Total Truck Weight

GVWR

Curb weight is the weight of the vehicle including a full tank of fuel and all standard equipment. It does not include the weight of any passengers, cargo, or optional equipment. Curb weight is considered the closest weight to the actual weight of the vehicle.

PLUS the combined weight of the driver and passengers.

PLUS the combined weight of all equipment, luggage, tools, which includes the weight of any options added to the truck.

PLUS Tongue weight is the downward force exerted at a vehicle-trailer coupling point when your trailer is hooked up for towing. The tongue weight should be about 10-15% of the gross trailer weight.

TOTAL This is the total weight of the truck.  

The Manufacturer’s Gross Vehicle Weight Rating is basically the maximum total safe weight of your vehicle.  The Total Truck Weight  must be less than the GVWR.

Example Calculation

7500 lbs.  +

425 lbs.  +

600 lbs.  +

500 lbs.  =

9025 lbs.

<  10000 lbs.

Quick Calculation for a Truck’s Safe Towing Weight

This calculations is simply the GCWR less the GVWR.
To calculate the actual maximum towing weight, for a specific situation, subtract the GCWR from the Total Truck Weight.

Safe Towing Weight

The Manufacturer’s Gross Combined Weight Rating (GCWR)  is the maximum safe weight of the truck and trailer.

The Gross Vehicle Weight Rating is basically the maximum total safe weight of your vehicle, counting the curb weight (the weight of our vehicle when empty), plus the weight of your passengers, any accessories added to the vehicle, cargo, and the “tongue weight” of a tow trailer (normally 10-20% of the combined …

Provided the GVWR of the truck has not been exceeded, then difference between the GCWR and GVWR is a safe towing weight.  Any weight amount under the GVWR can be added to the towing weight.
