Why does the Magotan tire pressure alarm activate when the tires appear normal?
1 Answers
The Magotan's tire pressure alarm may activate without visible tire abnormalities due to several reasons: slow air leakage where the leak rate is gradual, often requiring immediate inspection of all four tires when the warning light illuminates; subtle symptoms that may create a false perception of normalcy. System malfunctions or false alarms can occur if the sensors, receiver module, or wiring are damaged, leading to incorrect pressure readings. Prolonged driving increases tire temperature, causing pressure to rise due to thermal expansion and triggering the alarm. Tire pressure monitoring systems (TPMS) automatically track real-time tire pressure during driving, alerting to leaks or underinflation to ensure safety. Three common TPMS types include: Direct TPMS: Uses pressure sensors inside each tire to measure pressure directly, transmitting data wirelessly to a central receiver for display. Alerts activate when pressure drops significantly. Indirect TPMS: Detects underinflation by comparing wheel speeds. A deflated tire's smaller rolling radius increases rotation speed relative to others, calculated to monitor pressure indirectly. Tire Pressure Monitoring System (TPMS) Hybrid: Combines advantages of both systems by equipping two diagonally opposed tires with direct sensors and using a 4-wheel indirect system. More cost-effective than full direct systems, it addresses indirect systems' inability to detect simultaneous multi-tire underinflation but lacks real-time pressure data for all tires.
