Loading Your Vehicle
n ", ,. , I --- SEE OWNER'S MANUAL FOR ADDITIONAL INFORMATION I U
The Certificatiomire label is found on the rear edge of
the driver's door or in the Incomplete Vehicle Document
in the cab.
The label shows the size of your original tires and the
inflation pressures needed to obtain the gross weight
capacity
of your vehicle. This is called the GVWR
(Gross Vehicle Weight Rating).
The GVWR includes the
weight of the vehicle, all occupants, fuel and cargo.
The Certificationmire label also tells
you the maximum
weights for the front and rear axles, called Gross
Axle
Weight Rating (GAWR). To find out the actual loads on your
front and rear axles,
you need to go to a weigh
station and weigh your vehicle. Your dealer can help
you with this. Be sure to spread out your load equally on
both sides of the centerline.
Never exceed the GVWR for your vehicle, or the
GAWR for either the front or rear axle.
And,
if you do have a heavy load, you should spread
it
out.
I
In the case of a sudden stop or collision, things
carried in the bed
of your truck could shift
forward and come into the passenger area,
injuring you and others.
If you put things in the
bed
of your truck, you should make sure they are
properly secured.
Using heavier suspension components to get added
durability might not change your weight ratings. Ask
your dealer to help you load your vehicle the right way.

Inflation -- Tire Pressure
The Certification/Tire label. which is on the rear edge of
the driver's door, or on the incomplete vehicle document
in the cab, shows the correct inflation pressures for your
tires when they're cold. "Cold" means your vehicle has
been sitting for at least three hours or driven no more
than
I mile (I .6 km).
You can operate some vehicles at reduced inflation
pressures
only when you'll be carrying reduced loads.
On those vehicles, the minimum cold inflation pressures
for a typical reduced load are printed on the Improved
Ride Tire Pressure label located
on the driver's door.
Weigh the vehicle to find the load on each tire and see
the label for the
minimum cold inflation pressures for
that load.

If your vehicle has dual rear wheels and the load range
and tread design for your front tires is the same as your
rear tires. always
use one of the correct rotation patterns
shown here when rotating your tires.
11 If your vehicle has dual rear
Q
wheels and the load range
or tread design for
your
~ front tires is different from
your rear tires, always use
the correct rotation pattern shown here when rotating
your tires.
The dual tires are rotated
as a pair, and the inside rear
tires become the outside rear tires.
When
you install dual wheels, be sure the vent holes in
the inner and outer wheels on each side are lined up.
After the tires have been rotated, adjust the front and rear
inflation pressures as shown on the Certificatiomire
label. Make certain that
all wheel nuts are properly
tightened. See “Wheel
Nut Torque” in the Index.
