276 STARTING AND OPERATING The bar code allows a computer scanner to read the Vehicle Identification Number (VIN). Gross Vehicle Weight Rating (GVWR) The GVWR is the total allowable weight of your vehicle. This includes driver, passengers, and cargo. The total load must be limited so that you do not exceed the GVWR. Tire Size The tire size on the Vehicle Certification Label represents the actual tire size on your vehicle. Replacement tires must be equal to the load capacity of this tire size. Rim Size This is the rim size that is appropriate for the tire size listed. Inflation Pressure This is the cold tire inflation pressure for your vehicle, for all loading conditions. Curb Weight The curb weight of a vehicle is defined as the total weight of the vehicle with all fluids, including vehicle fuel, at full capacity conditions, and with no occupants or cargo loaded into the vehicle. The front and rear curb weight values are determined by weighing your vehicle on a commercial scale before any occupants or cargo are added. Overloading The load carrying components (springs, tires, wheels, etc.) of your vehicle will provide satisfactory service as long as you do not exceed the GVWR. The best way to figure out the total weight of your vehicle is to weigh it when it is fully loaded and ready for operation. Weigh it on a commercial scale to ensure that it is not over the GVWR.
