What causes a flat tire in a car? What are the causes of a flat tire in a car

Causes of car puncture: 1. The air pressure is too low; 2. Excessive inflation; 3. Installation error; 4. Failure to carry out good maintenance and maintenance; 5. Tire wear and aging; 6. The side of the tire is bulging and has burst defects; 7. Violent impact. Measures to prevent flat tires in vehicles:

1. Replace tires in time; 2. Do a good job of four-wheel alignment and dynamic balance of tires; 3. Front and rear tire transposition; 4. Maintain normal tire pressure; 5. Do not speed. How to deal with a flat tire of a vehicle: 1. Hold the steering wheel tightly, adjust the front of the car, and move gently; 2. Don't hit the steering wheel repeatedly, don't slam on the brakes sharply, and then hit the steering wheel after the vehicle speed gradually slows down; 3. Erect a warning triangle behind the car to prevent secondary accidents.

There are many reasons for punctures, the main ones are as follows: 1 Tire pressure is too low Some drivers often do not reach the standard air pressure when inflating because they are afraid of "puncture", which is very wrong. Because the tire pressure is too low, the sinking amount of the wheel increases, the radial deformation increases, the friction between the tread and the ground increases, the rolling resistance rises, and the internal stress of the carcass also rises, resulting in a sharp increase in the temperature of the carcass, the softening of the tread rubber, and the acceleration of aging, which causes the local delamination of the carcass and the aggravation of the wear of the tread.

In this case, if the car is driving at high speed on the highway again, the above reaction of the tires will be accelerated, and there is a high risk of a puncture. 2 Over-inflated tires In order to increase the cargo capacity of the car, some drivers like to exceed the standard air pressure of the tires when inflating, but they don't know that this accelerates the wear rate of the tires, thus increasing the possibility of a puncture. Because the tire pressure is too high, the tension of the carcass cord increases, so that the fatigue process of the cord accelerates, especially when over-inflated and overloaded and speeding, the internal stress of the cord is increased, the tire temperature rises rapidly, the rubber aging speed accelerates, and the fatigue strength decreases, so that the tread ** is seriously worn and the sidewall pattern is jagged and worn, and the cord layer is broken, which causes a puncture.

3 Tire Installation Error (1) The wheels are unbalanced. Some drivers when replacing tires, do not carry out dynamic balance test on the spare tire to be replaced, if the wheel is unbalanced, then, because the mass distribution of the wheel facing each part is uneven, when the wheel rotates, under the action of centrifugal force, the wheel rotation plane will produce a huge impact force, so that the wheel jumps and swings, thereby increasing the wear rate of the tire, makes the cord layer subject to a periodic impact load, reduces the fatigue strength of the cord, especially in 100km At high speeds above h, the wear caused by the imbalance of the wheels is very intense, which eventually leads to a puncture. (2) Improper alignment of the front wheels.

The front wheels of the car play a steering role, and once the front wheels have a puncture, the car will lose its ability to steer, causing serious traffic accidents. Some drivers do not accurately position the camber angle and toe of the wheel when replacing the front wheel tire, so that when driving, it will make the inner or outer side of the car crown wear very seriously, if it is not adjusted in time, driving for a long time, so that this wear continues to intensify, it is easy to cause a puncture. 4 Lack of necessary maintenance of tires Some drivers only care about economic interests, and forget the regular maintenance of the car, do not transposition and maintenance of the tires, so that the tires will appear uneven wear, easy to form weak spots, resulting in punctures.

In addition, if the stones trapped in the tire pattern are not removed in time, it will also accelerate the wear of the tire and lead to a puncture.

What are the causes of a flat tire in a carThe main factors that lead to a puncture are as follows: 1. Long-term driving of tires is easy to lead to punctures; 2. Puncture caused by excessive tire pressure or excessive wear caused by excessive wear caused by excessive tire pressure or suspension problems; 3. Puncture caused by tire aging and cracking; 4. Puncture caused by tire wear to the limit and not replaced in time; 5. Puncture caused by the tire being scratched by a foreign object during driving; Tire maintenance precautions:

1. Keep the tire pressure normal 2. Pay attention to the degree of tire pattern wear and whether there is eccentric wear 3. Check whether the tire has aging and cracking trend 4. Properly use tire maintenance products to maintain the tire.

A flat tire in a car may be caused by excessive pressure inside the tire due to driving for too long, or it may be too hot and the temperature inside the tire is too high, or it may be that it has touched a sharp object.

Causes of punctures There are many reasons for punctures, the main ones are the following: 1Tire pressure is too low Some drivers often do not reach the standard air pressure when inflating because they are afraid of "puncture".

Causes of punctures There are many reasons for punctures, the main ones are the following: 1Tire pressure is too low Some drivers often do not reach the standard air pressure when inflating because they are afraid of "puncture".

There are several reasons for a car puncture, such as too high or low tire pressure, sharp objects when driving, and tires that are used for too long.

Excessive tire wear:

This is easier to understand, when the tire is worn excessively, the rubber can withstand less pressure, when the tire temperature rises for a long time, the tire pressure is too high, at this time it is easy to have a puncture, especially some tires that have been repaired many times, the probability of a puncture will also increase. Tires with damaged sidewalls also tend to increase the chance of a puncture. Therefore, when the tires are worn to the marker line, they need to be replaced.

The tire must have several necessary factors before it will have a puncture; Never get a flat tire for no reason, it is easy to cause a puncture: the highway. Speeding.

Overload. Tires are worn and aged. Air pressure is too high or too low.

The tires are of poor quality. If you are driving on the highway and your vehicle has a flat tire.

There are many reasons for a car puncture, which can be too high tire pressure, aging tires, or high tire temperature, which can cause a car to have a puncture.

Excessive wear, aging, cracking and trauma of tires are also one of the causes of punctures, such as the pattern block after long-term friction with the ground, the pattern gradually becomes shallower, when the wear to replace the mark should be stopped immediately.

1.There are many reasons why a car can have a flat tire:

Low tire pressure,. Tires are overinflated,. Improper tire installation. Lack of necessary tire maintenance.

There must be several necessary factors for a flat tire to have before it will be punctured; Never get a flat tire for no reason, it is easy to cause a puncture: the highway. Speeding. Overload. Tires are worn and aged.

丨 What is the reason for a car puncture, on the one hand, the reason for the tire, on the other hand, the reason for the ground There is also a profit effect that does not protect the effect generated during use.

You should check if the tires of your car have been punctured at this time. And after that? Check if the air pressure is too low or over-inflated, and it is possible to install it incorrectly.

The air pressure is too low; over-inflation;

installation error; Failure to perform good maintenance and upkeep;

Tires are worn and aged.

The side of the tire is bulging and has a burst defect;

Violent impact.

Front tire puncture: The car will deviate to the side of the puncture, at this time the driver needs to hold the steering wheel with both hands, grasp the direction of progress, slow down the accelerator, and then use the point brake to slow down the vehicle.

Rear tire puncture: The rear tire puncture usually does not lose control, at this time, you can repeatedly lightly press the brakes and slowly stop the car in the form of point brakes. Note: In the case of a puncture, remember not to suddenly collect the oil and slam on the brakes, because this operation can easily cause the vehicle to flick or even spin or overturn.

The air pressure is too high, the load is excessive, the inner tube is aging, the inner and outer tubes are injured, the outer tubes are foreign bodies, and the inner tubes are damaged by external forces.

Easy to cause punctures: highways. Speeding.

Overload. Tires are worn and aged. Air pressure is too high or too low.

The tires are of poor quality. If you have a flat tire while driving on the highway, you should hold the steering wheel tightly, look at the rearview mirror, transfer the vehicle to the right, and try to move to the hard shoulder on the right side of the road to be safer, and do not occupy the leftmost overtaking belt, which is more dangerous.

Car tires are also prone to punctures due to oil corrosion. This is because car tires are made of rubber, and their chemical composition is organic substances, which are easily soluble in organic solvents such as gasoline and motor oil, which are corroded, and then cracks and cracks. Such tires cannot withstand normal air pressure and do not have normal load capacity, and are extremely prone to punctures when driving on the road.

1. Caused by human factors.

1. Operation error.

Usually, when parking or emergency avoiding obstacles, it is easy to have a puncture, especially when avoiding obstacles and driving at high speeds, it is necessary to take correct actions quickly to avoid personal injury.

2. The tire pressure is too high.

The tire pressure is too high, so that the contact area between the tire and the ground is reduced, the pressure on the tire per unit area increases, the wear is intensified, and the tire is prone to puncture during driving.

3. Inferior tires or counterfeit products.

The use of inferior tires or counterfeit products refers to the use of inferior rubber tires to pretend to be big brands to deceive consumers, inferior rubber is not as good as high-quality rubber, and it will directly affect driving comfort and safety when used. If you buy an inferior tire by mistake and replace it for the normal life of the tire, it is easy to get a puncture.

4. Intense driving.

Conventional production vehicles often start sharply when the tires are not upgraded, which can easily lead to uneven tire thickness, which can lead to punctures.

5. The internal injury was not replaced in time.

Car tires will inevitably be punctured or bruised if they are used for too long, so they must be replaced and repaired in time, as these internal injuries may lead to a puncture of the vehicle while driving.

6. Excessive belief in the propaganda function of tires.

Do not believe 100% of the explosion-proof propaganda of verbal propaganda. Even if the puncture tire is not necessarily not bursting, but the tire wall is relatively thick, and it can support the vehicle to continue driving at low speed after a puncture.

Second, caused by technical factors.

1. Poor heat dissipation of the hub.

Due to heat transfer, vacuum heat conduction in the tire cavity, heat accumulation and other comprehensive heat sources caused by puncture can not be ignored, which is also the main reason for the puncture of new tires and new wheels of new cars.

2. Insufficient tire pressure for high-speed driving.

The tire bursts when it is not punctured and bruised, the tire pressure is insufficient, and the ring wear or friction occurs due to the bumps compressing the tire cavity during driving, and the burst occurs from the inside out.

3. Exceeding the speed limit of the tire.

91V) 91 - 615 kg for a single load, V- for a permissible maximum speed of 240 km/h. Both overweight and speeding are definitely flat tires.

4. Fill with inferior heat-blocking gas or unknown inert gas.

It is often said that nitrogen filling or filling compound nitrogen, etc., the air itself contains 78% nitrogen, if the tire is not vacuumed during the filling process, it is equal to white charging.

In high-speed driving, if the rear tire of the car bursts, the car is just shaking up and down, the problem is not very big, the car steering wheel can be controlled, and the car tilt is not bad, as long as you find a way to stop the car slowly. If it is the front wheel, there is more trouble, not only the car will tremble, tilt, and the steering wheel will also be suddenly pulled to the side of the puncture by a limited force, a little negligence, not control the steering wheel, the car will turn backwards 360 degrees and cause trouble. At this time, if you press the brakes due to nervousness, the consequences are even more unimaginable.

Because after the tire is deflated, the combination with the steel rim becomes very loose, and the part of the tire that touches the road surface will be deformed and separated from the steel rim, plus stepping on the brake, the wheel on the side of the puncture tire will be reduced due to the high resistance, and the speed will be reduced, which is easy to brake, resulting in the complete separation of the steel rim and the tire. The other wheels are correspondingly less easy to brake and may have to move on, as if a running person is suddenly forced to kneel down with one foot, causing the car to roll over. Therefore, if a puncture occurs during high-speed driving, especially when the front wheel bursts, the brakes should never be pressed.

Instead, keep your hands on the steering wheel, try to control the direction of travel, and release the accelerator to let the car slow down slowly. When the speed of the car has completely decreased, operate the steering wheel to stop in a safe place on the side of the road, change the tires, and move forward again. The main cause of a puncture in a car at high speed is often over-inflated, which we have already introduced, in addition to this, it can also be due to tire cracks, peeling and other damage, or due to unclean roads, tires hit hard things and other accidents.

Therefore, before driving on the highway, you should carefully check the tires, replenish the gas, and be mentally prepared to deal with unexpected situations. In case of a puncture, we must grasp the steering wheel at any time and be vigilant at all times, so that we can be calm and calm at the critical moment of a puncture, better control the direction and ensure safety. It's a matter of the individual's responsiveness.

A flat tire in a car is too dangerous, so what are the causes of a puncture, there are three reasons.
