- Axle Weight Distribution Formula
There are a number of trailer axle configurations, weight limit rules and regulations, and terms that can make understanding axle weight intimidating. Understanding the basic terms and calculations of axle weight, along with access to the right resources will have you talking and calculating axle weight with confidence. TruckingAgents.net provides the resources and education to help make drivers, agents, brokers, and dispatchers have a better understanding of axle weight and how they affect shipments.
As with any profession, knowing the terms is necessary to have a productive conversation. Below, is a basic tractor trailer axle configuration and the axle types. When discussing axle weights, refer to the axles by the terms listed below.
- TruckScience - Software for Truck Axle Weight Distribution, Fuel Consumption Simulation and Sales Tool including TCO - Total Cost of Ownership.
- Distribution software. It calculates the 'how to' load the trucks, containers, pallets, rail cars, boxes and ULDs with single and mixed size products. CubeMaster is the easies and most powerful cargo load plan and optimization software for truck, container, pallet and carton. Axle weight calculations help minimize transient damage.
- Steer Axle - As the name implies, it is the axle that a steers the tractor.
- Drive Axles - The drive axles receive the power from the engine.
- Trailer Axles - They are the rear axles on the trailer and they don't steer or receive power.
Axle Groups
Does anyone know the FPC code to change the weight distribution of the axles? In the past it was possible to change in SDP but not anymore. I have a 5 axle truck where I need to change the weight distribution on the axles. So for example 9000, 9000, 10000, 10000, 9000. Can pay for info if needed.
An axle group can consist of 1 or more axles, and are commonly seen and referred to as the following:
- One - Single Axle Group
- Two - Tandem Axle Group
- Three - Tri-Axle Group (Tridem)
- Four - Quad Axle Group
Legal Axle Weights Tractor Trailer
Now that we can label the axle types and groups we can talk about axle weight.
Axle Weight - Refers to the legal allowable gross axle weight on any particular axle group and type.
Although the state's and province's axle weight limits can vary, we can discuss what is most common. A common five axle tractor trailer combination has the following axle weight limits.
12,000 + 34,000 + 34,000 = 80,000
When you add the axle group limits you get a total of 80,000 lbs, which is the standard max gross weight a tractor trailer can be without an overweight permit. This max gross weight is going to include everything:
- Tractor
- Trailer
- Commodity
- Fuel
- Driver
12,000 + 28,000 + 40,000 = 80,000
Here is an example of the advantage gained by using a tri-axle trailer group. In this example image, the commodity is setting toward the back half of the trailer and so more of the commodity weight is on the trailer axles than on the drive axles. Because the trailer axle group is a tri-axle configuration it can carry more weight legally. It's important to point out that this example still does not exceed the gross weight limit of 80,000 lbs.
Van Trailer
A van trailer has the same rules as open deck trailer equipment on axle weights, but because van trailers typically haul palletized goods the weight is generally evenly distributed over the trailer and gross weight does not exceed the 80,000 lbs limit.
If the commodity hauled exceeds the axle group weight limit, then an overweight permit is required. A shipment would require an overweight permit even if only one axle group exceeds the axle group limit and the gross shipping weight does not exceed the 80,000 lbs.
12,000 + 30,000 + 38,000 = 80,000

The gross limit in this example does not exceed 80,000 lbs, but the trailer tandem axles exceeds the 34,000 lbs gross weight limit. The driver could try and reposition the load to move more weight from the rear trailer axles to the drive axles. If that is not possible, the driver would be required to haul this shipment with an overweight permit.

Axle Load Calculations – Axle Weight and Wheelbase Configuration.
Manufacturers, bodybuilders, and modifiers must ensure that the axle loads are optimised for maximum legal limit when a body is fitted onto a cab chassis, or when a wheelbase is modified. It is very important to ensure that no axle on the vehicle is over loaded the legal limits or OEM ratings.
Commercial Vehicle Compliance can provide a Axle Load Calculations report including a layout drawing for the vehicle dimensions, ideal body position or wheelbase and weight charts for front and rear axles. This provides a blueprint for the workshop, record for the manager and a sales tool for the client.
This service carried out before the modifications can save time and money, achieve maximum payload, and comply to legal limits.
