What Causes Car Tire Pressure Warning in Winter?
2 Answers
During winter driving, it is normal for tire pressure readings to be abnormal due to lower temperatures. The methods for detecting tire pressure are as follows: Direct Tire Pressure Monitoring: Connected tire pressure monitoring devices directly measure the tire pressure. They use wireless transmitters to send pressure information from inside the tire to a central receiving module, which then displays the tire pressure data. When the tire pressure is too low or there is a leak, the system will automatically issue a warning. Indirect Tire Pressure Monitoring: The working principle is that when the pressure in one tire decreases, it causes that tire to rotate faster than the other wheels. Intelligent Tire Monitoring System (TPMS): It combines the advantages of the two systems mentioned above. It is equipped with a direct sensor on two diagonally opposite tires and a four-wheel indirect system. Compared to a direct system, this composite system can reduce costs and overcome the drawback of indirect systems, which cannot detect low pressure in multiple tires simultaneously.
When I first started driving, I often saw the tire pressure warning light come on when starting the car on cold winter mornings, which made me quite anxious. Later, as I gained more experience, I understood that in cold weather, the low temperature causes the air to contract, leading to a drop in tire pressure. The tire pressure monitoring system is very sensitive and will alert you as soon as the pressure falls below the set value. It's not just in winter—you should always be cautious, as tire leaks or sensor malfunctions can worsen the issue. I recommend checking the tire pressure more often, especially during seasonal changes. Simply topping up the air at a reliable gas station can solve the problem, so there's no need to worry too much. Remember to maintain the recommended tire pressure for both safety and fuel efficiency, as low pressure can increase braking distance and affect driving stability. It's best to develop a habit of checking monthly, bringing along the manual to reference the manufacturer's recommended values.
