What does the GVWR of a trailer mean

GVWR stands for Gross Vehicle Weight Rating, and it's a number that represents a maximum value of what your vehicle can safely weigh including payload. To give you an example, your truck may have an 'empty' weight of 5,500 pounds (often called a “curb weight”) and a GVWR of 7,000 pounds.he gross vehicle weight rating (GVWR), or gross vehicle mass (GVM) is the maximum operating weight/mass of a vehicle as specified by the manufacturer including the vehicle's chassis, body, engine, engine fluids, fuel, accessories, driver, passengers and cargo but excluding that of any trailers.Pay load capacity is calculated by subtracting the weight of the empty trailer from the GVWR. Example: a trailer has a GVWR of 2,999 lbs and has a dead weight of 1,000 lbs - that means you are allowed to haul 1,999 lbs on that trailer assuming your hitch and vehicle weight ratings will allow it.To calculate your vehicle's payload capacity, you only need to know two things: your vehicle's gross vehicle weight rating (GVWR) and its curb weight. ... A vehicle's GVWR is calculated by its manufacturer, and you can typically find it in your owner's manual or on the vehicle's doorframe, near the door latch.Tare Weight + Rated Payload = GVWR. The second equation is: Upper Coupler Vertical Load or Front Tow bar Coupler Vertical Load + GAWR (s) = GVWR. Determining the GVW rating of a trailer involves far more than the sum of the capacity of the axles.
