Overloading a vehicle punishes components and can lead to shortened service life or outright failure. The capacity of the tires is included as part of the axle and suspension system, which is to be considered when determining the lowest rated component. Tires are rated to carry a specific maximum load at a specific maximum tire pressure. Passenger car type tires when installed on light trucks and multipurpose passenger vehicles are rated at 10% lower load carrying capacity due to the differences in vehicle usages. The vehicle must not be loaded to both the front and rear GAWR because the GVWR will be exceeded. The GAWR of the front and rear axles exceed the GVWR when added together to allow flexibility in fore and aft loading of cargo. 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. GCWR (Gross Combined Weight Rating) GCWR is the maximum combined weight of the towing vehicle (including passengers and cargo) and the loaded trailer. The GCWR is specified by the manufacturer to indicate the combined maximum loaded weight that the vehicle is designed to tow. Maximum Trailer Weight Rating The maximum weight of a trailer the vehicle is permitted to tow. The maximum trailer weight rating is specified by the manufacturer and is determined by subtracting the vehicle curb 220
