Which of the following items is not typically included in GVW calculations?

In Gross Vehicle Weight (GVW) calculations, the primary factors considered are the truck's weight (which includes the chassis and any built-in components), the driver’s weight, and the weight of the cargo being transported. These elements combined give an accurate representation of the total weight that the vehicle is carrying.

The reason tires' weight is typically not included in these calculations is that the weight of the tires is already accounted for in the overall weight of the truck when measured. GVW focuses mainly on the vehicle's operational and load-carrying capacity, and adding the tire weight separately would be redundant since it is part of the truck's gross weight. By concentrating on the truck, driver, and cargo, GVW provides a clear indicative figure necessary for ensuring compliance with weight limits and for safe operation on roadways.
