Driving When passenger car tires are installed on light trucks and multipurpose passenger vehicles, they are rated at a 10% lower load carrying capacity due to the differences in vehicle usages. With the tires inflated to the specified pressure, the total weight of your vehicle must not exceed the GVWR and GAWR specified on the Safety Compliance Certification Label. This includes full fuel tank(s), vehicle equipment, and occupants, as well as the cargo load. Gross Combined Weight Rating (GCWR) The GCWR is the maximum allowable weight of the towing vehicle and the loaded trailer (including all cargo and passengers). Calculating the Payload for Your Vehicle To know how much weight your vehicle can carry: 1. Obtain the GVWR and GAWR from your Safety Compliance Certification Label. - If you do not plan to pull a trailer, do not include these ratings into your calculations. 2. Fill the fuel tank. 3. Weigh your vehicle without cargo. 4. Subtract vehicle actual weight from the GVWR to find out how much more weight your vehicle can carry. 5. Weigh the vehicle again once it is loaded to make sure that the GVWR and front and rear GAWR's are not exceeded. 223
