How to Confirm If the Tire Pressure is Insufficient?
2 Answers
Methods to confirm if the tire pressure is insufficient: 1. If the car has a tire pressure monitoring function, simply check the data on the dashboard. If the tire pressure is low, the dashboard will give a warning; no warning means there is no issue. 2. If the car does not have built-in tire pressure monitoring, you can visually inspect the four tires when stationary to see if they look similar. If a tire appears slightly flat and feels soft when stepped on, it indicates insufficient tire pressure. 3. When tire pressure is low, the ride feels softer over speed bumps or rough roads, and there may be a noticeable tilt when going over bumps. 4. Purchase a tire pressure monitoring device, insert it into the tire valve to read the pressure. Generally, around 2.5 bars is normal, over 3 bars is too hard, and below 2.3 bars is insufficient.
I think the simplest way to confirm insufficient tire pressure is to regularly observe the appearance of the tires, especially checking every morning before driving to see if the tires are noticeably sagging or deformed. If one tire looks much flatter than the others, it's likely due to low pressure. I also pay attention to how the car feels while driving, such as excessive steering wheel vibration or unusually strong bumps when going over speed bumps, as these could be signs of low tire pressure. The most reliable method is to use an inexpensive tire pressure gauge to check monthly—just insert it into the valve stem to get a reading and compare it to the recommended pressure listed on the car door, usually between 30 to 35 PSI for small sedans. If it's low, top it up promptly. Never neglect this habit, as insufficient pressure not only accelerates tire wear but also increases the risk of a blowout. Developing this routine saves money and keeps you safe.
