How TBATIS Works
Air from the trailer air supply is routed to a central control box, then into each axle. The axles act as conduits to carry air through a rotary union assembly, which distributes air to each tire as needed.
The TruBlu Tire Inflation System™ and Fleet Operation
Trailers are essential for transporting goods, making consistent operation a priority. Extended time on the road requires effective systems to maintain performance and minimize disruptions. A key challenge for fleet managers and drivers is maintaining proper tire pressure, as fluctuating or low pressure can affect safety and overall efficiency.
How TruBlu TIS Addresses Tire Pressure Issues
TruBlu TIS uses pressurized air from the trailer’s supply tank to keep tires inflated and reduce tire-related issues. It filters the air and distributes it to the tires through the control box and axle tube, ensuring proper tire pressure while still requiring regular manual checks for optimal performance and safety.
Additional Features of theTire Inflation System
TruBlu TIS was among the first automatic tire inflation systems and is used in various fleet operations. According to studies, TRUBLU TIS may contribute to extended tire life and improved fuel economy. Other reported benefits include potential cost savings and fewer tire-related incidents.
Cost and Efficiency Aspects
TruBlu TIS provides real-time tire air pressure monitoring to help drivers prevent downtime and avoid penalties from underinflated tires. With features like leak detection for easier maintenance, fleets typically see a return on investment within one to two years based on tire usage patterns.
Maintenance and Roadside Functionality
In high-use fleets, underinflated tires can reduce tread life, affect fuel economy, and increase blowout risk. TRUBLU TIS offers real-time airflow and pressure monitoring, alerting drivers to tire issues promptly. Improved tire maintenance may contribute to sustained fleet operation over time.
Installation Flexibility
TruBlu TIS is designed for compatibility with most trailer types and axle models, supporting ease of installation and adaptability across fleets. The system provides ongoing monitoring of tire pressures during transit.
Standard ThermALERT™ System
The Standard ThermALERT feature notifies drivers when wheel-ends reach high temperatures, helping prevent damage or hazards. This can potentially promote greater road safety and reduce fleet downtime.
Cummins and TruBlu TIS
Cummins develops commercial transportation solutions, including TRUBLU TIS with ThermALERT, focusing on operational efficiency and safety. The company works toward providing technologies that support regulatory compliance and evolving industry needs.
Semi-Trailer Tire Inflation System

Key Features & Benefits of ATIS:
- Consistent Tire Pressure: ATIS automatically maintains optimal tire pressure, preventing over-inflation or under-inflation, which can lead to tire damage, reduced fuel efficiency, and safety risks.
- Increased Tire Life: Proper inflation extends tire life by minimizing wear and tear on the tire casing.
- Improved Fuel Economy: Running tires at the correct pressure can reduce fuel consumption.
- Enhanced Safety: Maintaining optimal tire pressure reduces the risk of blowouts and tire-related accidents.
- Reduced Downtime: By preventing tire failures, ATIS can minimize costly road service calls and downtime.
- Load-Based Adjustments: Some systems, can adjust tire pressure based on the trailer’s load to optimize tire contact patch.
- Wheel-End Heat Detection: Some systems, can detect overheating wheel-ends and alert drivers, preventing further damage.
