GVWR stands for Gross Vehicle Weight Rating. It is the legal and structural weight limit set by the manufacturer, encompassing the curb weight of the vehicle plus all passengers, cargo, fuel, and the tongue weight of any towed trailer. Exceeding this rating overloads the brakes, tires, and suspension, leading to component failure and unsafe handling.
You can't haul that pallet of concrete in a half-ton truck because it puts you way over the GVWR.
Do not mix it up with
