Tongue load
Gross Axle Weight Gross Vehicle Weight
OOSH069130L
The tongue load is an important weight
to measure because it affects the
total Gross Vehicle Weight (GVW) of
your vehicle. The trailer tongue should
weigh a maximum of 10% of the total
loaded trailer weight, within the limits
of the maximum trailer tongue load
permissible.
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 moving some
items around in the trailer.
WARNING
Take the following precautions:
[ Never load a trailer with more weight
in the rear than in the front. The front
should be loaded with approximately
60% of the total trailer load; the rear
should be loaded with approximately
40% of the total trailer load.
[ Never exceed the maximum weight
limits of the trailer or trailer towing
equipment. Improper loading can
result in damage to your vehicle and/
or personal injury. Check weights
and loading at a commercial scale or
highway patrol office equipped with
scales.
Information
With increasing altitude the engine
performance decreases. From 1,000 m
above sea level and for every 1,000 m
thereafter 10% of vehicle/trailer weight
(trailer weighter + gross vehicle weight)
must be deducted.

Two labels on your driver’s door sill show
how much weight your vehicle was
designed to carry: the Tire and Loading
Information Label and the Certification

Before loading your vehicle, familiarize
yourself with the following terms for

ratings, from the vehicle’s specifications
and the Certification Label:

when you picked it up from your dealer
plus any aftermarket equipment.

This figure includes all weight added to
the Base Curb Weight, including cargo
and optional equipment.
GAW (Gross Axle Weight)
This is the total weight placed on each
axle (front and rear) - including vehicle
curb weight and all payload.GAWR (Gross Axle Weight Rating)
This is the maximum allowable weight
that can be carried by a single axle (front
or rear). These numbers are shown on
the Certification Label. The total load on
each axle must never exceed its GAWR.
GVW (Gross Vehicle Weight)
This is the Base Curb Weight plus actual
Cargo Weight plus passengers.

This is the maximum allowable weight
of the fully loaded vehicle (including
