2009 DODGE VIPER flat tire

WARNING! (Continued)
•Unequal tire pressures from one side of the ve-
hicle to the other can cause the vehicle to drift to
the right or left.
•Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
Economy
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
consumption.
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.
Some vehicles may have Supplemental Tire Pressure
Information for vehicle loads that are less than the
maximum loaded vehicle condition. These pressure con-
ditions will be found in the “Supplemental Tire Pressure
Information” 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
“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 a three hour period. The cold tire
inflation pressure must not exceed the maximum infla-
tion 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.
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 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
162 STARTING AND OPERATING

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. 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 an accident. Al-
ways use radial ply tires in sets of four (or six, 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.

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
“Tread Wear Indicators”). Refer to the “Tire and Loading
Information” 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.WARNING!
•DO 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.
•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 an accident.

TIRE PRESSURE MONITOR SYSTEM (TPMS)
Low Tire Indicator
If tire pressure falls below 23 psi (159 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
18 psi (124 kpa), the Low Tire Pressure Telltale will
illuminate, 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.
WARNING!
Do not exceed 55 mph (88 km/h) if the LOW Tire
indicator is activated. Vehicle handling and braking
may be reduced. You could have an accident and be
severely or fatally injured.

TIREFIT Storage
The TIREFIT kit is located in the trunk.
TIREFIT Usage Precautions
NOTE:
•Replace the TIREFIT Sealant Bottle prior to the expi-
ration date (printed on the bottle label) to assure
optimum operation of the system.
•When the TIREFIT Sealant is in a liquid form, clean
water, and a damp cloth will remove the material from
the vehicle or tire and wheel components. Once the
sealant dries, it can easily be peeled off and properly
discarded.
•For optimum performance, make sure the valve stem
on the wheel is free of debris before connecting the
TIREFIT kit.
•You can use the TIREFIT air pump to inflate bicycle
tires. The kit also comes with two needles located in
the Accessory Storage Compartment 8 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 punc-
tures in the tire tread of a tire on this vehicle.
WARNING!
•Do 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.
•Do not use TIREFIT or drive the vehicle under the
following circumstances:
If the cut or puncture in the tire tread is approxi-
mately 0.24 in (6 mm) or larger.
If the tire has any sidewall damage.
(Continued)
WARNING! (Continued)
If the tire has any damage from driving with
extremely low tire pressure.
If the tire has any damage from driving on a flat
tire.
If the wheel has any damage.
If you are unsure of the condition of the tire or the
wheel.
•Keep TIREFIT away from open flame or heat source.
•TIREFIT 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.
•A 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.
