2010 DODGE VIPER tires

SNOW TIRES
There are no snow tires that are compatible with the
wheels on this vehicle.
TIRE ROTATION RECOMMENDATIONS
Tires on the front and rear axles of vehicles operate at
different loads and perform different steering, driving,
and braking functions. For these reasons, they wear at
unequal rates.
These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on all season type
tires. Rotation will increase tread life, help to maintain
mud, snow, and wet traction levels, and contribute to a
smooth, quiet ride.Refer to “Maintenance Schedule” for the proper mainte-
nance interval. Remember, more frequent rotation is
permissible if desired. Also, correct for anything causing
rapid or unusual wear prior to performing the tire
rotation.
NOTE:
Each wheel on your vehicle contains a tire
pressure sensor. The Tire Pressure Monitor System
(TPMS) learns the location of each sensor though system
programming. Although not required, 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.
Rotate the tires “side-to-side” as shown in the diagram.
178 STARTING AND OPERATING

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.
TPMS Malfunction Warning
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale will
flash for approximately one minute and then remain
continuously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as the mal-
function exists. When the malfunction indicator is illumi-
nated, the system may not be able to detect or signal low
tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons,
including the installation of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS from
functioning properly. Always check the TPMS malfunc-
tion telltale after replacing one or more tires or wheels on
180 STARTING AND OPERATING

your vehicle to ensure that the replacement or alternate
tires and wheels allow the TPMS to continue to function
properly.
FUEL REQUIREMENTS
8.4L Engine
The 8.4L engine is designed to meet all
emissions regulations and provide excel-
lent fuel economy and performance when
using high-quality premium unleaded
gasoline with an octane rating of 91 or
higher.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required. Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of “premium” gasoline
before considering service for the vehicle.
Over 40 automobile manufacturers around the world
have issued and endorsed consistent gasoline specifica-
tions (the World Wide Fuel Charter, WWFC) which
define fuel properties necessary to deliver enhanced
emissions, engine performance, and durability for your
vehicle. The manufacturer recommends the use of gaso-
lines that meet the WWFC specifications if they are
available.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gasoline.”
Reformulated gasolines contain oxygenates, and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.

TIREFIT Usage Precautions
•
Replace the TIREFIT Sealant Bottle (1) and Sealant
Hose (6) prior to the expiration date (printed on the
bottle label) to assure optimum operation of the sys-
tem. Refer to “Sealing a Tire with TIREFIT” section (F)
“Sealant Bottle and Hose Replacement”.
•The Sealant Bottle (1) and Sealant Hose (6) is a one tire
application use. After each use, always immediately
replace these components at an authorized dealer.
•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 (located on the
bottom of the air pump) for inflating sport balls, rafts,
or like inflatable items. However, use only the Air
Pump Hose (7) and make sure the Mode Select Knob
(5) is in the Air Mode when inflating such items to
avoid injecting sealant into them. The TIREFIT Sealant
is only intended to seal punctures less than
14” (6mm)
diameter in the tread of your vehicle.
•Do not lift or carry TIREFIT kit by hoses.
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.

194 WHAT TO DO IN EMERGENCIES

CAUTION! (Continued)
•Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure.
It can also damage the tires. Do not spin the
wheels above 30 mph (48 km/h) while in gear (no
transmission shifting occurring).
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause damage, or
even failure, of the axle and tires. A tire could
explode and injure someone. Do not spin your vehi-
cle’s wheels faster than 30 mph (48 km/h) or for
longer than 30 seconds continuously without stop-
ping when you are stuck. And do not let anyone near
a spinning wheel, no matter what the speed.
TOWING A DISABLED VEHICLE
Do not tow with sling-type equipment. Only use flatbed
equipment. Always comply with applicable state or local
towing ordinances.
CAUTION!
Towing with equipment other than flatbed types may
damage your vehicle.
206 WHAT TO DO IN EMERGENCIES

•Fill the fuel tank. This will prevent water condensation
inside the tank. If you plan to store your vehicle more
than two months, add an anti-oxidant fuel stabilizer to
the fuel tank.
•Change the oil to remove any corrosive combustion
related acids in the crankcase.
•Check that the radiator coolant level of protection is to
at least -20°F (-29°C).
•Make sure that all tires are inflated to the optimum
pressure.
•Wash and wax the vehicle to protect the finish.
•Store the vehicle in a dry, well-ventilated location.
•Move the wiper blades away from the windshield.
•Block the wheels. Do not apply the parking brake.
•Cut blocks of plywood about the same size of the tires.
Cover each block with indoor/outdoor carpeting and
place them between the tires and concrete. This will
prevent tire flat spotting.
•For long-term storage, remove the tires and put the
vehicle up on blocks. Stack the tires on plywood and
cover with a tarp to prevent flat spotting.
•If the vehicle will be subjected to freezing tempera-
tures, either remove the battery and store it in a dry,
well ventilated area or connect a trickle charger
(1.5 Amp) with automatic shutdown / overcharge
protection to the battery. However, do not leave the
trickle charger hooked up to the battery without being
plugged in to a 110 Volt AC outlet, as this will result in
further drain on the vehicle’s battery. If the vehicle is
not going to be driven in the next three weeks, perform
the battery recharge procedure in the Service Manual.
Then, either disconnect the battery at the negative
