Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important weight
to measure because it affects the total gross weight of
the vehicle. The Gross Vehicle Weight (GVW) includes
the curb weight of the vehicle, any cargo carried in it,
and the people who will be riding in the vehicle. If there
are a lot of options, equipment, passengers or cargo
in the vehicle, it will reduce the tongue weight the
vehicle can carry, which will also reduce the trailer
weight the vehicle can tow. If towing a trailer, the tongue
load must be added to the GVW because the vehicle
will be carrying that weight, too. See Loading the
Vehicle on page 5‑18 for more information about the
vehicle's maximum load capacity.
Using a weight-carrying hitch, the trailer tongue (A)
should weigh 10 to 15 percent of the total loaded trailer
weight (B).
After loading the trailer, weigh the trailer and then the
tongue, separately, to see if the weights are proper.
If they are not, adjustments might be made by moving
some items around in the trailer.
Total Weight on the Vehicle's Tires
Be sure the vehicle's tires are inflated to the upper
limit for cold tires. These numbers can be found on
the Certification/Tire label. See Loading the Vehicle on
page 5‑18. Make sure not to go over the GVW limit for
the vehicle, including the weight of the trailer tongue.
