Where to Inflate a Car with Insufficient Tire Pressure?
2 Answers
For cars with insufficient tire pressure, you can go to an auto repair shop or a 4S store for inflation, as they are generally equipped with professional inflation equipment. Alternatively, you can carry a portable electric car air pump in your vehicle for convenient on-the-go tire inflation. The inflation pressure should adhere to the manufacturer's recommended value. Precautions for tire inflation: Always use a pressure gauge to check the air pressure to avoid overinflation, which could cause the tire to burst. After stopping the vehicle, wait for the tires to cool down before inflating, as driving increases tire temperature and affects air pressure. Inspect the valve stem; if the valve stem and core do not fit smoothly, have protrusions, depressions, or other defects, it may hinder inflation and pressure measurement. Ensure cleanliness during inflation. The air being pumped in should not contain moisture or oil, as this can deteriorate the inner tube rubber. Do not exceed the standard pressure excessively and then deflate, nor overinflate due to prolonged inability to inflate while out. Overinflation beyond the standard can overextend the cords, reducing their strength and affecting the tire's lifespan. Before inflating, clean any dust off the valve stem and avoid loosening the valve core. After inflation, apply soapy water to the valve stem to check for leaks (small bubbles will form if there's a leak). Also, ensure the valve cap is properly fitted and tightened to prevent dirt from entering the valve. When inflating radial tires, due to their structure, their sinking amount and contact area are larger, often leading to the misconception of underinflation and subsequent overinflation. Conversely, their naturally larger sinking amount and contact area might mistakenly suggest adequate pressure when it's actually insufficient. Always use a standard pressure gauge for accurate measurement. The usage pressure for radial tires should be 0.5–1.5 kg/cm² higher than that of conventional tires.
I've been driving a sedan for several years and often encounter situations with insufficient tire pressure. Usually, I just go to a nearby gas station to handle it. Most gas stations have free or low-cost self-service air pumps, which are simple to operate—just connect the air hose to the tire and inflate. I recommend that car owners develop the habit of regularly checking tire pressure, especially before long trips. Low tire pressure not only increases fuel consumption but may also cause premature tire wear, which isn’t worth the risk. If you're unsure where to find one, you can search for 'tire pressure service' on map apps or ask auto repair shops. Some convenience stores also offer this service, making it convenient and time-saving. Last time, I inflated my tires at a highway service station and grabbed a coffee—it made the trip much smoother. Remember, the standard tire pressure is labeled on the side of the car door—don’t exceed the recommended pressure.
