To determine your gross vehicle weight rating, check the label that is usually situated near the driver's door latch on the frame of the vehicle's door. You can also determine this value by searching the information on the vehicle manufacturer's website.
As opposed to gross vehicle weight, which is the actual weight of the vehicle that varies according to the load weight, gross vehicle weight rating is a constant maximum weight of the vehicle that should not be surpassed by the vehicle load. For instance, if a car has a 1-tonne cargo aboard, and the cargo is offloaded, the gross vehicle weight of the car decreases by 1 tonne, while the gross vehicle weight rating remains intact. On the other hand, if the same cargo is loaded onto the car, the gross vehicle weight rises by 1 tonne, while the gross vehicle weight rating still remains unaffected.
Gross vehicle weight rating covers the curb weight, cargo weight, passengers' weight and the weight of any added accessories. When the gross vehicle weight rating is exceeded, the vehicle may experience braking problems and compromised suspension. An overloaded vehicle can also prompt overheating and eventual bursting of the tires. To avoid these complications, vehicle owners should consider the gross vehicle weight rating when loading their vehicles.
