Why is the probability of low tire pressure explosion?

Tire pressure is too low，The area of ​​contact with the ground will become larger，On the one hand, it will increase the friction coefficient of the tire and the ground，On the other hand, when the tire is rolled below，The curtain of the curtain in the tire side rubber curtain is too much compressed，When the tire rolls to the top，The curtain line must be restored to the original position under the action of elasticity and tension，This will deform the internal curtain layer、Accelerate fatigue，Severe structural injury caused by severe cases。

This repeated deformation，Straight is that the owners have played with the wire with my hands when they were young，Iron wire will heat up after repeated movement，The intensity will also soften，easier to break，The carcass curtain line of the tire inner curtain layer is also the same.。Tire temperature is higher when driving，will accelerate the deformation of the cable curtain line of the tire inner curtain layer，Unreveal damage occurs in the tire structure，If you can't hold it, you will explode。

When the tire pressure is high，Overall rigid enhancement，Although there will be no friction and excessive flexion，But when I encounter severe bumps、High temperature、The situation of a drum or burst of tires when the sharp object collides。seabet app

Subvert! High tire pressure may not save fuel

Many people feel that high tire pressure is more fuel -efficient than normal tire pressure，seabet myTheoretically speaking，Right! Because the area of ​​high tires and ground friction between tire pressure is generally believed to be reduced，Reduced friction and save fuel。Xiaobian has also seen the actual measurement of whether the tire pressure saves fuel.，Conclusion is high tire pressure saving。But this conclusion is contrary to Xiaobian's daily car perception。

This，According to netizens test。He drove a 2010 Junyue 2.4L luxury version，Test the vehicle with normal tire pressure 2.5BAR and high tire pressure 3.1Bar on the same line for a circle，Selected routes: The round -trip route from the Linhai Highway Toll Station from Shanghai to Lingang New City，round -trip is about 110km，Among them, about 90km unblocked high -speed roads，About 20km universal normal section。

To avoid interference caused by traffic vehicles to fuel consumption，Selected test time Select the non -peak period of working days，The load of the vehicle from two fuel consumption test vehicles is the same、drive from the same person，No air conditioning and seat heating at the whole process。Errors caused by minimizing the depth of the accelerator，Speed ​​cruise on high speed，Set the cruise speed of 100km/h。

But the test results are completely opposite to common sense: high tire pressure (3.1BAR) 100 kilometers of fuel consumption is 8.41L，Normal tire pressure (2.5bar) 100 kilometers per 100 kilometers 8.26L。

The editor checked the information and found a possible explanation: the tire of the test car is relatively low，It does not reduce too much contact interview，At the same time，Tire pressure is too high to cause the tire to produce excess jump，Release some kinetic energy，To maintain speed，The engine will do more merit，So it cost more oil than under normal tire pressure。

Of course, 0.15 L/KM's fuel consumption difference may be one or less red and green lights.，Even the wind and wind will cause this difference。But no matter which aspect of it is understood，Through this test, you can get a conclusion that is not counted: high tire pressure may not be fuel -saving，At least the fuel consumption of at least the fuel consumption of normal tire pressure is not much different。

Usually standard inflatable pressure of tires 2.2-2.8bar Between (cold tire pressure) Correct tire inflation pressure。Under air load，Ordinary cars are generally 2.3 Bar About, the off -road is 2.5Bar.

Tire pressure is too high or too low will cause tire life to shorten.

High tire pressure:If the tire gas pressure is too high，Tire rigidity increase，Deformation and grounding area decrease，First, it will cause the pressure of the unit in the middle of the tire to increase the pressure，Eraded，Dynamic phenomenon of the central wear of the tire crown，Affecting comfort and reducing tire life; at the same time，It will also reduce the grip of the tire (especially on the slippery road，It will affect the braking distance)，It will also cause the wear speed of the tire to accelerate，Lear the tire abnormally。

Low tire pressure:opposite to the high -tire pressure wear center，Tire pressure is too low，Then the tire crown shrinks，will cause wear on both sides of the tire。And，Low tire pressure and flat ratio are small.，When the tire side is squeezed，Direct impact of wheels and ground，It is also easy to cause breaks of the curtain layer line，Either burst tire，Either a drum。

Tire pressure，In safety、Comfort、Economics also has some effects，Appropriate tire pressure，Not only can ensure driving safety，It can also bring a more comfortable driving experience。

32%of high -speed accident margins

According to statistics from the traffic management department，46%of the traffic accident on the highway every year is caused by a tire failure，Among them, 70%，that is, 32%of traffic accidents occur due to explosive tires。Generally speaking，Tire trauma、Tire aging、Excessive wear、Abnormal tire pressure is the four culprits that cause tires，The first three can be seen through the appearance，Only tire pressure is basically impossible to visual inspection。

So，A better car now，Bring tire pressure monitoring; without tire pressure monitoring，Many car owners will also choose to install，Intelligent monitoring tire pressure abnormal conditions，Once there are abnormalities, it will be reminded，Avoid dangerous occurrence。

If the car has no tire pressure monitoring, you can also seeTooth measurement method, kick testMethod for self -inspection.

Mainly to see if the tire pressure is normal with the naked eye，Generally, the grounding area of ​​4-5 teeth can be regarded as normal tire pressure。

Foot kick measurement method

Generally, it is difficult for the general owner to kick alone to determine whether the tire tire pressure is at normal level，Here the editor dump a wave of data。

But we still recommend that you use scientific instruments to monitor，Avoid judgment errors。Summer is a high -incidence season，We can't predict the danger，But you can use scientific methods to prevent problems before it happens，Reduce travel risk，Guarantee the security of yourself and your family。(Photo is derived from the Internet，If you involve the copyright, please contact delete)
