What about low fetal pressure in winter?

Pacific Auto Network visually checks whether the tires can continue to drive. If you can, you can drive to the nearest tire repair shop for processing. If it can't be turned on, if there is a car air pump, you can inflate it first and then drive it to the nearest repair shop for repair.

Harm of low tire pressure

1, the fuel consumption will increase.

Ensuring normal tire pressure can reduce fuel consumption by 3.3%. If the tire pressure is reduced by 30%, the fuel consumption will increase by 5%~ 10% when the car is driving at a speed of 40 km/h. As long as a 40PSI tire is missing, the life of this tire will be reduced by 1000 km, and the total fuel consumption of the car will increase by 3%.

2. Tire wear will increase.

When the tire pressure is insufficient, it means that your tire will suffer more wear and tear, which is not conducive to the service life of the tire. From the point of view of tire wear, the tire pressure is too high, and the central part is seriously worn. On the contrary, the edge weight, whether too high or too low, will affect the tire life.

3. A puncture occurs at any time.

The main cause of tire puncture is the increase of tire temperature caused by low air pressure after driving. When the tire pressure is insufficient, the sidewall will deform relatively more during driving, generating too much heat, resulting in tire separation and puncture.

4. The vehicle will be extremely bumpy.

When the tire pressure is insufficient or the tire leaks, the adhesion of the tire decreases when the car is running, but the flat road surface has little effect. Driving on the uneven road surface will cause serious jitter, which can not well alleviate the impact from the ground, can not attenuate the vibration caused by the impact, and affect the ride comfort.

5. The braking function will be weakened.

Low tire pressure makes the tire more easily deformed and greatly increases the rolling resistance. When the tire is fully braked under low tire pressure, the deformation of the tire will make the shoulder or even both sidewalls contact the ground. At this time, it seems that the contact area of the tire with the ground is larger, but in fact, due to the shoulder, the contact between the tread and the ground is not very close, which is also the reason for the poor braking function of the automobile under low tire pressure.
