What to Do If Car Tire Pressure Is Too High?
2 Answers
To address high tire pressure in a car: Simply press the air release valve while monitoring the numbers on the tire pressure gauge to maintain normal pressure. The hazards of high tire pressure include: 1. Reduced tire friction and adhesion, affecting braking performance and tire lifespan; 2. Decreased puncture resistance, increasing the risk of blowouts; 3. Accelerated wear on the central tread pattern, shortening tire life, increasing vehicle vibration, and affecting the lifespan of other components; 4. Excessive stretching of tire cords, reducing tire elasticity, increasing the load on the car while driving, and lowering puncture resistance; 5. Increased susceptibility to punctures from nails, glass, or other sharp objects on the road, leading to internal cracks, bursts, and blowouts upon impact.
In my decades of driving experience, encountering high tire pressure is quite common, especially when the weather turns cold and readings may be falsely high. I first use the onboard tire pressure gauge or find a meter to confirm if it's indeed too high, then pull over to a safe spot, open the door to check the standard values on the side label or manual (e.g., front tires 230 kPa, rear tires 250 kPa), and slowly release air to reach that level. Excessively high pressure causes faster wear in the middle of the tire, increases braking distance, and raises the risk of a blowout, compromising safety. I make it a habit to check weekly, and using a tire pressure monitoring app on my phone makes it even more convenient, with reminders about seasonal changes. In short, addressing it early brings peace of mind—don’t wait until an accident happens to regret it.
