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 passen-
gers, 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 compo-
nents in the system with the lowest load
carrying capacity (axle, springs, tires or
wheels). Heavier axles or suspension compo-
nents sometimes specified by purchasers for
increased durability do not necessarily
increase the vehicle's GVWR.
Tire Size
The tire size on the Vehicle Certification 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.
Inflation Pressure
This is the cold tire inflation pressure for your
vehicle for all loading conditions up to full
GAWR.
Curb Weight
The curb weight of a vehicle is defined as the
total weight of the vehicle with all fluids,
including vehicle fuel, at full capacity condi-
tions, and with no occupants or cargo loaded
into the vehicle. The front and rear curb weight
values are determined by weighing your
vehicle on a commercial scale before any
occupants or cargo are added.
Loading
The actual total weight and the weight of the
front and rear of your vehicle at the ground can
best be determined by weighing it when it is
loaded and ready for operation.
The entire vehicle should first be weighed on a
commercial scale to ensure that the GVWR
has not been exceeded. The weight on the
front and rear of the vehicle should then be
determined separately to be sure that the load
is properly distributed over the front and rear
axle. Weighing the vehicle may show that the
GAWR of either the front or rear axles has
been exceeded but the total load is within the
specified GVWR. If so, weight must be shifted
from front to rear or rear to front as appro-
priate until the specified weight limitations are
met. Store the heavier items down low and be
sure that the weight is distributed equally.
Stow all loose items securely before driving.
Improper weight distributions can have an
adverse effect on the way your vehicle steers
and handles and the way the brakes operate.
CAUTION!
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.
