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 label at the rear edge of the driver’s door 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 use a step
- bumper hitch, your bumper could
be damaged in sharp turns. Make sure you have
ample room when turning to avoid contact between
the trailer and the bumper.
D If you’ll be pulling a trailer that, when loaded, will
weigh more than the capacity stamped on your step
bumper, 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.
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.
For trailers up to 5,000 lbs. (2 270 kg) you may attach
the safety chains to the attaching points on the bumper.
For heavier trailers, follow the trailer or hitch
manufacturer’s recommendation for attaching safety
chains. Always leave just enough slack so you can
turn with your rig. Never allow safety chains to drag
on the ground.
