If you’re using a weight
-
carrying hitch, the trailer
tongue (A) should weigh 10 percent of the total loaded
trailer weight (B). If you’re using a weight
-
distributing
hitch, the trailer tongue (A) should weigh 12 percent of
the total loaded trailer weight (B).
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 get them right
simply by moving some items around in the trailer.
Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inflated to the upper limit for
cold tires. You’ll find these numbers on the Certification/Tire
label on the driver’s door edge, above the door latch, or see
“Tire Loading” in the Index. Then be sure you don’t go over
the GVW limit for your vehicle, including the weight of the
trailer tongue.
Hitches
It’s important to have the correct hitch equipment.
Crosswinds, large trucks going by and rough roads are a
few reasons why you’ll need the right hitch. Here are
some rules to follow:
D If you’ll be pulling a trailer that, when loaded, will
weigh more than 3,500 lbs. (1 589 kg), be sure to use
a properly mounted, weight
-
distributing hitch and
sway control of the proper size. This equipment is
very important for proper vehicle loading and good
handling when you’re driving.
D Will you have to make any holes in the body of your
vehicle when you install a trailer hitch?
If you do, then be sure to seal the holes later when
you remove the hitch. If you don’t seal them, deadly
carbon monoxide (CO) from your exhaust can get
into your vehicle (see “Carbon Monoxide” in the
Index). Dirt and water can, too.
