Can You Still Drive with Unstable Tire Pressure?

If the tire pressure is unstable but not leaking rapidly, you can still drive for a short distance. However, it is recommended to promptly check for issues such as punctures or nails in the tire. Here are potential safety hazards caused by unstable tire pressure: 1. Risk of a blowout. According to a report by the National Highway Traffic Safety Administration (NHTSA), if tire pressure is 25% below the standard value, the chance of a blowout increases threefold; if it is 25% above the standard value, the risk doubles. 2. Reduced braking performance. Overinflated tires decrease the contact area between the tire and the road, reducing friction and lengthening braking distance. 3. Increased fuel consumption. Underinflated tires increase the contact area between the tire and the road, raising friction and resistance, which also leads to higher fuel consumption. 4. Shortened tire lifespan. Overinflated tires cause excessive wear in the center of the tread, while underinflated tires cause excessive wear on the sides, both leading to premature tire failure. Tire pressure reset method: First, turn on the ignition, then press and hold the tire pressure monitoring reset button until you hear a "beep" sound before releasing it. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the dashboard warning light will turn off, completing the tire pressure reset.

I've experienced a similar situation where the tire pressure was unstable, causing the car to shake violently while driving, making it feel like the steering wheel wasn't reliable. This is no small matter—both underinflated and overinflated tires can lead to blowouts or skidding, especially on highways. I once tried driving a short distance with unstable tire pressure and found that fuel consumption skyrocketed, and handling was terrible. My advice is, if you notice unstable tire pressure, don't push through—immediately find a safe place to pull over and check. It could be a slow leak or a damaged valve. Make it a habit to check your tire pressure weekly with a gauge, keeping it at the manufacturer's recommended level. If something goes wrong on the road, it's not just bad for the car but also dangerous. Getting it fixed at a professional shop is the safest bet.

As someone who has driven for many years, I particularly focus on saving money and hassle. If the tire pressure is unstable, don't drive—it may seem minor, but it directly affects tire wear and fuel efficiency. Once, I drove with low tire pressure for a day, and not only did the tire wear out prematurely, but I also spent significantly more on fuel. Causes of abnormal tire pressure may include weather changes or minor damage. I recommend checking the tire pressure gauge after parking; if the reading is significantly off, inflate or repair it. Regularly inspect tire condition during routine maintenance to avoid unexpected expenses. Don't risk it to save a little time—fix it before hitting the road, as it's more economical overall.

I think driving with unstable tire pressure is possible but not advisable. If the pressure fluctuates significantly, it could be due to a nail puncture or temperature effects. In mild cases, driving slowly to a repair shop might be acceptable, but continuous handling will become difficult. When dealing with it myself, I first use a tire pressure gauge to check if it's within the safe range. If not repaired promptly, tire wear accelerates, and you might even lose control. I recommend stopping immediately to inspect it—don't wait until a blowout to regret it.
