GROSS COMBINED WEIGHT (GCW)
The Gross Combined Weight (GCW) is the total weight of the tow vehicle with all
passengers, cargo, and fuel, plus the total weight of the trailer and all its cargo.
To determine the GCW, simply weigh your vehicle when fully loaded and ready to tow, and
add in the weight of the loaded trailer.
The GCW you come up with must not exceed the Gross Combined Weight Rating
(GCWR) for your vehicle. See the SPECIFICATIONS section of this guide or refer to your
vehicle owner’s manual to view the GCWR listed for your vehicle.

TRAILER TONGUE/KING PIN LOAD
The amount of weight pressing down on the tow vehicle hitch is called trailer tongue load
(conventional trailer) or king pin load (5th wheel or gooseneck trailers).
To measure trailer tongue/king pin load, place the tongue of the trailer on a scale when the
trailer is not attached to the
vehicle. A separate vehicle
jack — not the trailer jack —
should be used, as the
location of the trailer jack is
rearward of the trailer tongue
and will not give you an
accurate measurement of the
true tongue/king pin load.
Make sure the vehicle jack is
placed directly under the
trailer tongue coupler, and the tongue is set at the height/level of the tow vehicle hitch.
For proper handling, you must keep conventional trailer tongue load between 10-15% of
the actual trailer weight, within the limits of the maximum trailer tongue load allowable. For

2008 Nissan Towing Guide 14 example, to determine the proper trailer tongue load for a 1,500-lb. trailer, multiply the weight
of 1,500 lbs. by 10% to arrive at a figure of 150 lbs.
5th wheel and gooseneck trailer king pin load must be kept between 15-25% of the actual
trailer weight, within the limits of the king pin load allowable.
See the SPECIFICATIONS section of this guide or refer to your vehicle owner’s manual to
view the maximum conventional trailer tongue load listed for your vehicle.
NOTE – The vehicle weight ratings (GVWR, GAWR, GCWR, etc.) must not be
exceeded, regardless of trailer or hitch type.

HITCH & TRAILER HEIGHT
It is important that your trailer floor
and tongue ride as level as possible.
This will help prevent over-angling,
bottoming-out, and improper load
transfer. Therefore, the hitch or trailer
tongue must be adjusted during the
initial vehicle/trailer fit-up to ensure a
level ride. Ball mounts are available in
different configurations to
adjust the hitch ball height.

TIRE PRESSURE
When towing a trailer, increase tow vehicle tire pressures to the recommended cold
specifications. You will find these figures in the vehicle owner’s manual and on the tire
pressure chart located in the vehicle. Trailer tire condition, size, load rating, and inflation
pressure must be in accordance with the trailer and tire manufacturer’s specifications.


TOWING
SAFETY

Towing can dramatically alter the handling and performance characteristics of your vehicle.
Plus, it puts increased strain on the engine and drivetrain. Therefore, it is always a good idea
to approach towing from the standpoint of safety — whether you’re purchasing equipment or
actually pulling the trailer.
