322 STARTING AND OPERATING Hour of manufacture. The bar code that appears on the bottom of the label is your Vehicle Identification Number (VIN). Gross Vehicle Weight Rating (GVWR) The GVWR is the total permissible weight of your vehicle including driver, passengers, vehicle, options, and cargo. The label also specifies maximum capacities of front and rear axle systems. Total load must be limited so that GVWR is not exceeded. Payload The payload of a vehicle is defined as the allowable load weight a truck can carry including the weight of the driver, all passengers, options, and cargo. Gross Axle Weight Rating (GAWR) The GAWR is the maximum permissible load on the front and rear axles. The load must be distributed in the cargo area so that the GAWR of each axle is not exceeded. Each axle GAWR is determined by the component in the system with the lowest load carrying capacity (axle, springs, tires, or wheels). Heavier axles or suspension components sometimes specified by purchasers for increased durability do not necessarily increase the vehicle's GVWR. Tire Size This is the minimum allowable tire size for 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 (Cold) This is the cold tire inflation pressure for your vehicle for all loading conditions up to full GAWR.
