● A recommended tongue weight varies in accordance with the types
of trailers or towing as described below.
● To ensure the recommended values shown below, the trailer must

(Tongue weight /Gross trailer weight x 100 = 9% to 11%)
Gross trailer weight
Tongue weight
If using a weight distributing hitch when towing, return the front
axle to the same weight as before the trailer connection.
If front axle weight cannot be measured directly, measure the
front fender height above the front axle before connection. Adjust
weight distributing hitch torque until front fender is returned to the
same height as before connection.
The gross trailer weight, gross axle weight and tongue weight
can be measured with platform scales found at a highway weigh-
ing station, building supply company, trucking company, junk
yard, etc.
