If your trailer has a GVWR of 10,000 pounds or less, there is a vehicle placard in the
same location as the certification label described above. This placard provides tire and
loading information. In addition, this placard will show a statement regarding maximum
cargo capacity. Cargo can be added to the trailer, up to the maximum weight specified on
the placard. The combined weight of the cargo is provided as a single number. In any
case, remember: the total weight of a fully loaded trailer can not exceed the stated
GVWR.
When loading your cargo, be sure it is distributed evenly to prevent overloading front to
back and side to side. Heavy items should be placed low and as close to the axle
positions as reasonable. Too many items on one side may overload a tire. The best way
to know the actual weight of the vehicle is to weigh it at a public scale. Talk to your
dealer to discuss the weighing methods needed to capture the various weights related to
the trailer. This would include the weight empty or unloaded, weights per axle, wheel,
hitch or kingpin, and total weight.
Excessive loads and/or under inflation cause tire overloading and, as a result, abnormal
tire flexing occurs. This situation can generate an excessive amount of heat within the
tire. Excessive heat may lead to tire failure. It is the air pressure that enables a tire to
support the load, so proper inflation is critical. The proper air pressure may be found on
the certification/VIN label and/or on the Tire Placard. This value should never exceed
the maximum cold inflation pressure stamped on the tire.
Trailers Over 10,000 Pounds GVWR
(Note: These trailers are not required to have a tire information placard on the vehicle)
Determine the empty weight of your trailer by weighing the trailer using a public scale or
other means. This step does not have to be repeated.
Locate the GVWR (Gross Vehicle Weight Rating) of the trailer on your trailer’s VIN
(Certification) label. Subtract the empty weight of your trailer from the GVWR stated on
the VIN label. That weight is the maximum available cargo capacity of the trailer and
may not be safely exceeded.
CHECKING TONGUE WEIGHT
Checking the Trailer Before and During Each Tow. Put the entire trailer on a scale and
weigh the total loaded trailer. Then position the tongue on the scale and determine the
