What to do if the car tire pressure is too high

Car tire problems are the most common situation. For example, in a car tire shop, tire pressure that is too high or too low is not a good situation. When this situation is found, it is necessary to take some effective measures to adjust it in time to prevent it from causing more serious situations and endangering people's lives. So what should you do when your car tire pressure is too high? Let me introduce it below.

If the tire pressure is high, you can deflate it yourself.

How to do it:

Insert a pointed object (such as a toothpick or a small branch) into the valve mouth, and you can hear the sound of air being released.

It is best to have a tire pressure gauge and gently press on the thimble to deflate, and observe with the tire pressure gauge. If you want to be more precise, buy a tire pressure gauge with a deflation function.

Additional information:

The higher the tire pressure, the more fuel efficient it is from the perspective that high tire pressure reduces the friction area between the tire and the ground, and the friction is reduced, thus saving fuel. The tires of the test car are relatively low in profile, and the increase in tire pressure may not cause a significant change in the contact area between the tire and the ground. However, because the excess vibration releases some kinetic energy, it consumes more fuel than normal tire pressure.

Generally, the air pressure is between 0.5 and 0.7 MPa for high-pressure tires, 0.15 to 0.45 MPa for low-pressure tires, and below 0.15 MPa for ultra-low-pressure tires. However, there is generally no need for ultra-low-pressure tires in daily life.

Nowadays, most tires are low-pressure tires, mainly because low-pressure tires have better elasticity and larger cross-sections, which can increase the contact area between the tire and the road, thereby improving the handling of the car.

The air pressure of low-pressure tires is relatively low, and coupled with the tire's own heat dissipation design, low-pressure tires are less affected by air pressure expansion, which also greatly improves the safety factor of low-pressure tires.

Reasons for excessive tire pressure:

1. The tire is over-inflated.

2. When the weather is hot, the gas expands, causing the pressure to rise.

3. Long-term operation causes friction to generate heat, resulting in high tire pressure.

Kind tips:

The vehicle purchase manual shows:

1. The tire pressure of the vehicle is within the normal range.

2. Normal range of tire pressure when the car is running.

Please drive safely according to the tire pressure requirements in the manual.

Dangers of excessive tire pressure:

1. Excessive tire pressure will reduce the friction and adhesion of the tire, affecting the braking effect and also affecting the life of the tire.

2. Too high tire pressure will reduce the tire's puncture resistance and easily cause a tire blowout.

3. It accelerates the local wear of the pattern in the center of the tire tread, reduces the life of the tire, increases the vibration of the vehicle body, and indirectly affects the life of other parts.

4. Excessive tire pressure will also cause the tire cord to be excessively stretched and deformed, the elasticity of the tire body will decrease, the load on the car during driving will increase, and the rolling resistance will decrease.

5. When encountering sharp objects such as nails and glass on the road, it is easy to pierce into the tire, causing internal cracks and explosions due to the impact, resulting in a tire blowout.
