Towing Capabilities

September 14th, 2021 by

Why is it crucial to know how much your vehicle can tow?

If done incorrectly, the vehicle can endure mechanical and cosmetic damages. Most importantly, safety is at risk for the driver, passengers, other vehicle driver/passengers, and pedestrians.


Every towing capable vehicle will have an information label located inside the driver’s door opening pillar. This label will have terms and the amount of LBS/KGS corresponding to the vehicle.



  • Curb Weight: Vehicle weight with mechanical fluids.
  • Tongue Weight: Total weight allowed on the trailer tongue.
  • GVWR (Gross Vehicle Weight Rating): Weight of the vehicle.
  • Max Payload: Maximum weight the vehicle can bear with passengers.
  • GAWR (Gross Axle Weight Rating): Maximum amount the axle systems can safely carry.
  • GCWR (Gross Combined Weight Rating): Total supported weight of the trailer, vehicle, passengers, cargo, and mechanical fluids.
  • TWR (Trailer Weight Rating): The number shown is made up of an estimation of GCWR minus Curb Weight. In the calculation, they used 300 pounds for the driver and one passenger. The actual weight of people and cargo need to be added in the equation.




The GCWR is 15,000 pounds, the Curb Weight is 6,000 pounds, one passenger is 220 pounds, another passenger is 150 pounds, cargo is 1,000 pounds, the trailer is 1,000 pounds, and the boat is 4,000 pounds.

GCWR – Curb Weight – Cargo – Passenger Weight= Towing Capacity

15,000 – 6,000 – 1,000 – 370= 7,630 

Trailer + Boat= Towing Weight

1,000 + 4,000= 5,000

Since the towing weight doesn’t exceed the towing capacity, it is safe to tow and carry the weight with 2,630 pounds in excess.


Most vehicles, including the 2021 Chevrolet Silverado, have many features to help make towing easier and safer!
