Tire Pressure Monitoring Systems (TPMS) are powerful tools—but only if used correctly. Most modern TPMS has two types: direct (sensors in tires) and indirect (uses ABS data). Direct TPMS is more accurate, but sensors need battery replacement every 5-7 years—watch for intermittent alerts, which signal low battery. Calibrate TPMS after adjusting pressure, rotating tires, or replacing sensors: drive at 50+ mph for 10-15 minutes to reset readings. If a TPMS light flashes briefly then stays on, it indicates a system error (e.g., faulty sensor), not just low pressure—have it diagnosed. For indirect TPMS, note that it may not detect gradual pressure loss in all tires simultaneously, so pair it with monthly manual checks. Some vehicles let you view real-time pressure/temperature on the dashboard—use this to spot anomalies (e.g., one tire running hotter than others, a sign of a leak). Advanced TPMS use ensures you catch issues faster than relying on manual checks alone.
