The weight that the tongue of a fully
loaded trailer puts on the hitch
shouldbe5to10percentofthetotal
trailer weight for boat trailers, and 8
to 15 percent of total trailer weight
for all other trailers. See page for
limits for your towing situation.
Too much tongue load reduces front-
tire traction and steering control.
Too little tongue load can make the
trailer unstable and cause it to sway.
Park the vehicle on level ground.
Measure and record the distance
from the ground to the bottom of
the trailer hitch.
Connect the fully loaded trailer to
the hitch.
Measure again from the ground to
the same spot on the bottom of the
hitch.
Subtract the second measurement
from the first measurement. Refer
to Fig. 1.

you have too much tongue load
at the rear. Move or remove
cargo from the trailer and the
vehicle, and measure again.
If the estimated trailer weight and
tongue load do not exceed the limits,
drive your trailer to a public scale
fully loaded with all occupants and
cargo you plan to take on the road.
