● 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
be loaded by referring to the following instructions.
• Tongue Weight
The gross trailer weight should be distributed so that the tongue
weight is 9% to 11%. (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 th e 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
weighing station, building supply company, trucking company,
junk yard, etc.
