2008 DODGE VIPER load capacity

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 Tire and Loading
Information placard and in the ªVehicle Loadingº section
of this manual.
NOTE:Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWRs) for the front and rear
axles must not be exceeded. For further information on
GAWRs, 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.
154 STARTING AND OPERATING

4. The resulting figure equals the available amount of
cargo and luggage load capacity. For example, if ªXXXº
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 (295 kg) (since 5 x
150 = 750, and 1400 ± 750 = 650 lbs (295 kg)
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 thismanual to determine how this reduces the available
cargo and luggage load capacity of your vehicle.
NOTE:The following table shows examples on how to
calculate total load, cargo/luggage, and towing capaci-
ties 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.
NOTE:For the following example, the combined weight
of occupants and cargo should never exceed 865 lbs (392
kg).

WARNING!
Overloading of your tires is dangerous. Overloading
can cause tire failure, affect vehicle handling, and
increase your stopping distance. Use tires of the
recommended load capacity for your vehicle. Never
overload them.
TIRES Ð GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Three primary
areas are affected by improper tire pressure:1. SafetyÐ
WARNING!
²Improperly inflated tires are dangerous and can cause
accidents.
²Under inflation increases tire flexing and can result in tire
failure.
²Over inflation reduces a tire's ability to cushion shock.
Objects on the road and chuckholes can cause damage that
result in tire failure.
²Unequal tire pressures can cause steering problems. You
could lose control of your vehicle.
²Over inflated or under inflated tires can affect vehicle
handling and can fail suddenly, resulting in loss of vehicle
control.
²Unequal tire pressures from one side of the vehicle to the
other can cause the vehicle to drift to the right or left.
²Always drive with each tire inflated to the recommended
cold tire inflation pressure.

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).
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.
160 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 sus-
pension dimensions and performance characteris-
tics, resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpredict-
able handling and stress to steering and suspen-
sion 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.

WARNING!
²Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
²Never add fuel to the vehicle when the engine is
running.
²A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on
the ground while filling.NOTE:
²Tighten the gas cap until you hear a ªclickingº sound.
This is an indication that the gas cap is tightened
properly. The Malfunction Indicator Light in the in-
strument cluster may turn on if the gas cap is not
secured properly. Make sure that the gas cap is tight-
ened each time the vehicle is refueled.
²If the gas cap is lost or damaged, be sure the replace-
ment cap is for use with this vehicle.
