Total Weight on Your Vehicle’s Tires

Be sure your vehicle’s tires are inflated to the
upper limit for cold tires. You will find these
numbers on the Certification/Tire label at the rear
edge of the driver’s door or see Loading Your
Vehicle
on page 378. Then be sure you do not go
over the GVW limit for your vehicle, including
the weight of the trailer tongue.

Hitches

It is important to have the correct hitch equipment.
Crosswinds, large trucks going by, and rough
roads are a few reasons why you will need
the right hitch. Here are some rules to follow:

The bumpers on your vehicle are not intended
for hitches. Do not attach rental hitches or
other bumper-type hitches to them. Use only a
frame-mounted hitch that does not attach to
the bumper.

Will you have to make any holes in the body
of your vehicle when you install a trailer
hitch?

If you do, remember to seal the holes later
when you remove the hitch. If you do not seal
them, deadly carbon monoxide (CO) from
your exhaust can get into your vehicle. See
Engine Exhaust on page 141. Dirt and
water can, too.

Safety Chains

You should always attach chains between your
vehicle and your trailer. Cross the safety
chains under the tongue of the trailer to help
prevent the tongue from contacting the road if it
becomes separated from the hitch. Instructions
about safety chains may be provided by the hitch
manufacturer or by the trailer manufacturer.
Follow the manufacturer’s recommendation for
attaching safety chains and do not attach them to
the bumper. Always leave just enough slack so
you can turn with your rig. Never allow safety
chains to drag on the ground.
