Weight Of The Trailer Tongue; Total Weight On Your Vehicle's Tires - GMC 2003 Savana Owner's Manual

Weight of the Trailer Tongue

The tongue load (A) of any trailer is an important weight
to measure because it affects the total or gross weight
of your vehicle. The Gross Vehicle Weight (GVW)
includes the curb weight of the vehicle, any cargo you
may carry in it, and the people who will be riding in
the vehicle. And if you will tow a trailer, you must add
the tongue load to the GVW because your vehicle will be
carrying that weight, too. See Loading Your Vehicle
on page 4-30 about your vehicle's maximum load
capacity.
4-40
If you're using a weight-carrying or a weight-distributing
hitch, the trailer tongue weight (A) should be 10 percent
to 15 percent of the total loaded trailer weight (B).
Do not exceed the maximum allowable tongue weight
for your vehicle.
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 label at the rear edge of the driver's door or
see Loading Your Vehicle on page 4-30 . Then be
sure you don't go over the GVW limit for your vehicle,
including the weight of the trailer tongue.
