Does the sidewall of a car tire affect the operation of the car?

In the process of driving, once the tires **, the direction of the car will quickly deviate, and accidents may also occur.

The so-called "wounded" tires generally refer to the leakage holes on the sidewall of the tires, and the road that the owner walks on in daily driving is more complicated, so the phenomenon of puncture tires is inevitable. Stationmaster Xu told reporters that tire puncture injuries are generally leaks on the front that can be repaired, and they can be used normally after repairing, but if the tire sidewall or the leakage hole in the angle between the tire sidewall and the tire surface cannot be repaired, even if it is repaired, do not use it again.

Tires are ring-shaped elastic rubber products that are grounded and rolled on various vehicles or machinery. It is usually installed on metal rims, which can support the body body, cushion external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they bear various deformations, loads, forces, and high and low temperatures when driving, so they must have high load-bearing performance, traction performance, and cushioning performance.

At the same time, high abrasion resistance and flexural resistance, as well as low rolling resistance and heat generation are required. Half of the world's rubber consumption is used in tire production, which shows the ability of tires to consume rubber.

Tires are one of the most important components of a car, and its main functions are:

1. Support the full weight of the vehicle, bear the load of the car, and transmit the force and torque in other directions

2. Transmit the torque of traction and braking to ensure good adhesion between the wheels and the road surface, so as to improve the dynamics, braking and passability of the carTogether with the car suspension, it can cushion the impact of the car while driving and attenuate the resulting vibrations

3. Prevent auto parts from severe vibration and early damage, adapt to the high-speed performance of the vehicle and reduce the noise during driving, and ensure the safety, handling stability, comfort and energy-saving economy of driving.

Of course, car tires are generally semi-steel tires, and the sidewall is nylon wrapping, if the nylon is broken, the strength is not enough. It was swollen, and there was a danger of a puncture at high speed!

Of course, once there is a slight impact or extrusion, it will crack, although it will not be like a steel wire tire puncture, but it will quickly unwind, especially when the vehicle is driving at high speed, it will have a big impact on the safety of the vehicle, mainly because the direction is unstable, and the high speed refers to more than 50 kilometers. Let's change it as soon as possible.

The tires we commonly use are wrapped in rubber with a mesh of woven nylon and other materials to limit the amount of carcass expansion, and some nets also have the effect of maintaining the carcass shape. If the wire of these nets is broken in some places, and the broken wire area is large to a certain extent, this part of the carcass rubber will be "blown" by internal pressure like a balloon, and a bag will be formed. If this happens, it can't be repaired and must be replaced.

No, it's safer to put it on the rear wheel. Having said that, it is better to replace it if possible.

In short, as long as the tire is bulging, there must be a break in the ply layer in that place. How can a good ply layer break? It is generally caused by external forces, such as being squeezed, impacted, etc.

If you pull over and get too close, the tire will squeeze on the road tooth, or when you go directly to the road tooth, it will squeeze into the tire sidewall, and the deformation will be too large after squeezing, and the cord will be broken. There are also speed bumps, pits and other things that do not slow down, and the tires suddenly hit it, which will also lead to breakage, which is caused by sudden excessive deformation. It's like when we take a thread and pull it slowly, it's hard to break it, and it hurts to strangle your hand, but if you push hard, it's easy to break it.

After the tire is swollen, it cannot be repaired, because the cord is broken, and the cord cannot be connected or replaced by repairing, and the cord is in the middle of the rubber and cannot be operated. As long as it is bulging, you must immediately replace it with a new tire, even if it is a new car that you have just bought. Therefore, before driving long distances, you must do a tire inspection, in addition to checking the tire pressure, the tire bulge is also a major item to check, because the bulge to check the tire pressure can not be checked.

Once it is bulging, if you continue to use it, sooner or later it will have a puncture, and it will get bigger and bigger, and eventually lead to a burst.

People often ask if the sidewall of the tire is injured, can it still be used? If there is no bulge, just be cut, look at the depth of the cut, if it leaks out of the cord layer, it can not be used, it is recommended to replace it, if there is no leakage of the cord layer, you can continue to use. If you open the wound and look closely, the cord layer is easy to see, and it is some white threads.

Many accidents are caused by sudden punctures in cars, in fact, cars have signs before a puncture, today we will tell you about the bulge on the tire.

Of course, it affects the safety performance of the car.

Sooner or later, there will be a puncture, and it will bulge more and more, eventually leading to a burst.

The tires of the car can burst at any time.

It will affect the normal performance of the car.

Sooner or later, the car will have a flat tire and must be replaced with new tires immediately.

If you use it all the time, this bag will break sooner or later.

If you keep using it, you will eventually get a puncture.

Chengdu tire wholesale specifically pointed out that the front of the tire is flooded with "bulge", which not only affects the driving, but also has the risk of puncture, which is a major hidden danger for the vehicle. Therefore, if there is a "bulging" situation, you must immediately go to a regular tire store for professional testing and replacement.

Too much air pressure or too little gear belt can have a negative impact on the tire. If the air pressure is too large, the tire will become harder, and the contact area between the tread and the ground will be reduced, which will affect the handling and ride comfort, and the tire will be easy to wear; If the air pressure is too low, the tire base will become softer, the fuel consumption of the vehicle will rise, and the tire will easily break due to large shear stress between the obstacle and the rim when it is impacted.

Some consumers asked: Will the "bulging" situation on the side of their car tires affect the driving? There is no danger of a puncture.

To this end, relevant experts remind consumers: the side of the tire appears "bulging", not only affects the driving, but also has the risk of puncture, must be replaced as soon as possible. He said that in addition to the possible quality problems of the tires themselves, improper use methods and poor driving habits are important reasons for this situation.

Since the vast majority of cars currently use radial tires, the tire sidewall is its weakest part. Because the entire radial tire, only the sidewall has no wires, so great care must be taken in use. When driving at high speed in bad road conditions, the tire may hit a deep pit or other foreign objects, resulting in serious extrusion deformation of the tire between the impact object and the rim flange, resulting in the broken yarn of the tire wall cord, and then the air inside the tire will rise from the broken yarn to form a bulge.

In addition, frequent scratching of the tires on the road and when parking may also cause damage to the tire wall and "bulge". Experts say that tires that are "bulging" can no longer be used because they may burst at any time, which is a major accident hazard for vehicles. In recent years, the development trend of foreign car tires is to increasingly use tires with large width, large inner diameter and low aspect ratio.

The so-called "flat ratio" refers to the ratio of the maximum width measured from the section of the tire to the height of the rim to the tread, expressed as a percentage, i.e., the height as a percentage of the width. After the vehicle is equipped with tires with large width, large inner diameter and low aspect ratio, in addition to strong handling, the appearance and visual effect also give people a very powerful feeling. However, experts caution that, generally speaking, the tires that the vehicle is equipped with when it leaves the factory are the best specifications selected by the manufacturer after repeated tests.

If there is a car owner who wants to change the tire size, it must be done under the guidance of a professional, and it cannot be done arbitrarily. Because there are many problems involved, the slightest negligence can cause harm to driving safety. In addition, the low flat tire will appear more "delicate", and should be more careful and cared for during use.

The tire sidewall needs to be replaced if there is a bulge and scratches, because the bulge means that there is one or more fractures of the steel wire inside the tire, resulting in the rubber can not withstand the pressure inside the tire, so there will be a bulge phenomenon, and the tire wall scratch is also very dangerous, because the tire sidewall is the weakest part of the tire, and the scratch will destroy the strength of the tire sidewall, resulting in a part of the tire sidewall The rubber becomes thinner, and the rubber can not withstand the pressure inside the tire after the rubber is thin, and the tire may burst if it cannot withstand the pressure inside the tire. Generally, bulging and scratches are caused by external force damage to the tire. Therefore, it is recommended that car owners do not pull too far aside as soon as possible when parking to prevent the tire sidewall from rubbing against the road teeth and causing the tire to bulge.

If there is a bulge and scratch failure, it is necessary to replace the tire to prevent the vehicle from bursting in continued use.

The appearance of "bulge" on the side of the tire not only affects the driving, but also has the risk of puncture, which is a major accident hazard for the vehicle. Therefore, if there is a bulging situation, it is absolutely impossible to use bulging tires again. Be sure to go to a regular tire shop for professional inspection and replacement immediately.

Packing tires will definitely affect the driving force, and even affect life safety, so the most suitable thing is to replace the tires as soon as possible, and then repair the vehicle.

Absolutely, bulging is a manifestation of tire damage after all, regardless of high speed or low speed, there is a possibility of danger, and this possible timing is not artificial, it is a risk factor that can occur at any time.

I can't use it. Bulging tires are a major hidden danger for the safe driving of automobiles, which can easily lead to punctures. Therefore, once you find that the tire is bulging, do not consider any other way of repairing, and need to replace the tire with a new one as soon as possible.

There are two main types of tire bulges: cord break bulge and delamination bulge, and there are three main types of delamination bulges, crown hollow, shoulder hollow, and sub-mouth hollow. Tire bulging is the most common phenomenon in tire damage, and there are many reasons for bulging, generally speaking, most of the occurrence of tire bulging phenomenon is due to the unexpected and intense impact in use. And if the tires bulge a lot, it is largely due to quality problems.

According to the relevant regulations of the industry, the normal service life of general tires is 3-5 years from the date of manufacture. If, within this period, it is not due to a special reason such as a collision, then there may be a problem with the quality of the tire. Too much or too little air pressure can have a negative impact on the tires in the city.

If the air pressure is too large, the tire will become harder, and the contact area between the tread and the ground will be reduced, which will affect the handling and ride comfort, and the tire will be easy to wear; If the air pressure is too low, the tire will become softer, the fuel consumption of the vehicle will rise, and the tire will easily break due to large shear stress between the obstacle and the rim when it is impacted. Measures to avoid bulging: First, when installing tires, please go to a professional tire shop and use professional tire installation equipment and professional installation procedures to operate.

Second, try to avoid driving in bad road conditions for long periods of time, and if you can't avoid it, please pay attention to the slower the speed, the better. Third, develop superior tire maintenance habits, check tires frequently, carefully check whether the tire surface is cracked, scratched, bulging, excessive tread wear and other potential dangers, and adjust at any time to prevent puncture. Fourth, in addition to inspecting tires on schedule, car owners also need to check and maintain normal tire pressure, pay attention to the tire warranty period, and ensure their use"Health"tires to drive the vehicle.

It can't be used.

It must be replaced.

Because the sidewall does not have a steel wire layer, when the tire drives through potholes, obstacles and curbs at high speed, it may be hit by sharp and hard objects instantaneously, which exceeds the bearing capacity of the sidewall, resulting in slack or fracture of the sidewall cord and cause bulging.

Bulging tires are very dangerous, they can burst at any time, and they cannot be repaired, so they should be replaced as soon as possible.

Remind the majority of car owners and friends to slow down in time to avoid or pass slowly when they find pits or obstacles in front of them while driving, so as not to cause unnecessary economic losses.

When encountering a relatively deep and not very wide pit, it is pressed over, and the speed is quite fast, and it is the easiest to bulge!

1. After the tire is inflated, it is found that there is a bulge, which is a quality problem, generally because the tire parts material joints are poor, and the dissection of this part may find foreign bodies or uneven stretching of the cord resulting in sparse cord.

Second, after the tire is used, it is found that there is a bulge along the radial direction, and it can be seen if it is not inflated when it is serious. It is mainly due to the collision of obstacles or punctures on the tire surface during the driving of the vehicle, which causes part of the cord to break, and the corresponding side causes bulging; Or the cord itself is sparse and the material is not properly jointed.
