2010 JEEP WRANGLER spare tire

WARNING!
Tires and the 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 unmounted 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 (see the paragraph on tread
wear indicators). Refer to the Tire and Loading Informa-
tion 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, han-
dling, and ride of your vehicle. We recommend that you
refer to your original equipment or contact an authorized
tire dealer with any questions you may have on tire
specifications or capability.

STARTING AND OPERATING 403

•Tire Pressure Monitoring Telltale Light
A tire pressure monitoring sensor is located in the spare
wheel if the vehicle is equipped with a matching full size
spare wheel and tire assembly. The matching full size
spare tire can be used in place of any of the four road
tires. A low spare tire will not cause the “Tire Pressure
Monitoring Telltale Light” to illuminate or the chime to
sound. The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster, and an au-
dible chime will be activated when one or more of
the four active road tire pressures are low. Should this
occur, you should stop as soon as possible, check the
inflation pressure of each tire on your vehicle, and inflate
each tire to the vehicle’s recommended cold placard
pressure value. The system will automatically update
and the “Tire Pressure Monitoring Telltale Light” 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.
The “Tire Pressure Monitoring Telltale Light” will flash
on and off for 75 seconds, and will remain on solid when
a system fault is detected. The system fault will also
sound a chime. If the ignition key is cycled, this sequence
will repeat, providing the system fault still exists. A
system fault can occur by any of the following scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the TPM
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel
housings.
4. Using tire chains on the vehicle.

STARTING AND OPERATING 409

5. Using wheels/tires not equipped with TPM sensors.
NOTE:
•If your vehicle is equipped with a matching full-size
spare wheel and tire assembly, it has a tire pressure
monitoring sensor, and can be monitored by the Tire
Pressure Monitoring System (TPMS). In the event that
the matching full-size spare tire is swapped with a low
pressure road tire, the next ignition key cycle will still
show the “Tire Pressure Monitoring Telltale Light” to
be ON, and a chime to sound. Driving the vehicle for
up to 20 minutes above 15 mph (25 km/h) will turn
OFF the “Tire Pressure Monitoring Telltale Light” as
long as none of the road tires are below the low
pressure warning threshold.
•If your vehicle is not equipped with a matching
full-size spare wheel and tire assembly, it does not
have a tire pressure monitoring sensor in the spare tire.
The TPMS will not be able to monitor the tire pressure.If you install the spare tire in place of a road tire that
has a pressure below the low-pressure warning limit,
upon the next ignition key cycle, a chime will sound
and the “Tire Pressure Monitoring Telltale Light” will
turn ON. After driving the vehicle for up to 20 minutes
above 15 mph (25 km/h), the “Tire Pressure Monitor-
ing Telltale Light” will flash on and off for 75 seconds
and then remain on solid. For each subsequent ignition
key cycle, a chime will sound and the “Tire Pressure
Monitoring Telltale Light” will flash on and off for
75 seconds and then remain on solid. Once you repair
or replace the original road tire, and reinstall it on the
vehicle in place of the spare tire, the TPMS will update
automatically and the “Tire Pressure Monitoring Tell-
tale Light” will turn OFF, as long as no tire pressure is
below the low-pressure warning limit in any of the
four active road tires. The vehicle may need to be
driven for up to 20 minutes above 15 mph (25 km/h)
in order for the TPMS to receive this information.
410 STARTING AND OPERATING

WARNING! (Continued)
•Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on
the tow vehicle. Put the tow vehicle automatic
transmission in PARK. With a manual transmis-
sion, shift the transmission into first gear. And
with four-wheel-drive vehicles, make sure the
transfer case is not in N (Neutral). Always, block
or\bchock\b the trailer wheels.
•GCWR must not be exceeded.
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
(Continued)
WARNING! (Continued)
4. Tongue weight rating for the trailer hitch utilized
(This requirement may limit the ability to always
achieve the 10% to 15% range of tongue weight as a
percentage of total trailer weight).
Towing Requirements – Tires

Do not attempt to tow a trailer while using a compact
spare tire.
Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires – General Information” in “Starting and Oper-
ating” for proper tire inflation procedures.
Check the trailer tires for proper tire inflation pres-
sures before trailer usage.

Spare Tire Stowage
To remove the spare tire from the carrier, remove the tire
cover, if equipped, and remove the lug nuts with the lug
wrench turning them counterclockwise.
NOTE:If you have added aftermarket accessories to the
spare tire mounted carrier, it cannot exceed a gross
weight of 50 lbs (23 kg) including the weight of the spare
tire.
Preparations For Jacking
1. Park on a firm, level surface. Avoid ice or slippery
areas.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid being hit when operating the jack
or changing the wheel. 2. Turn on the Hazard Warning flasher.
3. Set the parking brake.
4. Shift the automatic transmission into PARK, or a
manual transmission into REVERSE.
5. Turn the ignition to LOCK.
6. Block both the front and rear of the
wheel diagonally opposite of the jack-
ing position. For example, if changing
the right front tire, block the left rear
wheel.
NOTE: Passengers should not remain in the vehicle
when the vehicle is being jacked.

Jacking Instructions
WARNING!
Carefully follow these tire changing warnings to
help prevent personal injury or damage to your
vehicle:
•Always park on a firm, level surface as far from
the edge of the roadway as possible before raising
the vehicle.
•Block the wheel diagonally opposite the wheel to
be raised.
•Set the parking brake firmly and set an automatic
transmission in PARK; a manual transmission in
REVERSE.
•Never start or run the engine with the vehicle on a
jack.(Continued)
WARNING! (Continued)
•Do not let anyone sit in the vehicle when it is on a
jack.
•Do not get under the vehicle when it is on a jack.
•Only use the jack in the positions indicated and
for lifting this vehicle during a tire change.
•If working on or near a roadway, be extremely
careful of motor traffic.
•To assure that spare tires, flat or inflated, are
securely stowed, spares must be stowed with the
valve stem facing the ground.
•Turn on the Hazard Warning flasher.
444 WHAT TO DO IN EMERGENCIES

1. Remove the spare tire, jack and tools from the stored
location.
2. Loosen (but do not remove) the wheel lug nuts by
turning them to the left one turn while the wheel is still
on the ground.
3. Assemble the jack and jacking tools. Connect the jack
handle driver to the extension, then to the lug wrench.
4. Operate the jack from the front or the rear of the
vehicle. Place the jack under the axle tube, as shown.Do
not raise the vehicle until you are sure the jack is fully
engaged. 5. Raise the vehicle by turning the jack screw to the right.
Raise the vehicle only until the tire just clears the surface
and enough clearance is obtained to install the spare tire.
Minimum tire lift provides maximum stability.
