Axle weight

Last reviewed: 2026-05-20

The actual measured load carried by a single axle at any given time. Axle weight varies by cargo loading, cargo distribution, fuel level, and trailer type. The correct tire inflation pressure for each axle position is determined by the actual axle weight, not by a default fleet setting.

Use a loaded scale ticket when determining the correct tire pressure for a specific axle. Guessing at axle weight leads to both over- and under-inflation.

Real-World Use

A driver picking up a dense load that is concentrated forward in the trailer notes a significant steer axle weight increase at the scale — maintenance adjusts tire pressure to the correct setting for the new axle weight before dispatch.
