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 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 4-34 for more information about your vehicle's maximum load capacity. If you're using a weight-carrying hitch or a weight-distributing hitch, the trailer tongue (A) should weigh 10-1 5 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 Tire-Loading Information Label at the rear edge of the driver's door, or see Loading Your Vehicle on page 4-34. Then be sure you don't go over the GVW limit for your vehicle, including the weight of the trailer tongue. 4-38
