PSI Tire Inflation Systems: What Fleets Should Inspect and Maintain
Automatic tire inflation systems help keep trailer tires at the right pressure, which reduces blowouts and improves tire life. But they’re not set-and-forget.
What to inspect
- Airline routing and abrasion points
- Hub caps and fittings (leaks)
- System indicator function
- Wheel-end seals and contamination signs
If your trailers run PSI systems, include checks in your routine PM. Ask about trailer PM.
