never exceed XXX kg or XXX lbs” 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 “The combined weight of occupants and
ca
rgo should never exceed XXX kg or XXX lbs.” on your vehicle's
placard.
(2) Determine the combined weight of the driver and passengers that
wi
ll be riding in your vehicle.
(3) Subtract the combined weight of the driver and passengers from
XX
X kg or XXX lbs.

(4) The resulting figure equals the available amount of cargo and luggage
lo
ad capacity. For example, if “XXX” amount equals 1,400 lbs. and there
will be five 150 lb passengers in your vehicle, the amount of available
cargo and luggage load capacity is 650 lbs. (1,400-750 (5x150) = 650 lbs.)

(5) Determine the combined weight of luggage and cargo being loaded
on
the vehicle. That weight may not safely exceed the available cargo
and luggage load capacity calculated in Step 4.
(6) If your vehicle will be towing a trailer, load from your trailer will be
tr
ansferred to your vehicle. Consult this manual to determine how this
reduces the available cargo and luggage load capacity of your vehicle.
Metric Example For Load Limit
For example, if “XXX” amount equals 635 kg and there will be five 68 kg
pa
ssengers in your vehicle, the amount of available cargo and luggage
load capacity is 295 kg (635-340 (5x68) = 295 kg) as shown in step 4.

NOTE:

• If your vehicle will be towing a trailer, load from your trailer will be
transferred to your vehicle. The following table shows examples on
how to calculate total load, cargo/luggage, and towing capacities of
your vehicle with varying seating configurations and number and
size of occupants. This table is for illustration purposes only and
may not be accurate for the seating and load carrying capacity of
your vehicle.
• For the following example, the combined weight of occupants and
c
argo should never exceed 865 lbs (392 kg).

WARNING!
Overloading of your tires is dangerous. Overloading can cause
ti
re 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
op
eration of your vehicle. Four primary areas are affected by
improper tire pressure:
• Safety and Vehicle Stability
•

Economy
•
Tread Wear
•
Ride Comfort
S
afety
Both underinflation and overinflation affect the stability of the vehicle
a n

d can produce a feeling of sluggish response or over responsiveness
in the steering.

NOTE:

• Unequal tire pressures from side to side may cause erratic and
unpredictable steering response.
• Unequal tire pressure from side to side may cause the vehicle to drift
l
eft or right.
WARNING!
• Improperly inflated tires are dangerous and can cause collisions.
•
Underinflation increases tire flexing and can result in over -
h
eating and tire failure.
• Overinflation reduces a tire's ability to cushion shock. Objects
o
n the road and chuckholes can cause damage that result in tire
failure.
• Overinflated or underinflated tires can affect vehicle handling
a
nd can fail suddenly, resulting in loss of vehicle control.
• Unequal tire pressures can cause steering problems. You could
l
ose control of your vehicle.
• Unequal tire pressures from one side of the vehicle to the other
c
an cause the vehicle to drift to the right or left.
• Always drive with each tire inflated to the recommended cold
t
ire inflation pressure.

TIRES

Fuel Economy
Underinflated tires will increase tire rolling resistance resulting in
hi
gher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause abnormal wear
pa
tterns and reduced tread life, resulting in the need for earlier tire
replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable ride. Overinflation
pr
oduces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the driver side
B-
pillar or rear edge of the driver side door.
At least once a month:
• Check and adjust tire pressure with a good quality pocket-type
p
ressure gauge. Do not make a visual judgement when determining
proper inflation. Tires may look properly inflated even when they
are under-inflated.
• Inspect tires for signs of tire wear or visible damage.
I

nflation pressures specified on the placard are always “cold tire
in
flation 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 mile (1.6 km) after sitting for a minimum of three
ho

urs. The cold tire inflation pressure must not exceed the maximum
inflation pressure molded into the tire sidewall.
Check tire pressures more often if subject to a wide range of outdoor
te
mperatures, as tire pressures vary with temperature changes.
Tire pressures change by approximately 1 psi (7 kPa) per 12°F (7°C) of
ai
r temperature change. Keep this in mind when checking tire
pressure inside a garage, especially in the Winter. CAUTION!

After inspecting or adjusting the tire pressure, always reinstall the
va
lve stem cap. This will prevent moisture and dirt from entering
the valve stem, which could damage the valve stem.

TIRES
12
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
op
eration. DO NOT reduce this normal pressure build up or your tire
pressure will be too low.
Tire Pressures For High Speed Operation
FCA US LLC advocates driving at safe speeds and within posted
sp
eed limits. Where speed limits or conditions 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 operation.
Refer to an authorized tire dealer or original equipment vehicle dealer
for recommended safe operating speeds, loading and cold tire
inflation pressures.
Radial Ply Tires
WARNING!
High speed driving with your vehicle under maximum load is
da
ngerous. The added strain on your tires could cause them to
fail. You could have a serious collision. Do not drive a vehicle
loaded to the maximum capacity at continuous speeds above
75 mph (120 km/h).
WARNING!
Combining radial ply tires with other types of tires on your
ve
hicle will cause your vehicle to handle poorly. The instability
could cause a collision. Always use radial ply tires in sets of four.
Never combine them with other types of tires.

Tire Repair
If your tire becomes damaged, it may be repaired if it meets the
fo
llowing criteria:
• The tire has not been driven on when flat.
•
The damage is only on the tread section of your tire (sidewall
d
amage is not repairable).
• The puncture is no greater than a ¼ of an inch (6
mm).
Consult an authorized tire dealer for tire repairs and additional
in
formation.
Damaged Run Flat tires, or Run Flat tires that have experienced a loss
of
pressure should be replaced immediately with another Run Flat tire
of identical size and service description (Load Index and Speed
Symbol).
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive 50 miles (80 km) at
50

mph (80 km/h) after a rapid loss of inflation pressure. This rapid
lo

ss of inflation is referred to as the Run Flat mode. A Run Flat mode
occurs when the tire inflation pressure is of/or below 14 psi (96 kPa).
Once a Run Flat tire reaches the run flat mode it has limited driving
capabilities and needs to be replaced immediately. A Run Flat tire is
not repairable.
It is not recommended to drive a vehicle loaded at full capacity or to
to
w a trailer while a tire is in the Run Flat mode.
See the Tire Pressure Monitoring System section for more information.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not spin your
ve
hicle's wheels above 30 mph (48 km/h) or for longer than 30 seconds
co

ntinuously without stopping.
Refer to “Freeing A Stuck Vehicle” in “In Case Of Emergency” in your
Ow
ner’s Manual for further information.

Tread Wear Indicators
Tread wear indicators are in the original equipment tires to help you
in
determining when your tires should be replaced.
Tire Tread
These indicators are molded into the bottom of the tread grooves.
They will appear as bands when the tread depth becomes a 2/32 of an
inch (1.6 mm). When the tread is worn to the tread wear indicators, the
ti

re should be replaced.
Refer to “Replacement Tires” in this section for further information.
WARNING!
Fast spinning tires can be dangerous. Forces generated by
ex
cessive wheel speeds may cause tire damage or failure. A tire
could explode and injure someone. Do not spin your vehicle's
wheels faster than 30 mph (48 km/h) for more than 30 seconds
co

ntinuously when you are stuck, and do not let anyone near a
spinning wheel, no matter what the speed.

Life Of Tire
The service life of a tire is dependent upon varying factors including,
bu
t not limited to:
• Driving style.
•
Tire pressure - Improper cold tire inflation pressures can cause
u
neven wear patterns to develop across the tire tread. These
abnormal wear patterns will reduce tread life, resulting in the need
for earlier tire replacement.
• Distance driven.
•
Performance tires, tires with a speed rating of V or higher, and
S
ummer tires typically have a reduced tread life. Rotation of these
tires per the vehicle scheduled maintenance is highly recom -
mended.
Keep dismounted tires in a cool, dry place with as little exposure to
l i

ght as possible. Protect tires from contact with oil, grease, and
gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
ch
aracteristics. They should be inspected regularly for wear and
correct cold tire inflation pressures. FCA US LLC strongly
recommends that you use tires equivalent to the originals in size,
quality and performance when replacement is needed. Refer to the
paragraph on “Tread Wear Indicators” in this section. Refer to the Tire
and Loading Information placard or the Vehicle Certification Label for
the size designation of your tire. The Load Index and Speed Symbol
for your tire will be found on the original equipment tire sidewall.
See the Tire Sizing Chart example found in the “Tire Safety
In
formation” section of this manual for more information relating to
the Load Index and Speed Symbol of a tire.
WARNING!
Tires and the spare tire should be replaced after six years,
re
gardless of the remaining tread. Failure to follow this warning
can result in sudden tire failure. You could lose control and have a
collision resulting in serious injury or death.
