire and Loading
Informationº 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.
320 STARTING AND OPERATING

WARNING!
²Do 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
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.
²Never 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.
²Failure 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
readings.
Alignment And Balance
Poor suspension alignment may result in:
²Fast tire wear.
²Uneven tire wear, such as feathering and one-sided
wear.
²Vehicle 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.
STARTING AND OPERATING 321

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.
SUPPLEMENTAL TIRE PRESSURE
INFORMATION Ð IF EQUIPPED
A light load vehicle condition is defined as two passen-
gers {150 lbs (68 kg) each} plus 200 lbs (91kg) of cargo.
Cold tire inflation pressures for a lightly loaded vehicle
will be found on the face of the driver's door.
TIRE CHAINS
Use ªClass Sº chains on your vehicle, or other traction
aids that meet SAE Type ªSº specifications.
NOTE:Chains must be the proper size for the vehicle,
as recommended by the chain manufacturer.
CAUTION!
To avoid damage to your vehicle, tires or chains, observe the
following precautions:
²Because of limited chain clearance between tires and other
suspension components, it is important that only chains in
good condition are used. Broken chains can cause serious
vehicle damage. Stop the vehicle immediately if noise
occurs that could suggest chain breakage. Remove the
damaged parts of the chain before further use.
²Install chains as tightly as possible and then retighten after
driving about 1/2 mile (0.8 km).
²Do not exceed 45 mph (72 km/h).
²Drive cautiously and avoid severe turns and large bumps,
especially with a loaded vehicle.
²Do not install tire chains on front wheels of 4x2 vehicles.
²Do not drive for a prolonged period on dry pavement.
²Observe the tire chain manufacturer's instructions on
method of installation, operating speed, and conditions for
usage. Always use the lower suggested operating speed of
the chain manufacturer if different than the speed recom-
mended by the manufacturer.
322 STARTING AND OPERATING

These cautions apply to all chain traction devices, includ-
ing link and cable (radial) chains.
Tire chain use is permitted only on the rear tires of your
truck.
NOTE:The use of class ªSº chains is permitted on your
vehicle with P245/70R17 tires.
CAUTION!
Do not use tire chains on 4x4 trucks equipped with
tires other than P245/70R17 tires. There may not be
adequate clearance for the chains and you are risking
structural or body damage to your vehicle. Do not use
tire chains on the 4X2 front wheels of your vehicle.
There may not be adequate clearance for the chains
and you are risking structural or body damage to
your vehicle.
SNOW TIRES
Snow tires should be of the same size and type construc-
tion as the front tires. Consult the manufacturer of the
snow tire to determine any maximum vehicle speed
requirement associated with the tire. These tires should
always be operated at the vehicle maximum capacity
inflation pressures under any load condition.
While studded tires improve performance on ice, skid
and traction capability on wet or dry surfaces may be
poorer than that of non-studded tires. Some states pro-
hibit studded tires; therefore, local laws should be
checked before using these tire types.

For example, your vehicle has a recommended cold
(parked for more than 3 hours) placard of 33 (227 kPa). If
the ambient temperature is 68ÉF (20ÉC) and the measured
tire pressure is 28 psi (193 kPa), a temperature drop to
20ÉF (-7ÉC) will decrease the tire pressure to approxi-
mately 24 psi (165 kPa). This tire pressure is sufficiently
low enough to turn ON the Tire Pressure Monitoring
lamp. Driving the vehicle may cause the tire pressure to
rise to approximately 28 psi (193 kPa), but the Tire
Pressure Monitoring lamp will still be ON. In this situa-
tion, the Tire Pressure Monitoring lamp will turn OFF
only after the tires have been inflated to the vehicle's
recommended cold placard pressure value.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 system operation or sensor
damage may result when using replacement equip-
ment that is not of the same size, type, and/or style.
After-market 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.
CAUTION!
After inspecting or adjusting the tire pressure always
reinstall the valve stem cap. This will prevent mois-
ture and dirt from entering the valve stem, which
could damage the Tire Pressure Monitoring Sensor.
326 STARTING AND OPERATING

²Tire Pressure Monitoring Telltale Lamp
The Tire Pressure Monitoring Telltale Lamp will
illuminate in the instrument cluster, and an au-
dible chime will be activated when one or more of
the four active road tire pressures are low. Should this
occur, you should stop as soon as possible, check the
inflation pressure of each tire on your vehicle, and inflate
each tire to the vehicle's recommended cold placard
pressure value. The system will automatically update
and the Tire Pressure Monitoring Lamp will extinguish
once the updated tire pressures have been received. The
vehicle may need to be driven for up to 10 minutes above
15 mph (25 km/h) to receive this information.
The Tire Pressure Monitoring Telltale Lamp will flash on
and off for 75 seconds, and remain on solid when a
system fault is detected. The system fault will also sound
a chime. If the ignition key is cycled, this sequence will
repeat, providing the system fault still exists. The TirePressure Monitoring Telltale Lamp will turn off when the
fault condition no longer exists. A system fault can occur
by any of the following scenarios: 1) Jamming due to
electronic devices or driving next to facilities emitting the
same Radio Frequencies as the TPM sensors. 2) Installing
some form of aftermarket window tinting that affects
radio wave signals. 3) Lots of snow or ice around the
wheels or wheel housings. 4) Using tire chains on the
vehicle. 5) Using wheels/tires not equipped with TPM
sensors.
NOTE: Your vehicle is equipped with a non-matching
full size spare wheel and tire assembly.
1. This spare tire does not have a tire pressure monitor-
ing sensor. Therefore, the TPMS will not monitor the tire
pressure in the spare tire.
2. If you install the full size spare tire in place of a road
tire that has a pressure below the low-pressure warning
328 STARTING AND OPERATING

limit, upon the next ignition key cycle, a chime will
sound and the TPM Telltale Light will still turn ON due
to the low tire.
3. However, after driving the vehicle for up to 10 min-
utes above 15 mph (25 km/h), the TPM Telltale Light will
flash on and off for 75 seconds and then remain on solid.
4. For each subsequent ignition key cycle, a chime will
sound and the TPM Telltale Light will flash on and off for
75 seconds and then remain on solid.
5. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the full size spare tire,
the TPMS will update automatically and the TPM Telltale
Light will turn OFF, as long as no tire pressure is below
the low-pressure warning limit in any of the four active
road tires. The vehicle 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.Premium 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 the Receiver Module.
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 consists of the following components:
²Receiver Module.
²4 Tire Pressure Monitoring Sensors.
²3 Trigger Modules (mounted in three of the four wheel
wells).
²Various Tire Pressure Monitoring System Messages,
which display in the Electronic Vehicle Information
Center (EVIC), and a graphic displaying tire pressures.

affects radio wave signals. 3) Lots of snow or ice around
the wheels or wheel housings. 4) Using tire chains on the
vehicle. 5) Using wheels/tires not equipped with TPM
sensors.
NOTE:Your vehicle is equipped with a non-matching
full size spare wheel and tire assembly.
1. This spare tire does not have a tire pressure monitor-
ing sensor. Therefore, the TPMS will not monitor the tire
pressure in the spare tire.
2. If you install the full size spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition key cycle, a chime will
sound and the TPM Telltale Light will still turn ON. In
addition, the graphic in the EVIC will still display a
flashing pressure value.
3. However, after driving the vehicle for up to 10 min-
utes above 15 mph (25 km/h), the TPM Telltale Light willflash on and off for 75 seconds and then remain on solid.
The EVIC will display a ªCHECK TPM SYSTEMº mes-
sage for 3 seconds and then display dashes (- - -) in place
of the pressure value.
4. For each subsequent ignition key cycle, a chime will
sound and the TPM Telltale Light will flash on and off for
75 seconds and then remain on solid. The EVIC will
display a ªCHECK TPM SYSTEMº message for 3 sec-
onds, and then display dashes (- - -) in place of a pressure
value.
5. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the full size spare tire,
the TPMS will update automatically. In addition, the
TPM Telltale Light will turn OFF and the graphic in the
EVIC will display a new pressure value instead of dashes
(- - -), as long as no tire pressure is below the low-
pressure warning limit in any of the four active road tires.

Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the component in the
system with the lowest load carrying capacity (axle,
springs, tires, or wheels).
Heavier axles or suspension components sometimes
specified by purchasers for increased durability do not
necessarily increase the vehicle's GVWR.
Tire Size
This is the minimum allowable tire size for your vehicle.
Replacement tires must be equal to the load capacity of
this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure (Cold)
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Loading
The actual total weight and the weight of the front and
rear of your vehicle at the ground can best be determined
by weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commer-
cial scale to insure that the GVWR has not been exceeded.
The weight on the front and rear of the vehicle should
