GVWR – Gross Vehicle Weight Rating. This is determined by the manufacturer to be the weight of the vehicle PLUS its maximum recommended load. The manufacturer’s nomenclature plate may be metal or a sticker inside the vehicle, typically in the glove box or on the door frame. When vehicles are intended to be modified with items such as; interior shelves, racks, tools, snow plow, or a lift gate, the axle ratings or the tire ratings of the vehicle must be added together to determine the GVWR.
GCWR – Gross Combination Weight Rating. This is the value specified by the manufacturer as the maximum loaded weight of a combination vehicle, example: a truck and trailer. It can be calculated by adding the GVWR of the vehicle and the trailer or towed vehicle.
