Is It Necessary To Buy Car Air Pump

In the end, there is no need to buy the car air pump, when the tire pressure detection system of our car detects that it is too low, we can use the air pump to pump in time, if it is too high, it will be deflated to ensure that the tire pressure can be in a specified range of values. So I think it is necessary to buy car air pump, for some often long-distance business trips or play owners, not to mention, at high speed if found tire pressure is not normal, can be handled in time to avoid traffic accidents. Let's talk about the impact of high or low tire pressure.

Effects of high tire pressure:

First of all, too high tire pressure will harden the tire, resulting in smaller contact area with the ground, which has a direct impact on the braking effect. If it is tied to the more pointed things, the possibility of a flat tire relative to the normal tire pressure will be relatively large, if at high speed is unthinkable. The second is to speed up the middle of the tread wear, so the tire replacement cycle may have to shorten.

Effects of low tire pressure:

Because the tire pressure is too low will make the tire soft and increase the size, resulting in the increase of the contact area with the ground, that is, the friction will increase a lot, not only lead to car fuel consumption rise, but also speed up tread and tread wear, to know that the tire side and tread do not do so strong, long-term down it is likely to crack, leading to a tire.
