Why is the tire losing air without finding any punctures?
2 Answers
Tire losing air without finding any punctures is due to leaks at the valve core or the installation point between the valve core and the wheel rim. Below is an introduction to throttle-related content: Function: The throttle controls the air entering the engine. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to generate power. Principle: The principle of the throttle is that in traditional engines, the throttle control mechanism operates via a cable (flexible steel wire) or rod, with one end connected to the accelerator pedal and the other to the throttle linkage plate. Electronic throttles mainly use a throttle position sensor to control the throttle opening angle based on the engine's required energy, thereby regulating the amount of air intake.
Last time I had a slow tire leak but couldn't find any nails, which was particularly annoying. Later I discovered it was due to aging valve stems leaking - when rubber ages, it develops microscopic cracks invisible to the naked eye. Wheel rim deformation is another hidden culprit, like when hitting curbs causes poor sealing between the rim and tire. The most easily overlooked are internal tire damages - you need to remove the tire and inspect against light to find cracks. Recently with colder weather, thermal expansion and contraction triggering tire pressure warnings has become more frequent. If all these areas check out fine, I recommend spraying soapy water over the entire wheel rim and tire sidewall - wherever bubbles appear indicates the leak point, which is much more efficient than dry inspection.
