Weight of the Trailer Tongue The tongue load (A) of any trailer is an important weight to measure because it affects the total capacity weight of your vehicle.The capacity weight includes the curb weight of the vehicle, any cargo you may carry in it, and the people who will be ridingin the vehicle. And if you will tow a trailer, must subtract the tongue you load from your vehicle's capacity weight because your vehicle will becarrying that weight, too. See "Loading Your Vehicle" in the Index for more information about your vehicle'smaximum load capacity. If you're using a "dead-weight'' hitch,the trailer tongue (A) should weigh 10%of the total loaded trailer weight (B). If you have a "weight-distributing" hitch, the tmik tongue (A) should weigh 12% of the total loaded trailer weight (B). After you've loadedyour trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper. If they aren't, youmay be able to get them right simply by movingsome items around in the trailer. Total Weight on Your Vehicle's Tires Be sure your vehicle's tires are inflated to the recommended pressure 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" in the Index. Then be sure you don't go over the GVW limit for your vehicle, including theweight of the trailer tongue. 4-32
