Truck Towing Capacity

How much weight a pickup truck can pull can vary hugely, even between two pickups that look identical. That’s why finding out your towing capacity by VIN is more accurate. Factors that can affect a pickup truck towing capability include:

  • Engine Type
  • Axle Ratios
  • Transmissions
  • Chassis
  • Suspension
  • Tires and load ratings
  • Hitch type and class
  • Trailer type

Calculating towing capacity

With so many variables between truck builds and manufacturers, it can take a few minutes to figure out exactly what the max towing capacity of your specific vehicle is. The combined weight of your truck plus trailer and cargo should not exceed the max tow capacity. You’ll need some information from the VIN or door sticker on the truck.

  • GVWR – Gross Vehicle Weight Rating (how much weight your vehicle with passengers, fuel, and cargo can carry).
  • GCWR- Gross Combined Weight Rating (the max total weight of everything combined, ie. your truck, passengers, trailer and cargo).
  • GAWR- Gross Axle Weight Rating (the amount of weight that can be placed over each axle).
  • Curb Weight- This is how much your vehicle weight without anyone in it or any cargo.
  • Tongue Weight- How much weight the hitch can handle.

Some owners manuals may have towing capacities in there, however, some of the newer ones don’t due to the variations on each truck build.


Towing capacity formula

  1. Find out curb weight (on VIN sticker).
  2. Add the weight of passengers, fuel, and cargo to the curb weight.
  3. Subtract this number from your vehicle’s GCWR ( you may have to look this up using your VIN if it’s not on the door sticker).
  4. This is your max towing capacity.
  5. Check to make sure the hitch can also handle this weight.
