What are the causes of overinflated tire pressure?
3 Answers
The causes of overinflated tire pressure are: 1. Excessive tire inflation leading to high pressure; 2. Overly hot weather causing gas expansion and increased pressure; 3. Prolonged driving generating friction heat that raises tire pressure; 4. Aging or worn suspension components related to the wheels, resulting in improper tire alignment, uneven wear, higher temperatures, and increased pressure. Effects of overinflated tire pressure: 1. Reduced tire friction and adhesion, affecting braking performance; 2. Steering wheel vibration and deviation, decreasing driving comfort; 3. Accelerated wear on the central tread pattern, shortening tire lifespan; 4. Increased vehicle vibration, indirectly affecting the longevity of other components; 5. Excessive stretching deformation of tire cords, reducing tire elasticity and increasing load during driving; 6. Decreased puncture resistance.
I often find that the main reason for overinflated tires is accidentally adding too much air, such as when filling up at a gas station and not paying close attention to the gauge reading. Additionally, hot weather plays a big role—during summer or after long drives, tire friction generates heat, causing internal pressure to expand and increase. I remember one time inflating the tires in cold weather, only to find the pressure exceeded the limit when it got hot, which scared me into releasing some air immediately. Overinflated tires can lead to faster wear in the center of the tread, a bumpy and uncomfortable ride, and even the risk of a blowout over time. It's a good habit to check the cold tire pressure monthly with a tire pressure gauge to ensure it stays within the recommended range. Don’t overlook this—it has a significant impact on driving safety and comfort.
I think the root cause of overinflated tires is often temperature changes, such as when a car is parked outdoors in the sun and the tires heat up, causing the pressure to rise. Incorrect inflation is also a common issue, sometimes due to using an inaccurate air pump or hastily adding too much air. Another factor is when the vehicle is unloaded, reducing the load, which makes the originally suitable tire pressure appear too high. These situations can reduce the tire's contact area with the road, decreasing grip and increasing the risk of skidding or accidents. This is especially dangerous in rainy conditions or at high speeds. To prevent this, ensure the tires are cool before inflating, refer to the recommended values on the door frame, and maintain appropriate pressure.
