2008 DODGE VIPER flat tire

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.

2. EconomyÐ
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Under inflation, also increases
tire rolling resistance and results in higher fuel consump-
tion.
3. Ride Comfort and Vehicle StabilityÐ
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 either on
the face of the driver's door or on the driver's side ªBº
pillar.
Some vehicles may have Supplemental Tire Pressure
Information for vehicle loads that are less than themaximum loaded vehicle condition. These pressure con-
ditions will be found in the ªSupplemental Tire Pressure
Informationº section of this manual.
The pressure should be checked and adjusted as well as
inspecting for signs of tire wear or visible damage at least
once a month. Use a good quality pocket-type gauge to

check tire pressure. Do not make a visual judgement
when determining proper inflation. Radial tires may look
properly inflated even when they are under inflated.
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
ªcold tire inflation pressure.º 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 1 mile
(1 km) after a 3 hour period. The cold tire inflation
pressure must not exceed the maximum inflation pres-
sure 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
12É F (7É C) of air temperature change. Keep this in mind
when checking tire pressure inside a garage, especially in
the winter.
Example: If garage temperature = 68É F (20É C) and the
outside temperature = 32É F (0É C) then the cold tire
inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12É F (7É 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
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

Many states have laws requiring tire replacement at this
point.
Life of Tire
The service life of a tire is dependent upon varying
factors including but not limited to:
²Driving style
²Tire pressure
²Distance driven
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.
162 STARTING AND OPERATING

TIRE PRESSURE MONITOR SYSTEM (TPMS)
Low Tire Indicator
If tire pressure falls below 20 psi (138 kpa), the Low Tire
Pressure Telltale in the Message Center will illuminate, a
chime will sound, and the words LOW TIRE will flash
slowly in the Liquid Crystal Display (LCD) panel in the
bottom of the speedometer. If tire pressure falls below 14
psi (97 kpa), the Low Tire Pressure Telltale will illumi-
nate, a chime will sound, and the words FLAT TIRE will
flash rapidly in the display. You should obtain immediate
service if the low tire indicator is activated.
NOTE:Each wheel on your vehicle contains a tire
pressure sensor. The TPMS learns the location of each
sensor though system programming. Although not re-
quired, the manufacturer recommends reprogramming
the TPMS after rotating the tires so that the system can
relearn each sensor 's location. See your authorized dealer
for system reprogramming.
CAUTION!
The Tire Pressure Monitor System (TPMS) has been
optimized for the original equipment tires and
wheels. The TPMS pressures have been established
for the tire size equipped on your vehicle. Undesir-
able operation or sensor damage may result when
using replacement equipment that is not of the same
size, type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use aftermarket tire sealants
or balance beads if your vehicle is equipped with the
TPMS, as damage to the sensors may result.
166 STARTING AND OPERATING

²You can use the TIREFIT air pump to inflate bicycle
tires. The kit also comes with two needles for inflating
sport balls, rafts, or like inflatable items. However, use
only the Black Air Pump Hose (6) and make sure the
Mode Select Knob (4) is in the Air Mode when
inflating such items to avoid injecting sealant into
them. The TIREFIT Sealant is only intended to seal
small punctures in the tire tread of a tire on this
vehicle.WARNING!
²Do not attempt to seal a tire on the side of the vehicle close to
traffic. Pull far enough off the road to avoid the danger of being
hit when using the TIREFIT kit.
²Do not use TIREFIT or drive the vehicle under the following
circumstances:
þ If the cut or puncture in the tire tread is approximately 0.24 in. (6
mm) or larger.
þ If the tire has any sidewall damage.
þ If the tire has any damage from driving with extremely low tire
pressure.
þ If the tire has any damage from driving on a flat tire.
þ If the wheel has any damage.
þ If you are unsure of the condition of the tire or the wheel.
²Keep TIREFIT away from open flame or heat source.
²TIREFIT is not a permanent flat tire repair. Have the tire inspected
and repaired or replaced after using TIREFIT. Do not exceed 55
mph (90 km/h) until having the tire repaired or replaced.
²A loose TIREFIT kit thrown forward in a collision or hard stop
could endanger the occupants of the vehicle. Always stow the
TIREFIT kit in the place provided.
Failure to follow these warnings can result in injuries that are
serious or fatal to you, your passengers, and others around you.

(A) Whenever You Stop to Use TIREFIT:
Turn on the vehicle's hazard warning flashers.
1. Verify that the valve stem (on the wheel with the
deflated tire) is in a position that is near to the ground.
This will allow the TIREFIT Hoses (6) and (7) to reach the
valve stem and keep the TIREFIT kit flat on the ground.
This will provide the best positioning of the kit when
injecting the sealant into the deflated tire and running the
air pump. Move the vehicle as necessary to place the
valve stem in this position before proceeding.
2. Place the transmission in Park (auto transmission) or
in Gear (manual transmission) and turn off the ignition.
3. Set the parking brake.
