Certification/Tire Label The Certification/Tire label also tells you the maximum weights for the front and rear axles, called Gross Axle Weight Rating (GAWR). To find out the actual loads on your front and rear axles, you need to go to a weigh station and weigh your vehicle. Your dealer can help you with this. Be sure to spread out your load equally on both sides of the centerline. Never exceed the GVWR for your vehicle, or the GAWR for either the front or rear axle. If you do have a heavy load, you should spread it out. Similar appearing vehicles may have different GVWRs and capacity weights. Please note your vehicle's Certification/Tire label or consult your dealer for additional details. Label Example A vehicle specific Certification/Tire label is attached to the bottom section of the center pillar, on the driver's side of the vehicle. Vehicles without a center pillar, extended cab models, will have the Certification/Tire label attached to the edge of the driver's side, extended cab door, below the door latch post. The label shows the Gross Vehicle Weight Rating (GVWR). The GVWR includes the weight of the vehicle, all occupants, fuel, cargo and trailer tongue weight, if pulling a trailer. {CAUTION: Do not load your vehicle any heavier than the Gross Vehicle Weight Rating (GVWR), or either the maximum front or rear Gross Axle Weight Rating (GAWR). If you do, parts on your vehicle can break, and it can change the way your vehicle handles. These could cause you to lose control and crash. Also, overloading can shorten the life of your vehicle. 4-47
