A flat tire in a car is dangerous, so is it more dangerous to puncture a front tire or a rear tire?

It is more dangerous after a puncture, because the vehicle will lose its balance after a puncture, if it is in the case of high-speed driving, it is easy to have a relatively large accident, especially on the highway, and the general car will cause some major accidents after a puncture. So when we drive, if we encounter a flat tire in a car, don't panic, we must hold the steering wheel tightly.

A puncture on the front steering wheel is more dangerous than a puncture on the rear wheel, because a puncture on the front steering wheel can easily cause the direction to lose control, and a puncture on the left front wheel is more dangerous than a puncture on the right front wheel! Because many drivers like to occupy the left lane, the left front wheel has a flat tire, then the car will immediately hit the protective barrier, and then there is a possibility of rolling. The right front wheel had a puncture, because the car was far away from the right fence and there was a cushioned distance that could be saved.

A punctured left rear tire will deviate to the left, but it is not as urgent as a puncture on the left front wheel, and the direction is completely controllable if it should be done properly. The right rear tire burst will deviate to the right, and it can drive to the right lane and stop in the emergency lane, so it is the least dangerous.

Generally speaking, it is more dangerous to blow the front tire, because it is easy to lose control of the car.

The rear wheels are dangerous.

Under normal circumstances, if the front wheel bursts, the left front wheel will deviate to the left, and the right front wheel will deviate to the right; The car with a flat rear tire will lose steering force and will suddenly oversteer, which is commonly referred to as "tail flicking". When the "tail flicking" situation is serious, the car will spin like in film and television dramas or live racing broadcasts.

Therefore, comparatively speaking, in the case of low-speed progress, the front wheel puncture is more dangerous than the rear wheel; At high speeds, the danger from a puncture at the rear wheel is even more severe.

For example, the right rear wheel puncture, first the puncture wheel resistance increases by about 30 times, causing the car to be subjected to a clockwise side deviation moment, the side deviation moment makes the car yaw to the right side, and the side deviation moment simultaneously produces a transverse force directed to the inside of the puncture wheel, so that the rear part of the car is subjected to the lateral force of sliding to the inside of the puncture.

A puncture at the front wheel is more dangerous because the front wheel is not only the power wheel (most family cars), but also the steering wheelAt the moment of a puncture of the front wheel, there will be a more obvious direction shift. But don't jerk the wheel just because you've shifted direction. When the car is at high speed, it is very easy to roll over if you slam the direction.

The correct way to do this is: the steering wheel must be tightened, while stabilizing the direction, slowly return the direction to the right, lightly press the brakes, wait for the speed to drop down, and stop in the emergency lane.

The danger of a rear tire burst is less than that of the front wheel, and the main thing is to grasp the direction. Then repeatedly press the brakes, because the center of gravity of the car will move forward at the same time as braking, so that the force on the front wheels will increase, which can reduce the pressure on the rear wheels, but remember, you still can't press the brake pedal hard, and you can't brake urgently.

Car tire precautions.

1. Daily tire pressure check to avoid tire pressure too high or too low. Because the tire pressure is too high in high-speed operation may be unable to withstand the excessive expansion pressure and the danger of puncture, the tire pressure is too low in the process of driving due to the unevenness of the road surface caused by the excessive expansion of the tire, so that the tire is in a long-term fatigue period, accelerate the tire aging, so should be in accordance with the manufacturer's requirements to maintain the standard air pressure of the tire, including the spare tire pressure.

2. Do tire rotation regularly. It is to cross the front and rear tires, (left front - right rear, right front - left rear) because the car is generally front-wheel drive, then as a driving wheel, its tire wear is more serious than the driven wheel, and because the front wheel is a steering wheel, the sliding friction is increased on the basis of rolling friction, which makes the front wheel of the car more serious than the rear wheel wear.

A flat tire is extremely dangerous in any situation, whether it is a front or rear tire blowout; Under normal circumstances, if the front wheel bursts, the left front wheel will deviate to the left, and the right front wheel will deviate to the right; The car with a flat rear tire will lose steering force and will suddenly oversteer, which is commonly referred to as "tail flicking".

When the "tail flicking" situation is serious, the car will spin like in film and television dramas or live racing broadcasts.

In the case of low-speed progress, the front wheel is more dangerous than the rear wheel; In the case of high-speed driving, the danger caused by the puncture of the rear wheel will be more serious, the front-wheel drive or the rear-wheel drive, the driving wheel puncture will appear in the effect of the two driving wheels There will be a sudden change, the puncture wheel loses grip, the other side of the normal drive, will definitely push the car to deviate or swing, there is a puncture, must stabilize the direction, slow down and stop.

A flat tire on the rear wheel is more dangerous than a flat tire on the front wheel!! A flat tire is extremely dangerous in any situation.

Comparatively, a puncture at the front wheel is more dangerous than a puncture at a low speed than at the rear wheel, and a puncture at the rear wheel is more serious at a high speed.

The reason why the direction yaw after the puncture makes people have palpitations or talk about the direction deviation and discoloration, and the attention is focused on the front wheel, mainly because the driver can not correct the direction yaw at any speed, the objective reason is that the puncture wheel loses steering force, and the subjective reason is that the driver's reaction to the direction yaw lags for seconds, both at high speed and low speed.

Because the phenomenon of tire puncture occurs in various road conditions and various speeds, when we have a tire burst in the city or ordinary road section, although the speed is not fast, but because the direction yaw can not be corrected after the tire puncture and occupy the other party's lane or right lane (or rush to the sidewalk) to cause the serious consequences of a frontal collision or rear-end collision between two vehicles, even if there is no collision, it will be a cold sweat because of occupying the other party's lane or the right lane (or rushing to the sidewalk), if the collision (or collision with a pedestrian) the consequences can be imagined.

The direction yaw caused by the rear wheel puncture, the situation is much more complicated than the front wheel puncture, such as the right rear wheel puncture, the rolling resistance of the puncture wheel increases by about 30 times, resulting in the car being subjected to a clockwise side deviation moment, the side deviation moment makes the car yaw to the right side, and the lateral deviation moment simultaneously produces a transverse force directed to the inside of the puncture wheel, so that the rear of the car is subjected to the lateral force of sliding to the inside of the puncture.

At the same time, the lateral force produced by the rim rolling the tire after the puncture, the direction of the force points to the outside of the puncture wheel, so that the wheel produces a tendency to slip to the outside of the puncture, therefore, if the rear wheel bursts, the rear slip and tail flick of the car ultimately depends on the lateral force generated by the lateral force generated by the lateral deflection moment of rolling resistance and the rolling transverse force, who causes the wheel to slip first? This is related to factors such as road conditions and car driving conditions after a rear tire puncture, and we can see from the accident data that the rear tire tire slips outward and inward. After the slippage occurs, although the reaction is on the directional yaw, the driver cannot suppress the wheel slip by correcting the direction, to use a figurative analogy, it is like a person sliding under his feet and trying to adjust the direction of his body to avoid falling, no matter how properly your body is adjusted, you cannot avoid a body fall.

In the process of high-speed driving, the adhesion between the wheel and the road surface decreases by about 30%, and the ability to resist lateral slippage is greatly reduced.

Highway puncture accidents show that 70% of 80% of fatalities and injuries occur in the rear tyre!

When it comes to the danger of rear wheel puncture, it is inseparable from such a premise, that is, high-speed driving, if it is driving in urban sections, the speed is less than 80km h, the danger of rear wheel puncture is much lower than that of the front wheel, because the adhesion between the wheel and the road surface is enough to resist wheel slippage, which needs to be specially explained.

Of course, a puncture on the front wheel is dangerous! Because the front wheels are responsible for the steering function, if the front wheels are punctured, they will lose parallelism, and if they are high and low, the car will lose control and turn to the side of the puncture. If you encounter this situation, you must be calm, do not slam on the brakes, quickly grasp the direction, brake slowly, and let the car drive to the side of the road and stop.

Whether it is a front or rear tire puncture, there is a danger, relatively speaking, the front tire burst is more dangerous than the rear tire puncture, all drivers should concentrate on driving on the road, just in case.

Which is more dangerous with a puncture front or rear? This knowledge should be kept in mind, what should I do if I suddenly burst a tire when I was driving at a critical moment? The method taught by the old driver is really effective, keep in mind that the car has a puncture, the front wheel puncture is more dangerous than the rear wheel, and the rear swing is the rear wheel puncture, keep driving in a straight line, and brake lightly.

A flat tire in a car is very dangerous, especially on the highway, so which is more dangerous, a front tire puncture or a rear tire puncture? What is the safest way to get a puncture?

Which is more dangerous, front or rear? This life-saving knowledge must be mastered, take a look.

Rear tires, because if the rear tire bursts, the car will lose control, no matter what car will have rear-wheel drive.

A car tire puncture has a great impact on the life safety of every driver and passenger, and for a car, the risk of a puncture in the front wheel of a car is much greater than that of a puncture in the rear tire. The basis is that the front tire is connected to the steering wheel, when the front tire of the car is punctured, then the steering wheel will be driven, if the driver does not take the corresponding emergency measures, then the car front tire puncture will occur after the car rollover accident, serious will also cause the car to crash and die.

1. The risk of a puncture in the front tire of the car is higher than that of the rear tire.

Now for ordinary cars, the front engine is generally used, so the front tire of the car is the main stress tire that drives the car, so when the front wheel of the car bursts, then the car is easy to lose control. The rear tire has no relevant braking force, and the rear tire is also fixed, so when the rear tire bursts, it will not cause the car to roll over, unless it is caused by the speed of the car or because of the driver's improper operation. <>

2. Relevant basis.

In fact, the basis for this conclusion is very simple, the main basis is because the front wheel of the car is connected to the steering wheel, and after the current tire **, then the force on one side of the car is relatively large, which will cause the steering wheel to tilt towards the heaviest side of the force, and this will cause the car to roll over. However, the driver can correct the steering wheel for the front wheel of the car, that is, when the tire burst accident occurs, the driver holds the steering wheel tightly and brakes the car at the same time, so that the car will not roll over and cause a tragic traffic accident. <>

3. Summary. In general, the car facilitates everyone's traffic, but also brings a great safety hazard to everyone, and car tire puncture is a very dangerous thing, serious will also lead to car crash and death. Therefore, the owner must check the car tires in advance in the daily driving process, mainly check whether there are cracks on the surface of the tires, whether the tire pressure meets the requirements, as long as the owner does the relevant safety measures in advance, then it can greatly reduce the traffic accident rate.

I think a puncture on the rear wheel is more dangerous because a puncture on the rear wheel can cause a side slip, which makes it easy to roll over.

It's all quite dangerous, depending on whether your car is a front-wheel drive car or a rear-wheel drive car, if it is a rear-wheel drive car, the rear wheel of the mold cover is more dangerous. Dan Eggplant must eliminate potential safety hazards in time, and then must replace the wheel ridge tire in time, and the tire pressure should not be too sufficient in summer.

Generally speaking, a puncture at the rear wheel is dangerous; Because the rear wheel burst suspects that the car will lose control after taking the tire, the wild will suddenly oversteer, and the front tire will only deviate to the left or right.

Because the front wheel is the wheel that controls the direction, once the tire is punctured, it will not be possible to accurately adjust the direction in a short time, and the risk will be very high. Especially when driving at high speeds, once the tire bursts, the whole car will lose its center of gravity, and the driver will lose its balance pure lead silver, making it difficult to control the direction. ”

Rear wheel puncture. As the adhesion on one side of the tire disappears instantly, the car will immediately slide and flick its tail, just like a car sliding on ice and snow, and the direction is difficult to control. Especially for rear-wheel drive vehicles, when the rear wheels burst tires, the driving force of the wheels on both sides is inconsistent, giving the vehicle a yaw moment, increasing the speed and degree of vehicle skidding, and this kind of tail flick out of control situation is generally unsalvageable.

Precautions for punctures.

Insufficient or high tire pressure can lead to a puncture. In general, insufficient tire pressure and lack of air driving are the bane of punctures. If the tires continue to drive when they are out of air, the sidewall of the tires will be deformed, and a lot of heat will accumulate inside the tires after driving for a long time, which will eventually cause the car inside the tires to change and cause a puncture.

The best way to avoid dangerous situations such as high-speed punctures is to check your vehicle before you set off to prevent the danger in the cradle. When it comes to tire inspection, it is to check tire wear and tire pressure. When the tires are severely worn, they need to be replaced in time.

In terms of these two, the risk of a puncture at the front wheel is generally greater. Because the engine is in front, a puncture is prone to loss of braking power, leading to greater accidents.
