Why does it suddenly show low tire pressure?
2 Answers
Sudden low tire pressure warnings may occur due to: Tire pressure imbalance: When one tire has significantly lower pressure, high-speed driving increases tire temperature and pressure. In this case, promptly stop to rest or replace with a spare tire. Slow air leakage: Use a tire pressure gauge to check. If pressure is low, inflate the tire and monitor the warning light. Tire maintenance tips: Regular inspection: Frequent checks can prevent hazards like blowouts. Regular cleaning: Remove stones or debris from tread grooves to avoid deformation. Drive cautiously: Never exceed speed limits or road conditions. Reduce speed when turning or approaching potholes.
I suddenly saw the low tire pressure warning while driving, which happened during a business trip. Upon inspection, I found a nail had punctured the right front tire, causing a leak. Sometimes, this can also happen when the weather turns cold, especially in autumn and winter, as cold tire pressure naturally decreases but should rise again after driving. If the warning light suddenly comes on, you need to be cautious—it might indicate the tire has been punctured by a sharp object or the valve core is loose. I’ve also experienced slow leaks due to wheel rim corrosion, leading to a gradual drop in pressure. The best approach is to pull over immediately and use a portable pressure gauge to check the pressure, ensuring it’s within the manufacturer’s recommended range (usually indicated on a label on the door), to avoid further driving that could damage the wheel rim or increase fuel consumption. Regularly checking tire pressure once a month is essential; otherwise, over time, it can affect handling safety and even increase the risk of a blowout.
