tire size CHRYSLER TOWN AND COUNTRY 2010 5.G User Guide

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).
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 intervals. More frequent rotation is permissible if
desired. The reasons for any rapid or unusual wear
should be corrected prior to rotation being performed.

STARTING AND OPERATING 369

The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above recommended
cold tire placard pressure. Once the low tire pressure
warning has been illuminated, the tire pressure must be
increased to the recommended cold tire placard pressure
in order for the “TPMS Warning Lamp” to be turned off.
The system will automatically update and the “TPMS
Warning Lamp” will extinguish once the updated tire
pressures have been received. The vehicle may need to be
driven for up to 20 minutes above 15 mph (25 km/h) to
receive this information.
For example, your vehicle may have a recommended
cold (parked for more than three hours) tire pressure of
35 psi (241 kPa). If the ambient temperature is 68°F (20°C)
and the measured tire pressure is 30 psi (207 kPa), a
temperature drop to 20°F (-7°C) will decrease the tire
pressure to approximately 26 psi (179 kPa). This tire
pressure is sufficiently low enough to turn on the “TPMSWarning Light.” Driving the vehicle may cause the tire
pressure to rise to approximately 30 psi (207 kPa), but the
“TPMS Warning Light” will still be on. In this situation,
the “TPMS Warning Light” will turn off only after the
tires have been inflated to the vehicle’s recommended
cold tire pressure value.
CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures have
been established for the tire size equipped on your
vehicle. Undesirable system 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 dam-
age. Do not use aftermarket sealants or balance
beads if your vehicle is equipped with a TPMS, as
damage to the sensors may result.

Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, and cargo. The total
load must be limited so that you do not exceed the
GVWR.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR.
WARNING!
Because the front wheels drive and steer the vehicle,
it is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition
can result if either rating is exceeded. You could lose
control of the vehicle and have an accident.
Tire Size
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires
must be equal to the load capacity of this tire size.
390 STARTING AND OPERATING

Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle, for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Overloading
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide satisfactory
service as long as you do not exceed the GVWR and front
and rear GAWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to ensure that
it is not over the GVWR.
Figure out the weight on the front and rear of the vehicle
separately. It is important that you distribute the load
evenly over the front and rear axles.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier axles or suspension
components do not necessarily increase the vehicle’s
GVWR.

10. Lower the vehicle by turning the jack screw to the
left.
11. Finish tightening the lug nuts. Push down on the
wrench while tightening for increased leverage. Alternate
lug nuts until each nut has been tightened twice. The
correct wheel nut tightness is 95 ft lbs (130 N·m). If in
doubt about the correct tightness, have them checked
with a torque wrench by your authorized dealer or at a
service station.
12. Lower the jack to its fully-closed position.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided. Have the deflated (flat) tire
repaired or replaced immediately.13. Place the deflated (flat) tire and compact spare tire
cover assembly. in the rear cargo area.
Do not stow the
deflated tire in the spare tire location. Have the full-
sized tire repaired or replaced, as soon as possible.
14. Stow the cable and wheel spacer before driving the
vehicle. Reassemble the winch handle extensions to form
a “T” and fit the winch “T” handle over the drive nut.
Rotate the nut to the right until the winch mechanism
clicks at least three times.
15. Stow the jack, jack handle and winch handle tools.
16. Check the compact spare tire pressure as soon as
possible. Correct the tire pressure, as required.Wheel Nuts
All wheel nuts should be tightened occasionally, to
eliminate the possibility of wheel studs being sheared or
the bolt holes in the wheels becoming elongated. This is
especially important during the first few hundred miles

WHAT TO DO IN EMERGENCIES 423

CAUTION!
The winch mechanism is designed specifically to
stow a compact spare tire only. Do not attempt to use
the winch to stow the full size flat tire, or any other
full-size tire. Vehicle damage may result.
JUMP-STARTING PROCEDURE
If your vehicle has a discharged battery it can be jump-
started using a set of jumper cables and a battery in
another vehicle or by using a portable battery booster
pack. Jump-starting can be dangerous if done improperly
so please follow the procedures in this section carefully.
NOTE:When using a portable battery booster pack
follow the manufacturer ’s operating instructions and
precautions.
CAUTION!
Do not use a portable battery booster pack or any
other booster source with a system voltage greater
than 12 Volts or damage to the battery, starter motor,
alternator or electrical system may occur.
WARNING!
Do not attempt jump-starting if the battery is frozen.
It could rupture or explode and cause personal injury.
