While riding next to a semi-truck or other heavy truck, you have noticed an object resembling an odometer attached to a tire. That little circular device is called a Hubodometer, as well as it is needed for heavy-vehicle operators.

How Is a Hubodometer Used?

Hubodometers provide a dependable record of kilometers or miles as well as are generally used on heavy vehicles like buses, trucks, coaches, along with trailers. They are very useful:

To Calculate ROI

Because the hubodometer is perfect, its distance reading can be used to assist compute the cost per kilometer on equipment that does not have an odometer.

To Monitor Trailers

Trailers do not have odometers, so the exact way to precisely measure how remote a trailer has traveled is by using a Hubo.

Maintenance Schedules

For heavy vehicles such as trailers that do not have odometers, maintenance schedules can be scheduled around specific distances.

For the Calculation of Levies or Charges

A number of countries have distance-based levies for heavy vehicles because they cause more tear and wear on the roads.

For Distance-Based Rating

Business entrepreneurs can use Hubodometer readings to precisely bill customers if they are charging remotely.

The Characteristics of a Hubodometer

A Hubodometer will have a reading that generally shows the distance. They will also be waterproof as well as must be able to function at very low and high temperatures. They must be immune to manipulation. The Hubodometer is calibrated for the certain tire size of the tire on a similar axle.

How Does It Work?

The outer part of the Hubo rotates with the axis, although the inner part of the Hubo has a weight inside it that keeps it pointing downstairs. Each time a rotation is done, it counts one more unit as well. Also read about What’s a Hubodometer or Hubo? to click here.

How Often Should a Hubodometer Be Tested?

A driver must check the Hubodometer when he performs the pre-trip inspection. Also, it will have a service interval.

Where the Hubodometer Should Be Placed?

A Hubodometer should not be mounted on a lifting axle. It should always be on the left side of the car to let it be checked at the side of the road without putting the individual checking it in the traffic lane.

Strengths and Weaknesses of the Hubodometer

Mechanical hubodometers just measure the revolutions of a tire. By the way, the tire wears out it gets minor and this raises the number of times it turns each kilometer leading to incorrectness. The Hubodometer has been calibrated to average this incorrectness over time. Mechanical Hubodometers can be handled whether the individual has the correct tools as well as they wear out gradually. 


In summary, Hubodometers are indispensable trailer parts near you, essential for heavy-vehicle operators to accurately track kilometers or miles traveled. They serve crucial functions such as calculating ROI, monitoring trailers, scheduling maintenance, and determining levies or charges based on distance. Despite potential limitations like susceptibility to manipulation and wear in mechanical models, technological advancements have led to more flexible and durable Hubodometers, offering improved tracking capabilities and easier readability. As a result, they play a pivotal role in enhancing fleet management efficiency.
