Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important
weight to measure because it affects the total
or gross weight of your vehicle. The Gross Vehicle
Weight (GVW) includes the curb weight of the
vehicle, any cargo you may carry in it, and
the people who will be riding in the vehicle. If you
have a lot of options, passengers, or cargo in
the vehicle, it will reduce the tongue weight your
vehicle can carry, which will also reduce the trailer
weight your vehicle can tow. And if you will tow
a trailer, you must add the tongue load to the GVW
because your vehicle will be carrying that weight,
too. See Loading Your Vehicle on page 321
for more information about your vehicle’s maximum
load capacity.
If you are using a weight-carrying or a
weight-distributing hitch, the trailer tongue
weight (A) should be 10 percent to 15 percent of
the total loaded trailer weight (B). Do not exceed
the maximum allowable tongue weight for your
vehicle.
After you have loaded your trailer, weigh the trailer
and then the tongue, separately, to see if the
weights are proper. If they are not, you may be
able to get them right simply by moving some
items around in the trailer.
