Certification/Tire Label
A vehicle specific Certification/
Tire label is found on the rear
edge of the driver door. The
label shows the size of your
vehicle's original tires and the
inflation pressures needed to
obtain the gross weight capacity
of your vehicle. This is called
Gross Vehicle Weight Rating
(GVWR). The GVWR includes
the weight of the vehicle, all
occupants, fuel, and cargo.
The Certification/Tire 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.
The Certification/Tire label also
contains information about your
Front Axle Reserve Capacity.
And, if you do have a heavy
load, you should spread it out.
Driving and Operating
WARNING
Do not load the vehicle any
heavier than the Gross
Vehicle Weight Rating
(GVWR), or either the
maximum front or rear Gross
Axle Weight Rating (GAWR).
If you do, parts on the vehicle
can break, and it can change
the way the vehicle handles.
These could cause you to lose
control and crash. Also,
overloading can shorten the
life of the vehicle.
Overloading the
vehicle may cause damage.
Repairs would not be covered
by the vehicle warranty. Do
not overload the vehicle.
The label will help you decide
how much cargo and installed
equipment your truck can carry.
