What does tire air leakage mean?
2 Answers
Tire air leakage means that after a tire is punctured, the internal air pressure leaks into the tire's nylon cords and steel wire layers. Even after the inner side of the tire is repaired, the air pressure in the nylon cords seeps out from the punctured spot and disappears after a period of time. Tire lifespan: The wear lifespan of a tire is 30,000 to 50,000 kilometers. If the tire hasn't reached the wear limit or mileage but has been in use for 5 years or has developed numerous cracks on the sidewalls, it needs to be replaced. Functions of tires: Tires transmit driving force, braking force, and steering force to enable vehicle operation; they support the vehicle's load; and they reduce and absorb vibrations and impacts during driving, preventing severe vibrations from damaging automotive components.
I've been driving for over a decade, and 'tire air seepage' simply means slow tire air leakage. To put it plainly, it's when the air gradually leaks out rather than a sudden blowout. My previous car experienced this – for a while the tire pressure kept dropping, and after inspection we found scratches on the tire sidewall plus aging valve stems causing gradual air loss. This issue is quite annoying; you can feel increased fuel consumption while driving, and the steering feels floatier than usual. I recommend regularly checking tire pressure yourself with a gauge, or spraying soapy water on tires to locate air bubbles indicating leaks. Once identified, promptly visit a professional shop for tire repair or valve stem replacement – don't delay as it may damage other components. Safety comes first. Also, avoiding gravel roads or areas with sharp objects can prevent this. In summary, while tire air seepage seems minor, its impact isn't – never take it lightly.
