Total Weight on Your Vehicle's Tires Be sure your vehicle's tires are inflated to theupper limit for cold tires. You'll find these numbers on the Certificatioflire label on the driver's door edge, above the door latch, or see "Tire Loading" in the Index. Then be sure you don't goover 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 roadsare a few reasons why you'll need right hitch. Here are the some rules to follow: If you'll be pulling a trailer that, when loaded, will weigh more than 3,500 lbs. (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 vehicleloading and good handling when you're driving. 0 If you're usinga weight-carrying hitch, the trailer tongue (A) should weigh 10 percent of the total loaded trailer weight (B). If you're using a weight-distributing hitch, the trailer tongue (A) should weigh 12 percent of the total loaded trailer weight (B). After you've loaded yourtrailer, 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 you have to make any holes inthe body of your vehicle when you install a trailer hitch? If you do, then be sure to seal theholes later when you remove thehitch. If you don't seal them, deadly carbon monoxide(CO) from yourexhaust can get into your vehicle (see "Carbon Monoxide" in the Index). Dirt and watercan, too. 4-45
