Formula Used

Drive Axle Weight = Tractor Weight – Steer Weight

Trailer Axle Weight = Total Weight – Tractor Weight

In these formulas:

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 of Semi-Truck Axle Weight Limits

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

What is Axle Weight?

Axle weight refers to the weight distributed over a single axle (or the weight spread across consecutive axle groups) of a commercial vehicle. In a semi-trailer truck, weight is typically distributed among the steer axle (front axle), drive axle (rear axle), and trailer axle (tractor weight minus total weight).

It’s important to note that this includes the truck’s gross vehicle weight plus the weight of the cargo. Further, overloading your axles (as specified in the manufacturer’s specs or by law) can result in:

Fines
Increased wear and tear on your axles
Safety hazards

Frequently asked questions (FAQs)

Why is it important to know the axle weights?

Knowing the axle weight rating 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, the manufacturer’s axle rating, and maximum legal 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 axle weight limits. Just keep in mind that the results may not be as accurate for vehicles with significantly different weight distributions than semi-trucks.
