WARNING!
•Do not use a tire, wheel size or rating other than that
specified for your vehicle. Some combinations of unap-
proved tires and wheels may change suspension dimen-
sions and performance characteristics, resulting in changes
to steering, handling, and braking of your vehicle. This can
cause unpredictable handling and stress to steering and
suspension components. You could lose control and have
an accident resulting in serious injury or death. Use only
the tire and wheel sizes with load ratings approved for your
vehicle.
•Never use a tire with a smaller load index or capacity, other
than what was originally equipped on your vehicle. Using
a tire with a smaller load index could result in tire over-
loading and failure. You could lose control and have an
accident.
•Failure to equip your vehicle with tires having adequate
speed capability can result in sudden tire failure and loss of
vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
Alignment And Balance
Poor suspension alignment may result in:
•Fast tire wear.
•Uneven tire wear, such as feathering and one-sided
wear.
•Vehicle pull to right or left.
Tires may also cause the vehicle to pull to the left or right.
Alignment will not correct this condition. See your dealer
for proper diagnosis.
308 STARTING AND OPERATING
Improper alignment will not cause vehicle vibration.
Vibration may be a result of tire and wheel out-of-
balance. Proper balancing will reduce vibration and
avoid tire cupping and spotty wear.
SUPPLEMENTAL TIRE PRESSURE INFORMATION
– IF EQUIPPED
A light load vehicle condition is defined as two passen-
gers {150 lbs (68 kg) each} plus 200 lbs (91kg) of cargo.
Cold tire inflation pressures for a lightly loaded vehicle
will be found on the face of the driver’s door.
TIRE CHAINS
Use “Class U” chains on 2500/3500 Ram Trucks, or other
traction aids that meet SAE Type “U” specifications.
NOTE:Chains must be the proper size for the vehicle,
as recommended by the chain manufacturer.
CAUTION!
To avoid damage to your vehicle, tires or chains, observe the
following precautions:
•Because of limited chain clearance between tires and other
suspension components, it is important that only chains in
good condition are used. Broken chains can cause serious
vehicle damage. Stop the vehicle immediately if noise occurs
that could suggest chain breakage. Remove the damaged parts
of the chain before further use.
•Install chains as tightly as possible and then retighten after
driving about 1/2 mile (0.8 km).
•Do not exceed 45 mph (72 km/h).
•Drive cautiously and avoid severe turns and large bumps,
especially with a loaded vehicle.
•Do not install tire chains on front wheels of 4x2 vehicles.
•Do not drive for a prolonged period on dry pavement.
•Observe the tire chain manufacturer’s instructions on method
of installation, operating speed, and conditions for usage.
Always use the lower suggested operating speed of the chain
manufacturer if different than the speed recommended by the
manufacturer.

These cautions apply to all chain traction devices, includ-
ing link and cable (radial) chains.
Tire chain use is permitted only on the rear tires of Ram
4X2 trucks.
NOTE:The use of class “U” chains is permitted on the
front and rear of 4X4, 2500 Ram Trucks with LT245/
70R17E tires.
NOTE:The use of class “U” chains is permitted on the
front and rear of 4X4, 3500 Ram Trucks with Dual Rear
Wheels and LT235/80R17E tires.
NOTE:On 4X2 2500/3500 Ram Trucks, class “U” snow
chains are permitted on the rear wheels only of vehicles
equipped with LT245/70R17, LT265/70R17, and LT235/
80R17 size tires.
NOTE:On 4X4 2500/3500 Single Rear Wheel (SRW)
Ram Trucks, class “U” snow chains are permitted on the
rear wheels only of vehicles equipped with LT265/70R17.CAUTION!
Do not use tire chains on 4x4 Ram trucks equipped
with P265/70R17, LT275/70R17 tires. There may not
be adequate clearance for the chains and you are
risking structural or body damage to your vehicle.
Do not use tire chains on the 4X2 front wheels of
2500/3500 SRW (Single Rear Wheels) equipped with
LT245/70R17, LT265/70R17 tires or 4X4 front tires of
Ram Trucks equipped with LT265/70R17tires. There
may not be adequate clearance for the chains and
you are risking structural or body damage to your
vehicle.
310 STARTING AND OPERATING
SNOW TIRES
Snow tires should be of the same size and type construc-
tion as the front tires. Consult the manufacturer of the
snow tire to determine any maximum vehicle speed
requirement associated with the tire. These tires should
always be operated at the vehicle maximum capacity
inflation pressures under any load condition.
While studded tires improve performance on ice, skid
and traction capability on wet or dry surfaces may be
poorer than that of non-studded tires. Some states pro-
hibit studded tires; therefore, local laws should be
checked before using these tire types.
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, and develop irregular wear patterns.
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 On/Off Road
type tires. Rotation will increase tread life, help to main-
tain mud, snow, and wet traction levels, and contribute to
a smooth, quiet ride.

Rating (GAWR) front and rear, and Vehicle Identification
Number (VIN). A Month-Day-Hour (MDH) number is
included on this label and indicates the Month, Day and
Hour of manufacture. The bar code that appears on the
bottom of the label is your Vehicle Identification Number
(VIN).
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of your vehicle
including driver, passengers, vehicle, options and cargo.
The label also specifies maximum capacities of front and
rear axle systems (GAWR). Total load must be limited so
GVWR and front and rear GAWR are not exceeded.
Payload
The payload of a vehicle is defined as the allowable load
weight a truck can carry, including the weight of the
driver, all passengers, options and cargo.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles or suspension
components sometimes specified by purchasers for in-
creased durability does not necessarily increase the vehi-
cle’s GVWR.
Tire Size
The tire size on the Label represents the actual tire size on
your vehicle. Replacement tires must be equal to the load
capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.

mended torque. Tighten the nuts to final torque in
increments. Progress around the bolt circle, tightening
the nut opposite to the nut just previously tightened until
final torque is achieved. Recommended torques are

To Stow The Flat Or Spare
Turn the wheel so that the valve stem is down. Slide the
wheel retainer through the center of the wheel and
position it properly across the wheel opening.
For convenience in checking the spare tire inflation, stow
with the valve stem toward the rear of the vehicle.Attach the wheel wrench to the extension tube. Rotate the
winch mechanism until the wheel is drawn into place
against the underside of the vehicle. Continue to rotate
until you feel the winch mechanism slip or click 3 or 4
times. It cannot be overtightened. Push against the tire
several times to be sure it is firmly in place.
HOISTING
A conventional floor jack may be used at the jacking
locations, refer to the graphics that show jacking loca-
tions. However, a floor jack or frame hoist must never be
used on any other parts or the underbody.
CAUTION!
Never use a floor jack directly under the differential
housing of a loaded truck or damage to your vehicle
may result.
