2018 Ram 4500 Chassis Cab tires

CAUTION!
• Then, during the first 500 miles(805 km) that a trailer is towed, do not
drive over 50 mph (80 km/h) and do not
make starts at full throttle. This helps
the engine and other parts of the vehicle
wear in at the heavier loads.
Perform the maintenance listed in the
“Scheduled Servicing”. Refer to “Scheduled
Servicing” in “Servicing And Maintenance”
for the proper maintenance intervals. When
towing a trailer, never exceed the GAWR or
GCWR ratings.
WARNING!
Improper towing can lead to a collision.
Follow these guidelines to make your
trailer towing as safe as possible:
• Make certain that the load is secured in the trailer and will not shift during travel.
When trailering cargo that is not fully
secured, dynamic load shifts can occur
that may be difficult for the driver to
WARNING!
control. You could lose control of your
vehicle and have a collision.
• When hauling cargo or towing a trailer,
do not overload your vehicle or trailer.
Overloading can cause a loss of control,
poor performance or damage to brakes,
axle, engine, transmission, steering,
suspension, chassis structure or tires.
• Safety chains must always be used be-
tween your vehicle and trailer. Always
connect the chains to the hook retainers
of the vehicle hitch. Cross the chains
under the trailer tongue and allow
enough slack for turning corners.
• Vehicles with trailers should not be
parked on a grade. When parking, apply
the parking brake on the tow vehicle. Put
the tow vehicle transmission in PARK.
For four-wheel drive vehicles, make sure
the transfer case is not in NEUTRAL.
Always, block or "chock" the trailer
wheels.
• GCWR must not be exceeded.
WARNING!
• 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
4. Tongue weight rating for the trailer hitch utilized.
Towing Requirements — Trailer Brakes
•Do notinterconnect the hydraulic brake
system or vacuum system of your vehicle
with that of the trailer. This could cause
inadequate braking and possible personal
injury.
• An electronically actuated trailer brake controller is required when towing a trailer
with electronically actuated brakes. When
towing a trailer equipped with a hydraulic
surge actuated brake system, an electronic
brake controller is not required.

GAIN Adjustment Buttons (+/-)
Pushing these buttons will adjust the brake
control power output to the trailer brakes in
0.5 increments. The GAIN setting can be
increased to a maximum of 10 or decreased
to a minimum of 0 (no trailer braking).
GAIN
The GAIN setting is used to set the trailer
brake control for the specific towing condi-
tion and should be changed as towing condi-
tions change. Changes to towing conditions
include trailer load, vehicle load, road condi-
tions and weather.
Adjusting GAIN
NOTE:
This should only be performed in a traffic free
environment at speeds of approximately 20–
25 mph (30–40 km/h).
1. Make sure the trailer brakes are in goodworking condition, functioning normally
and properly adjusted. See your trailer
dealer if necessary. 2. Hook up the trailer and make the electri-
cal connections according to the trailer
manufacturer's instructions.
3. When a trailer with electric/EOH brakes is plugged in, the trailer connected message
should appear in the instrument cluster
display (if the connection is not recog-
nized by the ITBM, braking functions will
not be available), the GAIN setting will
illuminate and the correct type of trailer
must be selected from the instrument
cluster display options.
4. Push the UP or DOWN button on the steering wheel until “TRAILER TOW” ap-
pears on the screen.
5. Push the RIGHT arrow on the steering wheel to enter “TRAILER TOW”.
6. Push the UP or DOWN buttons until the Trailer Brake Type appears on the screen. 7. Push the RIGHT arrow and then push the
UP or DOWN buttons until the proper
Trailer Brake Type appears on the screen.
8. In a traffic-free environment, tow the trailer on a dry, level surface at a speed of
20–25 mph (30–40 km/h) and squeeze
the manual brake control lever
completely.
9. If the trailer wheels lockup (indicated by squealing tires), reduce the GAIN setting;
if the trailer wheels turn freely, increase
the GAIN setting.
Repeat steps 8 and 9 until the GAIN setting
is at a point just below trailer wheel lockup. If
towing a heavier trailer, trailer wheel lockup
may not be attainable even with the maxi-
mum GAIN setting of 10.

CAUTION!
• When installing the power distributioncenter cover, it is important to ensure
the cover is properly positioned and fully
latched. Failure to do so may allow water
to get into the power distribution center
and possibly result in an electrical sys-
tem failure.
• When replacing a blown fuse, it is impor-
tant to use only a fuse having the correct
amperage rating. The use of a fuse with
a rating other than indicated may result
in a dangerous electrical system over-
load. If a properly rated fuse continues
to blow, it indicates a problem in the
circuit that must be corrected.
JACKING AND TIRE CHANGING
WARNING!
• Do not attempt to change a tire on theside of the vehicle close to moving traf-
fic. Pull far enough off the road to avoid
the danger of being hit when operating
the jack or changing the wheel.
• Being under a jacked-up vehicle is dan-
gerous. The vehicle could slip off the
jack and fall on you. You could be
crushed. Never put any part of your body
under a vehicle that 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.
• Never start or run the engine while the
vehicle is on a jack.
• The jack is designed to be used as a tool
for changing tires only. The jack should
not be used to lift the vehicle for service
purposes. The vehicle should be jacked
on a firm level surface only. Avoid ice or
slippery areas.
4500/5500 Models
These vehicles do not come equipped with a
jack.
NOTE:
Jacking and tire changing on 4500/
5500 models should be performed by an
authorized dealer, or knowledgeable service
personnel with the appropriate heavy duty
equipment, like a tire service company.
Preparations For Jacking
1. Park the vehicle 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. Place the gear selector into PARK. On four-wheel drive vehicles, shift the trans-
fer case to the 4L position.
3. Turn on the Hazard Warning flasher.

4. Apply the parking brake.
5. Turn the ignition OFF.
6. Block both the front and rear of the wheeldiagonally opposite the jacking position.
For example, if the right front wheel is
being changed, block the left rear wheel.
NOTE:
Passengers should not remain in the vehicle
when the vehicle is being jacked.Jacking Instructions 4500 And
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.

6. Move the gear selector to the NEUTRALposition.
7. The vehicle may then be started in NEUTRAL.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand,
or snow, it can often be moved using a rock-
ing motion. Turn the steering wheel right and
left to clear the area around the front wheels.
Next, shift back and forth between DRIVE
and REVERSE (with automatic transmission)
or SECOND GEAR and REVERSE (with
manual transmission) while gently pressing
the accelerator. Use the least amount of ac-
celerator pedal pressure that will maintain
the rocking motion, without spinning the
wheels or racing the engine. NOTE:
Push the "ESC Off" switch, to place the Elec-
tronic Stability Control (ESC) system in "Par-
tial Off" mode, before rocking the vehicle.
Refer to “Electronic Brake Control System”
in “Safety” in the Owner’s Manual at
www.mopar.com/en-us/care/owners-manual.html
(U.S. Residents) or www.owners.mopar.ca
(Canadian Residents) for further information.
Once the vehicle has been freed, push the
"ESC Off" switch again to restore "ESC On"
mode.
WARNING!
Fast spinning tires can be dangerous.
Forces generated 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
vehicle's wheels faster than 30 mph
(48 km/h) or for longer than 30 seconds
continuously without stopping when you
are stuck and do not let anyone near a
spinning wheel, no matter what the speed.
CAUTION!
• Racing the engine or spinning the
wheels may lead to transmission over-
heating and failure. Allow the engine to
idle with the transmission in NEUTRAL
for at least one minute after every five
rocking-motion cycles. This will mini-
mize overheating and reduce the risk of
clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
• When “rocking” a stuck vehicle by shift-
ing between DRIVE/SECOND GEAR and
REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain
damage may result.
• Revving the engine or spinning the
wheels too fast may lead to transmission
overheating and failure. It can also dam-
age the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).
