Tire Pressure Monitoring System Vendor Support

You can integrate with a supported Tire Pressure Monitoring System (TPMS) to track and monitor tire conditions across your fleet. 

• Pressure Pro

How it works

Samsara offers several dashboard features that surface tire condition data:

• Vehicle Show Page Summary

• Tire Condition Graph and Panel

• Tire Condition Maintenance Page

• Tire Condition Alerts

Vehicle Show Page Summary

To arrive at a particular unit’s vehicle show page, select the unit from the List view of the Fleet page.

Once hardware installation is successfully complete, the Tire Condition will appear under the Sensors section of the vehicle show page.

The Tire Condition surfaces the most recent tire condition reported. The number of tires associated with the assets are reported underneath Tire Condition. In the example above, there is one tire with extreme over pressure reported.

Hovering over the trailer image under the Sensors section reveals the View Details option, which expands a visual representation of the trailer with each tire condition value and a timestamp detailing the last time the tire diagnostic was reported.

The visual representation of the trailer is also accessible by clicking on the status link located at the right of Trailer Tire Condition under the Sensors section.

When hovering over a tile in the trailer display (the tiles represent tire positioning on a trailer as indicated by the user via their PressurePro gateway), the users are presented the following data:

• Axle number (Axle 1, Axle 2, etc)

• Tire position (Right Outer, Left Inner, etc)

• Timestamp of last received/surfaced sensor data

• Tire condition (Normal, Critical, etc)

• Pressure (Current or last received value)

• Set Point (Current or last received value)

• Temperature (Current or last received value)

The panel that surfaces when hovering over the tires shows each of the tires in their intended configuration - the PSI and temperature are displayed for each individual tire.

To inspect the recent history of a trailer’s tire pressure, users have the ability to view tire pressure history in the vehicle show page with an overlay graph. On the left hand panel, users can click on the sparkline to the right of Tire Condition.

Once selected, an overlay graph will appear above the map. Users can select individual or multiple tires to view at the same time.

Users can also hover over the graph to view time-specific values for pressure, pressure set point, and temperature. As users hover over specific areas of the graph, the asset location on the map will adjust to indicate its recorded location during that timeframe.

This data on the graph is also exportable. By selecting the Download CSV option at the bottom right hand corner of the graph, users can download pressure, pressure set point, and temperature data from one or more tires. The downloaded file will include information of all selected tires for the specified time range.

Tire Condition Maintenance Page

To access the Tire Condition page, select Maintenance from the Fleet list view and locate Tire Condition from the list on the left side of the page:

The top of the Maintenance page displays an Overall asset tire status that summarizes tire conditions across the fleet:

In cases when multiple tire conditions are reported for an asset, the most critical condition is reported.
For example, if an asset contains Cautionary and Critical tire conditions, the asset will be marked as Critical.

The asset list can be filtered by criticality by either clicking on a tire condition on the Overall asset tire status or by using the Tire Status drop-down menu.

Underneath the Overall asset tire status, all assets are listed with their current location, current driver, and the most critical tire status. Selecting an asset from the list reveals the axle, tire position, pressure, set point, temperature and tire statuses of all tires attached to the asset:

If a Tire Status is selected, the Expand All/Collapse All option becomes available. Selecting it will expand or collapse all of assets in the list:

The top-right of the page contains a menu that allows the user to export the report to a CSV file or output a PDF to print the report.

The Export to CSV option outputs a CSV that contains the following columns for all tires in the current view, applying any filter set:

The Print options prompts the user to print a printer-friendly version of the report currently in view:

Tire Condition Alerts

You can set up alerts to receive notifications for any tire condition. Alerts can be set for specific tire conditions and/or for alerts with a certain level of criticality (cautionary/critical).

For full instructions on setting up alerts, see Create an Alert Configuration (Alerts v 2.0). During configuration, you will select the Tire Fault Code alert type, and then choose the alert provider, one or more specific fault codes, and the alert source (all assets, specific assets, or specific tags). 

The alert will trigger if the tire condition reported by the PressurePro gateway holds for a specified amount of time. After the alert triggers, Samsara sends a text/email alert to the contact set in the alert.

The alert contains the affected tire and the specific fault codes associated with the report.

Here’s an example email alert:

** Samsara Alert: Asset has a tire fault. ***

Axle 6 Left Outer has fault codes: 'Across axle fault'. Pressure is 88.2 PSI and temperature is 190.6 °F.

Axle 6 Left Inner has fault codes: 'Across axle fault'. Pressure is 99.2 PSI and temperature is 190.6 °F.

Axle 6 Right Inner has fault codes: 'Across axle fault'. Pressure is 109.6 PSI and temperature is 30.4 °F.

Axle 6 Right Outer has fault codes: 'Across axle fault'. Pressure is 100.9 PSI and temperature is -9.7 °F.

The alert will resolve after the tire condition no longer holds.
