spare tire Ram 4500 Chassis Cab 2018 User Guide

— Tire Pressure Monitoring System
(TPMS) Warning Light
The warning light switches on and a message
is displayed to indicate that the tire pressure
is lower than the recommended value and/or
that slow pressure loss is occurring. In these
cases, optimal tire duration and fuel con-
sumption may not be guaranteed.
Should one or more tires be in the condition
mentioned above, the display will show the
indications corresponding to each tire in
sequence.
CAUTION!
Do not continue driving with one or more
flat tires as handling may be compro-
mised. Stop the vehicle, avoiding sharp
braking and steering. If a tire puncture
occurs, repair immediately using the dedi-
cated tire repair kit and contact your au-
thorized dealer as soon as possible.
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the vehicle placard or tire inflation pressure la-
bel. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor-
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your tires
as soon as possible, and inflate them to the
proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the
driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.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 se-
quence will continue upon subsequent ve-
hicle start-ups as long as the malfunction
exists. When the malfunction indicator is
illuminated, 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 replace-
ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunc-
tion telltale after replacing one or more tires
or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.

• Signal interference due to electronic de-vices or driving next to facilities emitting
the same radio frequencies as the TPM
sensors.
• Installing aftermarket window tinting that contains materials that may block radio
wave signals.
• Accumulation of snow or ice around the wheels or wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors.
A system fault may occur due to an incorrect
TPM sensor location condition. When a sys-
tem fault occurs due to an incorrect TPM
sensor location, the “Tire Pressure Monitor-
ing Telltale Light” will flash on and off for
75 seconds and then remain on solid. The
system fault will also sound a chime. In
addition, the instrument cluster will display a
“Tire Pressure Temporarily Unavailable”
message in place of the tire pressure display
screen. If the ignition switch is cycled, this
sequence will repeat, providing the system
fault still exists. If the system fault no longer
exists, the “Tire Pressure Monitoring Telltale Light” will no longer flash and the tire pres-
sure display screen will be displayed showing
the tire pressure values the correct locations.
Vehicles With Non Matching Full Size Spare Or
Compact Spare
• The non matching full size spare or com-
pact spare tire does not have a TPM sensor.
Therefore, the TPMS will not monitor the
pressure in the non matching full size spare
or compact spare tire.
• If you install the non matching full size spare or compact spare tire in place of a
road tire that has a pressure below the
low-pressure warning limit, upon the next
ignition switch cycle, the TPM Telltale
Light and a “LOW TIRE” message will re-
main ON and a chime will sound. In addi-
tion, the graphic in the instrument cluster
will still display a pressure value in a differ-
ent color.
• After driving the vehicle for up to 20 min- utes above 15 mph (24 km/h), the TPM
Telltale Light will flash on and off for
75 seconds and then remain on solid. In
addition, the instrument cluster will display a "SERVICE TPM SYSTEM" message for a
minimum of five seconds and then display
dashes (- -) in place of the pressure value.
• For each subsequent ignition switch cycle, a chime will sound, the TPM Telltale Light
will flash on and off for 75 seconds and
then remain on solid, and the instrument
cluster will display a "SERVICE TPM SYS-
TEM" message for a minimum of five sec-
onds and then display dashes (- -) in place
of the pressure value.
• Once you repair or replace the original road tire and reinstall it on the vehicle in place of
the non matching full size spare or compact
spare, the TPMS will update automatically.
In addition, the TPM Telltale Light will turn
OFF and the graphic in the instrument
cluster will display a new pressure value
instead of dashes (- -), 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 (24 km/h) in
order for the TPMS to receive this
information.

Periodic Safety Checks You
Should Make Outside The Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones,
nails, glass, or other objects lodged in the
tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts,
cracks, and bulges. Check the wheel bolts for
tightness. Check the tires (including spare)
for proper cold inflation pressure.

5500 Series
WARNING!
Carefully follow these tire changing warn-
ings 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.
• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the
wheel to be raised.
• Set the parking brake firmly and set the
transmission in PARK.
• Never start or run the engine with the
vehicle on a jack.
• 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. If you need to get under a
raised vehicle, take it to a service center
where it can be raised on a lift.
• Only use the jack in the positions indi-
cated and for lifting this vehicle during a
tire change.
WARNING!
• If working on or near a roadway, beextremely careful of motor traffic.
• To assure that spare tires, flat or in-
flated, are securely stowed, spares must
be stowed with the valve stem facing the
ground.

CAUTION!
Do not attempt to raise the vehicle by
jacking on locations other than those indi-
cated in the Jacking Instructions for this
vehicle.
1. If equipped, remove the spare wheel, jack, and tools from storage.
2. Using the lug wrench, loosen, but do not remove, the lug nuts by turning them
counterclockwise one turn while the
wheel is still on the ground.
3. When changing the front wheel, assemble the jack driver to the jack and connect the
jack driver to the extension tube. Place
the jack under the axle as close to the tire
as possible with the jack driver extending
to the front. Connect the extension tubes
and lug wrench. When changing a rear wheel, assemble
the jack driver to the jack and connect
the jack driver to the extension tubes.
Securely place the jack under the sway
bar bracket (unless both tires are flat on
one side, then place jack under shock
bracket) facing forward in vehicle. Con-
nect the extension tubes and lug wrench.Before raising the wheel off the ground,
make sure that the jack will not damage
surrounding truck parts and adjust the jack
position as required.
NOTE:
If the jack will not lower by turning the
dial (thumbwheel) by hand, it may be
necessary to use the jack driver in order to
lower the jack.

4. By rotating the lug wrench clockwise,raise the vehicle until the wheel just
clears the surface.
WARNING!
Raising the vehicle higher than necessary
can make the vehicle less stable. It could
slip off the jack and hurt someone near it.
Raise the vehicle only enough to remove
the tire.
5. Remove the lug nuts and pull the wheel off. Install the spare wheel and lug nuts
with the cone shaped end of the nuts
toward the wheel on single rear wheel
(SRW) models. On dual rear wheel models
(DRW) the lug nuts are a two-piece assem-
bly with a flat face. Lightly tighten the
nuts. To avoid risk of forcing the vehicle
off the jack, do not fully tighten the nuts
until the vehicle has been lowered.
6. Using the lug wrench, finish tightening the nuts using a crisscross pattern. For
the proper lug nut torque specifications
refer to “Wheel And Tire Torque Specifi-
cations” in “Technical Specifications.” If
in doubt about the correct tightness, have them checked with a torque wrench by an
authorized dealer or at a service station.
WARNING!
A loose tire or jack thrown forward in a
collision or hard stop, could endanger the
occupants of the vehicle. Always stow the
jack parts and the spare tire in the places
provided.
7. Install wheel center cap (if equipped) and remove wheel blocks. Do not install
chrome or aluminum wheel center caps
on the spare wheel. This may result in cap
damage.
8. Lower the jack to its fully closed position. If the jack will not lower by turning the
dial (thumbwheel) by hand, it may be
necessary to use the jack driver in order to
lower the jack. Stow the replaced tire,
jack, and tools as previously described.
9. Adjust the tire pressure when possible.
To Stow The Flat Or Spare —
If Equipped
Refer to Upfitters Body Builders Guide for
information on stowing your spare tire (if
equipped).
Hub Caps/Wheel Covers —
If Equipped
The hub caps must be removed before raising
the vehicle off the ground.
CAUTION!
Use extreme caution when removing the
front and rear center caps. Damage can
occur to the center cap and/or the wheel if
screwdriver type tools are used. A pulling
motion, not a pry off motion, is recom-
mended to remove the caps.
For single rear wheel (SRW) models, use the
flat blade on the end of the lug wrench to pull
the hub cap off. Insert the blade end into the
pull off notch and carefully pull the hub cap
off with a back and forth motion.

TIRES
Tire Safety Information
Tire safety information will cover aspects of
the following information: Tire Markings, Tire
Identification Numbers, Tire Terminology and
Definitions, Tire Pressures, and Tire Loading.
Tire MarkingsNOTE:
• P (Passenger) — Metric tire sizing is basedon U.S. design standards. P-Metric tires
have the letter “P” molded into the sidewall
preceding the size designation. Example:
P215/65R15 95H.
• European — Metric tire sizing is based on European design standards. Tires designed
to this standard have the tire size molded
into the sidewall beginning with the section
width. The letter "P" is absent from this tire
size designation. Example: 215/
65R15 96H.
• LT (Light Truck) — Metric tire sizing is based on U.S. design standards. The size
designation for LT-Metric tires is the same
as for P-Metric tires except for the letters
“LT” that are molded into the sidewall pre-
ceding the size designation. Example:
LT235/85R16.
• Temporary spare tires are designed for tem- porary emergency use only. Temporary high
pressure compact spare tires have the letter
“T” or “S” molded into the sidewall preced-
ing the size designation. Example: T145/
80D18 103M.
