What to Do When the Dashboard Shows Low Tire Pressure?
2 Answers
If no damage is visible, you can simply inflate the tire to the normal pressure and reset the tire pressure system. If upon inspection you find that the tire has been punctured, promptly drive to a tire shop to have it repaired before reinflating. If the low tire pressure warning reappears after inflation without any visible puncture, it may be due to air leakage caused by a deformed wheel rim. It is advisable to check the wheel rim and replace it if necessary. When inflating tires, pay attention to the following points: Always use a pressure gauge to check the tire pressure to avoid overinflation, which can lead to tire bursts. After stopping the vehicle, wait for the tires to cool down before inflating, as driving increases tire temperature, affecting pressure readings. Inspect the valve stem. If the valve stem and core are not properly aligned, have protrusions, depressions, or other defects, it may hinder inflation and pressure measurement. Ensure cleanliness during inflation. The air used should not contain moisture or oil to prevent deterioration of the inner tube rubber. Do not exceed the standard pressure excessively and then release air, nor overinflate due to prolonged inability to inflate while traveling. Excessive pressure can overstretch the tire cords, reducing their strength and shortening the tire's lifespan. Before inflating, clean any dust off the valve stem and avoid loosening the valve core. After inflation, apply soapy water (or saliva) to the valve stem to check for leaks (bubbles will form if there's a leak). Ensure the valve cap is securely fastened to prevent dirt from entering the valve stem.
When the dashboard indicates low tire pressure, I always immediately drive the car to a safe place to park, such as the roadside or a gas station. After getting out, I squat down and carefully inspect each tire to see if there are any nails or obvious cracks causing air leakage. I then use the onboard tire pressure gauge to measure and confirm which tire has the issue. If the pressure is below the recommended value on the door label, I use a portable air pump to inflate it to the normal level. After inflating, I start the car to see if the warning light is still on. If it remains, it might indicate a hidden leak. In such cases, I never force the car to drive to avoid tire deformation, damage, or loss of control leading to accidents. I have developed a habit of checking tire pressure at least once a month, and more frequently in winter because cold air can cause tire pressure to drop. This practice not only ensures safety but also saves fuel and extends tire life, making it both cost-effective and reassuring.
