Calculate Axle Weights Instantly



Formula Used

Drive Axle Weight = Tractor Weight - Steer Weight

Trailer Axle Weight = Total Weight - Tractor Weight

In this formula:

  • Total Weight is the total weight of the truck and trailer in lbs.
  • Tractor Weight is the weight of the tractor unit in lbs.
  • Steer Weight is the weight on the steer axle in lbs.
  • Drive Axle Weight is calculated by subtracting the steer weight from the tractor weight.
  • Trailer Axle Weight is calculated by subtracting the tractor weight from the total weight.

Examples

Total Weight (lbs) Tractor Weight (lbs) Steer Weight (lbs) Drive Axle Weight (lbs) Trailer Axle Weight (lbs)
80000 18000 12000 6000 62000
75000 16000 11000 5000 59000

Frequently Asked Questions (FAQs)


What is axle weight?

Axle weight refers to the weight distributed over a single axle of a vehicle. In a semi-truck, weight is typically distributed among the steer axle, drive axle, and trailer axle.

Why is it important to know the axle weights?

Knowing the axle weights is crucial for maintaining safe vehicle operation, preventing damage to road surfaces, and ensuring compliance with legal weight limits for trucks on public roads.

How can I change the weight distribution of my truck?

You can change the weight distribution of your truck by shifting or redistributing the load. Keep in mind that this should always be done in accordance with safety regulations and weight limits.

Can I use this calculator for other types of vehicles?

Yes, you can use this calculator for other types of vehicles as long as you know the total weight and the weights on the axles. Just keep in mind that the results may not be as accurate for vehicles with significantly different weight distributions than semi-trucks.
