DODGE CHALLENGER 2018 Vehicle Warranty

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
cargo should never exceed XXX kg or XXX lbs.” 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 passengers from
XXX kg or XXX lbs.
(4) The resulting figure equals the available amount of cargo and
luggage load capacity. For example, if “XXX” amount equals 1400 lbs.
and there will be five 150 lb passengers in your vehicle, the amount
of available cargo and luggage load capacity is 650 lbs. (1400-750
(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 transferred 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
passengers 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 carry capacity of your vehicle.
•For the following example, the combined weight of occupants and
cargo should never exceed 865 lbs (392 kg).

Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to the safe and satisfactory
operation of your vehicle. Four primary areas are affected by improper
tire pressure:
•Safety and Vehicle Stability
•Economy
•Tread Wear
•Ride Comfort
Safety
WARNING!
•Improperly inflated tires are dangerous and can cause collisions.
•Underinflation increases tire flexing and can result in overheating
and tire failure.
•Overinflation reduces a tire’s ability to cushion shock. Objects on
the road and chuckholes can cause damage that result in tire
failure.
•Overinflated or underinflated tires can affect vehicle handling and
can fail suddenly, resulting in loss of vehicle control.
•Unequal tire pressures can cause steering problems. You could lose
control of your vehicle.
•Unequal tire pressures from one side of the vehicle to the other can
cause the vehicle to drift to the right or left.
•Always drive with each tire inflated to the recommended cold tire
inflation pressure.
Both under-inflation and over-inflation affect the stability of the vehicle
and 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
left or right.

Fuel Economy
Underinflated tires will increase tire rolling resistance resulting in higher
fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause abnormal wear patterns
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. Over-inflation
produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the driver’s side
B-Pillar or rear edge of the driver’s side door.
At least once a month:
•Check and adjust tire pressure with a good quality pocket-type
pressure 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.
CAUTION!
After inspecting or adjusting the tire pressure, always reinstall the
valve stem cap. 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 three hours, or driven less than
1 mile (1.6 km) after sitting for a minimum of three hours. 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
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.
TIRES
13

Example: If garage temperature = 68°F (20°C) and the outside tempera-
ture = 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 and within posted
speed 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.
WARNING!
High speed driving with your vehicle under maximum load is
dangerous. 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).
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
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 following
criteria:
•The tire has not been driven on when flat.
•The damage is only on the tread section of your tire (sidewall damage
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 informa-
tion.
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 loss 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 driving a vehicle loaded at full capacity or to tow
a trailer while a tire is in the run flat mode.
See the tire pressure monitoring section for more information.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not spin your
vehicle’s wheels above 30 mph (48 km/h) or for longer than 30 seconds
continuously without stopping.
Refer to “Freeing A Stuck Vehicle” in “In Case Of Emergency” in your
Owner ’s Manual for further information.
TIRES

WARNING!
Fast spinning tires can be dangerous. Forces generated by excessive
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 continuously when you
are stuck, and do not 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.
These indicators are molded into the bottom of the tread grooves. They
will appear as bands when the tread depth becomes a 1/16 of an inch
(1.6 mm). When the tread is worn to the tread wear indicators, the tire
should be replaced. Refer to “Replacement Tires” in this section for
further information.

Life Of Tire
The service life of a tire is dependent upon varying factors including, but
not limited to:
•Driving style.
•Tire pressure - Improper cold tire inflation pressures can cause uneven
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
Summer tires typically have a reduced tread life. Rotation of these tires
per the vehicle scheduled maintenance is highly recommended.
WARNING!
Tires and the 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 a collision
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 pressures. The manufacturer 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 Indica-
tors” 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 Information”
section of this manual for more information relating to the Load Index
and Speed Symbol of a tire.
It is recommended to replace the two front tires or two rear tires as a pair.
Replacing just one tire can seriously affect your vehicle’s handling. If you
TIRES
17

ever replace a wheel, make sure that the wheel’s specifications match
those of the original wheels.
It is recommended you contact an authorized tire dealer or original
equipment dealer with any questions you may have on tire specifications
or capability. Failure to use equivalent replacement tires may adversely
affect the safety, handling, and ride of your vehicle.
WARNING!
•Do not use a tire, wheel size, load rating, or speed rating other than
that specified for your vehicle. Some combinations of unapproved
tires and wheels may change suspension dimensions and perfor-
mance characteristics, resulting in changes to steering, handling,
and braking of your vehicle. This can cause unpredictable han-
dling and stress to steering and suspension components. You could
lose control and have a collision 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 a collision.
•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 readings.

Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all seasons (Spring, Summer, Fall, and
Winter). Traction levels may vary between different all season tires. All
season tires can be identified by the M+S, M&S, M/S or MS designation on
the tire sidewall. Use all season tires only in sets of four; failure to do so may
adversely affect the safety and handling of your vehicle.
Summer Or Three Season Tires — If Equipped
Summer tires provide traction in both wet and dry conditions, and are
not intended to be driven in snow or on ice. If your vehicle is equipped
with Summer tires, be aware these tires are not designed for Winter or
cold driving conditions. Install Winter tires on your vehicle when
ambient temperatures are less than 40°F (5°C) or if roads are covered with
ice or snow. For more information, contact an authorized dealer.
Summer tires do not contain the all season designation or mountain/
snowflake symbol on the tire sidewall. Use Summer tires only in sets of
four; failure to do so may adversely affect the safety and handling of your
vehicle.
WARNING!
Do not use Summer tires in snow/ice conditions. You could lose
vehicle control, resulting in severe injury or death. Driving too fast
for conditions also creates the possibility of loss of vehicle control.
Snow Tires
Some areas of the country require the use of snow tires during the Winter.
Snow tires can be identified by a “mountain/snowflake” symbol on the
tire sidewall.
If you need snow tires, select tires equivalent in size
and type to the original equipment tires. Use snow
tires only in sets of four; failure to do so may adversely
affect the safety and handling of your vehicle.
Snow tires generally have lower speed ratings than
what was originally equipped with your vehicle and
should not be operated at sustained speeds over 75 mph (120 km/h). For
speeds above 75 mph (120 km/h) refer to original equipment or an
