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 ioading Your Vehicle onpage 4-49. Then be sure you don't go over the GVW limit for your vehicle, including the weight of the trailer tongue. Hitches A B 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: 0 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. If you'll be pulling a trailer that, when loaded, will weigh more than 3,500 Ibs. (1 589 kg), 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. Will you have to make any holes in the body of your vehicle when you install a trailer hitch? If you do, then be sure to seal the holes later when you remove the hitch. If you don't seal them, deadly carbon monoxide (CO) from your exhaust can get into your vehicle. See Engine Exhaust on page 2-39 and "Driving with a Trailer" later in this section. Dirt and water can, too. 4-55 After you've loaded your trailer, weigh the trailer and then the tongue, separately, to seethe weights are proper. if If they aren't, you may be to get them right simply by able moving some items around the trailer. in
