As the weather gets colder, have you found that in the winter, our tires are not so good, obviously the weather is cold, I put the tire tire pressure to 2.5, but the temperature continues to fall, it is 2.3/2.2, if after two days it temperature rises a little, but it can not reach 2.5, so if we long-term low tire pressure driving on our car how much impact? Today, Brother Meow will talk to you.
Like this car it B pillar above the indicated recommended tire pressure value is 2.3, after the temperature drops it is basically in 2.1/2.2, that is, sometimes the temperature is low it will reach 2.0 this range wandering, but in this case although it says 2.0, basically we tire pressure monitoring It will not alarm, because according to my experience, like this nominal 2.3 it will reach 1.9/1.8 It will alarm, this time in fact, when you usually drive, you may be below its nominal tire pressure value for a long time.
In fact, it means that if you don't replenish the air in winter, its tire is driven below its nominal tire pressure value for a long time, so how much impact does it have on our car? First of all, the first point, if the tire pressure is too low, I said low is like the nominal 2.3, if to 1.8 speed is relatively fast, run high speed, then if its air pressure is very low for a long time, it may lead to standing wave deformation of the tire. That is to say, the tire wall of the tire, due to the squeeze of the tire pressure is too low, it is easy to cause a puncture.
Punctures are punctures caused by standing wave deformation of tires caused by low tire pressure. The second point you can see, the tire is obviously in contact with the ground is relatively large, in this case, it will cause our tire rolling resistance is too large, that is, the tire in the rolling due to its contact with the ground area is large, if the tire resistance is too large, the most direct performance is that when you drive this car, it feels not so light, the impact is the fuel consumption of our car.
That is to say, your fuel consumption will be higher than the normal tire pressure of the tire, which is the second effect. The third effect, if you say that the long-term low tire pressure driving, because the tire pressure is insufficient, so it will lead to tire wear, the middle part of the tire pressure can not be supported, not so prominent, so the two sides wear more, more severe, so the abnormal wear of the tire is grinding, or grinding more severely, or grinding more severely.
Such a way will lead to tire scrapping in advance, the above three points are the tire pressure of the tire for a long time, lower than the nominal tire pressure for our car is a very practical impact. But some of the effects here are very important, some are not important, for example, the first point affects safety, if you often run high speed, it is recommended that you better hit your tire pressure to your nominal tire pressure value, and even the nominal tire pressure value to go up to the top is not a big problem, because the nominal tire pressure value is actually a more conservative, that is, a more safe plus comfortable tire pressure value, in fact, the tire pressure value Its fuel consumption is not very economical.
It's just that the comfort will be better, if you want fuel consumption to be more economical and run lighter, it is recommended that it can be slightly higher than the nominal tire pressure value, For example, the nominal tire pressure value of 2.3 you can hit 2.5, but if you are worried about the tire due to insufficient tire pressure, resulting in abnormal wear, then this, from my personal actual experience, we do not have to worry too much, because the vast majority of family cars you are basically more than 10,000 kilometers a year less than 20,000 kilometers, normal family cars basically your tires can reach 80,000 kilometers 100,000 kilometers this range.
So according to the normal mileage to calculate, basically your tires run to 5 years and 6 years when you should also change according to the age, this time in fact, your tires are far from wear to the wear marks that should be changed, the actual tire looks like the pattern is still very good, but the age has arrived, the rubber has hardened, in order to replace it safely, so in this piece, there is no need to worry too much, due to the lack of tire tire pressure abnormal wear leads to tire scrapping in advance.
What is more worrying is the lack of tire pressure, if you run at high speed, it will cause the tire to burst the safety hazards brought to us. So in the winter, if the tire pressure is lower than our nominal tire pressure for a long time, if you say that you don't care so much about fuel consumption, and you are basically driving urban cars in the urban area, this piece is not so much to worry about, if you say that running at high speed, then you must make up for the tire pressure in time, at least to your nominal tire pressure.
If your car is this kind of indirect tire pressure monitoring, it does not display data, and it only has a reminder when the tire pressure of a tire is insufficient. For example, when driving in the morning, due to the relatively low temperature, this time may have this prompt, but after you drive for a period of time to let the temperature of the tire rise, it tire pressure to go to the top a little hint it will disappear, if it continues not to disappear, it is recommended that you can also make up for the tire pressure slightly.
So winter car, if you say that the long-term lower than the standard tire pressure driving, in fact, in addition to your running high-speed impact on safety is a little larger, other effects at most is that the fuel consumption is slightly higher, and then the tire may appear slightly abnormal wear, but these effects will not affect our safety, if you can accept it, the tire pressure is slightly lower, and the car is more comfortable to drive.
