Gross weight = Curb + People + Cargo + Tongue weight · Combined = Gross weight + Trailer − Tongue weight
The tongue weight sits on the truck, so it counts in the truck’s gross weight and isn’t counted twice in the combined weight. With the example: 6,000 + 400 + 1,200 + 800 = 8,400 lb of an 8,800 lb GVWR, and 14,600 lb combined against 16,000. Also stay under each axle’s rating (GAWR) and the hitch’s rating. A truck scale gives the real numbers; weigh before a heavy job.
Using the numberWhat to do with it
- Service trucks gain weight over time as tools and parts pile up; weigh them once a year.
- Over-GVWR trucks wear brakes, tires and suspension faster; check them more often.
- GVWR also decides which rules and licenses apply to a truck, so know it for every unit.

Good to know
What is GVWR?Gross vehicle weight rating: the most the vehicle may weigh fully loaded, including passengers, cargo and tongue weight. It's on the door sticker.
How do you calculate payload capacity?Payload capacity = GVWR − curb weight. Subtract passengers, cargo and tongue weight to see what's left.
What is GCWR?Gross combination weight rating: the most the truck and trailer may weigh together. It's in the owner's manual or towing guide.
