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 atthe 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 the weight of the trailer tongue. B Hitches It's important to have the correct hitch equipment. Crosswinds, large trucks going by and rough roads a are few reasons why you'll need the right hitch. Here are some rules to follow: 0 The rear burnper on your vehicle is not intended for hitches. Do not attach rental hitches or other bumper-type hitches to it.Use only a frame-mounted hitch that does not attach to the bumper. 0 If you're using a weight-carrying hitch, the trailer tongue (A) should weigh 10 percent of the total loaded trailer weight (B). If you have a weight-distributing hitch, the trailer tongue (A) should weigh 12 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. Will youhave 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 "Carbon Monoxide" in theIndex). Dirt and water can, too. 4-37 -
