What does tire pressure monitoring alarm indicate?

[VonBrooke]

Tire pressure alarm indicates that there is excessive deviation in pressure among the four tires or insufficient inflation, suggesting an issue with the vehicle's tire pressure that requires immediate inspection. Possible causes include: 1. Air leakage: The tire pressure monitoring light may illuminate due to a puncture causing slow air leakage. In such cases, it might be difficult to immediately identify which tire is affected. Use a tire pressure gauge to measure the pressure (recommended: front tires 2.3, rear tires 2.5). If pressure is low, inflate accordingly and then monitor the warning light. If it illuminates again after a few days, remove the tire for thorough inspection. 2. High temperature: The tire pressure monitoring light may also indicate overinflation. Prolonged driving with low tire pressure can trigger the warning light, typically occurring when a tire's pressure is too low, causing increased temperature during high-speed operation which subsequently raises the pressure. In such situations, promptly pull over to rest or replace with the spare tire.
