CAUTION! (Continued)
²Observe the tire chain manufacturer's instructions
on method of installation, operating speed, and
conditions for usage. Always use the lower sug-
gested 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 your
truck.
NOTE:The use of class ªSº chains is permitted on your
vehicle with P245/70R17 tires.
CAUTION!
Do not use tire chains on 4x4 trucks equipped with
tires other than P245/70R17 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 your vehicle.
There may not be adequate clearance for the chains
and you are risking structural or body damage to
your vehicle.
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 tend to develop irregular wear pat-
terns. 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 main-
tain mud, snow and wet traction levels, and contribute to
a smooth, quiet ride.Follow the recommended tire rotation frequency for your
type of driving found in the ªMaintenance Schedulesº
section of this manual. More frequent rotation is permis-
sible if desired. The reasons for any rapid or unusual
wear should be corrected prior to rotation being per-
formed.

For example, your vehicle has a recommended cold
(parked for more than three hours) placard pressure of 33
psi (227 kPa). If the ambient temperature is 68ÉF (20ÉC)
and the measured tire pressure is 28 psi (193 kPa), a
temperature drop to 20ÉF (-7ÉC) will decrease the tire
pressure to approximately 24 psi (165 kPa). This tire
pressure is sufficiently low enough to turn on the TPMS
light. Driving the vehicle may cause the tire pressure to
rise to approximately 28 psi (193 kPa), but the TPMS light
will still be ON. In this situation, the TPMS light will turn
off only after the tires have been inflated to the vehicle's
recommended cold placard 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 equip-
ment that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Do not
use aftermarket tire sealants or balance beads if your
vehicle is equipped with a TPMS, as damage to the
sensors may result.
CAUTION!
After inspecting or adjusting the tire pressure always
reinstall the valve stem cap. This will prevent mois-
ture and dirt from entering the valve stem, which
could damage the tire pressure monitoring sensor.

WARNING!
Do not load your vehicle any heavier than the GVWR
or the maximum front and rear GAWR. If you do,
parts on your vehicle can break, or it can change the
way your vehicle handles. This could cause you to
lose control. Also, overloading can shorten the life of
your vehicle.
TRAILER TOWING
In this section you will find safety tips and information
on limits to the type of towing you can reasonably do
with your vehicle. Before towing a trailer carefully re-
view this information to tow your load as efficiently and
safely as possible.
To maintain warranty coverage, follow the requirements
and recommendations in this manual concerning ve-
hicles used for trailer towing.
Common Towing Definitions
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do not
exceed the GVWR.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or tem-
porary) loaded in or on the trailer in its9loaded and
ready for operation9condition. The recommended way to
measure GTW is to put your fully loaded trailer on a
vehicle scale. The entire weight of the trailer must be
supported by the scale.

Never exceed the maximum tongue weight stamped on
your bumper or trailer hitch.
Consider the following items when computing the
weight on the rear axle of the vehicle:
²The tongue weight of the trailer.
²The weight of any other type of cargo or equipment
put in or on your vehicle.
²The weight of the driver and all passengers.
NOTE:Remember that everything put into or on the
trailer adds to the load on your vehicle. Also, additional
factory-installed options, or dealer-installed options,
must be considered as part of the total load on your
vehicle. Refer to ªTire and Loading Information Placardº
under ªTire Safety Informationº in Section 5.
Towing Requirements
To promote proper break-in of your new vehicle drivetrain
components the following guidelines are recommended:
CAUTION!
²Avoid towing a trailer for the first 500 miles (805
km) of vehicle operation. Doing so may damage
your vehicle.
²During the first 500 miles (805 km) of trailer
towing, limit your speed to 50 mph (80 km/h).
