Total Weight on Your Vehicle's Tires Be sure your vehicle's tires inflated to the upper limit are for cold tires. You'llfiid these numbers on the Tire of Loading Information label located at the rear edge the driver's door or see "Loading Your Vehicle" in the Index. Then be sure you don't over the GVW limit for your go vehicle, including the weightof the trailer tongue. A B Hitches It's important to have the correct hitch equipment. Crosswinds, large trucksgoing by and rough roadsare a few reasons why you'll need the right hitch. Here are some rules to follow: The bumpers on your vehicle are not intended for hitches. Do not attach rental hitches or other bumper-type hitches to them, Use only a frame-mounted hitch that does not attach to the bumper. Will you have to make any holes in the body of your vehicle when you install a trailer hitch? you do, If then be sure to seal the holes later when youremove the hitch. If you don't seal them, deadly carbon monoxide (CO) from your exhaust can get into your vehicle (see "CarbonMonoxide" in the Index). Dirt and water can, too. 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 trailertongue (A) should weigh 12 percent of the total loaded trailer weight (B). After you've loaded your trailer, weigh trailer and the then the tongue, separately, to see if the weights are to proper. If they aren't, you may be able get them right simply by moving some items around in thetrailer. 4-35 ~
