Total Weight on Your Vehicle's Tires Be sure your vehicle's tires are inflated to the upper limit for cold tires. You will find these numbers on the Certification/Tire Label at the rear edge of the driver's door, or see Loading Your Vehicle on page 4-31. Do not go over the GVW limit for your vehicle, including the weight of the trailer tongue. Hitches If you are using a weight-carrying or 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. After you have loaded your trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper. If they are not, you may be able to get them right simply by moving some items around in the trailer. It is important to have the correct hitch equipment. Crosswinds, large trucks going by, and rough roads are a few reasons why you will need the right hitch. Here are some rules to follow: • If you will be pulling a trailer that, when loaded, will weigh more than 2,000 lbs (900 kg), use a properly mounted, weight-carrying hitch and sway control of the proper size. This equipment is very important for proper vehicle loading and good handling while driving. • Will you have to make any holes in the body of your vehicle when you install a trailer hitch? If you do, remember to seal the holes when you remove the hitch. If you do not seal them, deadly carbon monoxide (CO) from your exhaust can get into your vehicle. See Engine Exhaust on page 2-29. Dirt and water can, too. 4-41
