What are the causes of tire pressure loss in sedans?
2 Answers
Generally, there are three reasons for tire pressure loss. The first is related to load capacity. The second is related to seasons. The third is related to tire specifications. Meaning of tire pressure loss: It indicates that the tire pressure is too low and requires immediate inspection. Insufficient tire pressure can lead to increased fuel consumption, uneven tire wear concentrated on both sides, and in severe cases, may cause standing wave phenomenon, directly increasing the risk of tire blowout. Recommended tire pressure values: These should be determined based on the position of the tires on the vehicle, as weight distribution varies. Recommended values differ between vehicles and between half-load and full-load conditions, so it's essential to consult the vehicle manufacturer. Additionally, winter's lower temperatures and summer's higher temperatures can affect measured tire pressure readings.
I've been driving for over a decade and have encountered flat tires several times. The most common cause is definitely punctures from nails – those little road nails are hard to avoid. Also, tire pressure drops particularly fast in cold weather, and aging plastic valve cores can leak too. I remember one time when the wheel rim was deformed, the tire slowly leaked air through the edge seam – it was fine when I left in the morning, but the warning light came on halfway. Sometimes the leak continues if the repair wasn't done properly by the mechanic, and small cracks in the tire rubber are also potential hazards. Whenever the tire pressure warning comes on, I drive straight to a repair shop for inspection. Replacing a new valve core only costs a few bucks – definitely not worth toughing it out.
