Trailer weight
How heavy can a trailer safely be? It
should never weigh more than the
maximum trailer weight with trailer
brakes. But even that can be too
heavy.
It depends on how you plan to use
your trailer. For example, speed, alti-
tude, road grades, outside tempera-
ture and how often your vehicle is
used to pull a trailer are all important.
The ideal trailer weight can also
depend on any special equipment
that you have on your vehicle.
Tongue load
The tongue load of any trailer is an
important weight to measure
because it affects the total gross
vehicle weight (GVW) of your vehi-
cle. This weight includes the curb
weight of the vehicle, any cargo you
may carry in it, and the people who
will be riding in the vehicle. And if you
will tow a trailer, you must add the
tongue load to the GVW because
your vehicle will also be carrying that
weight.
The trailer tongue should weigh a
maximum of 10% of the total loaded
trailer weight, within the limits of the
maximum permissible trailer tongue
load. After you've loaded your trailer,
weigh the trailer and then the tongue,
separately, to see if the weights are
proper. If they aren’t, you may be
able to correct them simply by mov-
ing some items around in the trailer.
