What should I do if the tires of the car are broken?

First of all, in the case of a spare tire in the car. If you feel that something is too wrong, then you can stop the car and take a look, whether there is a problem with the tire, then if you find that the tire is pierced with nails, you can first try to see if the tire is running out, for example, you can pour some water on the tire or spit on the tire, to see if there is bubbling in the punctured place, according to this to judge whether there is a leak, then at this time you can replace the spare tire first, and then take the punctured tire to the auto repair shop, Don't think that the tires are not blowing and you can continue to run, because during the exercise, the nails may be pierced deeper, which will really puncture the tires. Of course, there are some people because the tire screws are tightened very tightly when changing tires in winter, and they find that they can't be screwed in summer, so they can't change the spare tire at all, so we can refuel the car according to the degree of tire running, and then find a nearby auto repair shop to repair the tire.

If you don't have a spare tire, first of all, don't think about pumping when the tire runs fast, and then drive for a while, in this case, either you go to a familiar auto repair shop to find an auto mechanic to help you, or call ** to the insurance company to apply for towing services. Some car owners have also learned how to repair tires before buying a car, so I can tell you about a more convenient way to repair tires, which is the most common way to patch rubber strips, in fact, it is to shoot guns to repair, this way is relatively simple, no need to remove the tires. You can go to a special auto repair shop to buy a special rubber strip, and then you can find the hole that is pierced, enlarge the hole a little bit, and then plug the hole with a glued strip, this method is very simple, and it can be done in a few minutes.

However, it is not possible to avoid the quality of the rubber strip bought in the auto repair shop, which may cause the rubber strip to fall off or the tire is still running slowly in the process of driving, and the use time is not long, but it is still okay to do a first aid, and then go to the auto repair shop to make up for it.

If only one tire is flat, you can choose to replace the spare tire and go to the repair shop to repair it. If there is sealant in the car, you can inject sealant into the tires, and the sealant is stored in a compressed air tank, and when used, it is injected into the tires through the valves, and the liquid can be injected into the tires at the same time. If you don't have a spare tire, the best thing to do is to call roadside assistance for a tow truck or call for a mobile tire repair service.

If the tire is broken, it is recommended that you can't drive, you need to find a safe place to wait for rescue, and wait until the maintenance master arrives to disassemble the tire and repair the tire.

<> "Tires on vehicles are one of the most susceptible to wear and tear, due to their direct contact with the ground to produce friction, not only wear out quickly, but also easy to be damaged by some hard foreign objects, resulting in damage. So what should I do if the car tire is broken?

When the car tires are damaged, you need to choose a solution according to the degree of damage to the tires, the details are as follows:

If the tire is only slightly damaged, such as the sidewall or tread is slightly damaged, the rubber on the surface is only rubbed off a little, which will not affect normal driving and does not need to be replaced; If it is punctured by sharp objects such as iron nails and steel wires, it is only a small luming mark hole less than 6mm, which can be repaired and continued to be used.

If the tire is seriously damaged, you must stop driving, check it in time, replace the tire or wait for rescue; For example, the following situations occur: the tire is cut by a sharp object, and the length of the damage exceeds 6mm; The tread pattern falls off, resulting in no friction on the tire; Tires are corroded by chemicals; The carcass structure inside the tire is damaged, resulting in deformation of the tire; The cord on the sidewall of the tire is broken, resulting in unstable air pressure in the tire, and the tear is opened, and the tire wall is swollen.

Causes of total tire breakage:

1.The tire pressure is too high.

When the tire is used under high air pressure, the contact area between the tire and the road surface becomes smaller, and the pressure increases, which accelerates the wear of the middle of the tread; When the tire pressure is too high, the stress of the carcass increases, so that the cord layer is subjected to excessive tensile strength decreases, the elasticity is reduced, it is easy to be punctured by sharp objects, and the carcass may also burst when it is subjected to a large impact. In addition, high tire pressure will also reduce the grip of the tire, resulting in longer braking distance; Affects comfort and exacerbates wear and tear on chassis components.

2.Tire pressure is too low.

Tire pressure that is too low can cause more serious damage to the tire. This is mainly due to the increase of sidewall deformation, so that the cord layer in the carcass produces excessive alternating stress, periodic compression deformation will accelerate the fatigue damage of the cord, at first the rubber line is detached, and then it will be quickly broken, so that the tire is scrapped prematurely; When the tire rolls at low pressure, it will aggravate the heat generation temperature of the tire, and when the tire temperature is too high, it will also lead to local delamination of the carcass A, friction between the cords, and the temperature at the place of delamination.

Higher, it is also more likely to cause sidewall bursting; When the tire pressure is low, the middle load of the tread becomes smaller, and the edge load increases, causing the shoulder pattern to be severely worn. Low tire pressure not only increases tire wear, but also increases rolling resistance and increases fuel consumption.

3.Overloaded tires.

The characteristics of tire damage during overloading are similar to those when driving at low air pressure, but the wear and damage to tires from overloading is more severe. Due to the large deformation of the tire, the stress on the sidewall is too large, so that the fatigue of the tire material and its strength are reduced faster, and the cord layer is most likely to break or burst on the sidewall; When an overloaded tire rolls into a stone, a crown burst often occurs. Practice has shown that with a 20% overload, tire life will be reduced by 30% and rolling resistance will be increased by 40%.

Overloading inevitably causes early damage or scrapping of wheeled tires.

4.Failure of the chassis.

In driving, due to the poor technical condition of some mechanisms of the automobile chassis, it is also an important cause of abnormal wear or damage to tires. Among them, the biggest damage to the tire is the inaccurate alignment of the front wheel, especially the front wheel is too large or too small will make the front wheel appear rolling with slippery phenomenon, resulting in serious wear of the tread on one side, and the pattern on the other side, even if the deviation from the standard is not much, it will also lead to the eccentric wear of the tread. Faulty front wheel alignment not only causes damage to the tires, but also directly affects steering performance.

In addition, the deformation of the frame or suspension, the displacement of the rear axle, the loose ball joint or knuckle of the steering tie rod, the excessive clearance of the wheel bearings, and the lag or locking of the brakes will cause abnormal wear and tear of the tires. Therefore, regular maintenance of the vehicle and front wheel alignment, especially the steering and braking systems, to keep it in good technical condition, will play a very important role in reducing tire wear and prolonging the service life.

In addition to the above-mentioned reasons for vehicle conditions, another reason for shortening the use of tires is directly related to the driver, such as: sharp start, sharp acceleration, sharp braking, sharp turning, speeding, playing in the same direction, not paying attention to the choice of road surface, rolling obstacles, inspection and repair are not timely, etc.

1. In the case of a spare tire in the car, stop the car and take a look at whether there is a problem with the tire, so if you find that the tire is pierced with nails, you can first try to see if the tire has run gas, for example, we can pour some water on the tire or spit on the tire Li Song, to see if there is bubbling in the place where it is pierced, according to this to judge whether there is air leakage, then you can replace the spare tire at this time.

2. Then take the punctured tire to the auto repair shop, don't think that the tire is not bubbling and you can continue to run, because in the process of exercise, the nail may be pierced deeper, so that the tire will really be punctured.

3. In the case of no spare tire, either you go to a familiar auto repair shop to find an auto mechanic to help you, or you can call ** to apply for towing services from the insurance company.

<> "Some unexpected situations may occur during the use of the car, among which the car tire burst is more common. So how to repair a car tire burst?

If the car tire bursts, it cannot be repaired, because the internal structure of the tires has been seriously damaged after the puncture, even if it is repaired, the probability of the wound reappearing in the later stage will increase, which is a great threat to our own safety, and it is recommended to replace the new tire in time.

After the tire of the car bursts, the owner should hold the steering wheel with both hands, try to make the car drive in a straight line in the original direction, quickly hook into the low-speed gear, use the engine to brake the vehicle, lightly step on the brakes, slow down to park the car on the side of the road, press the danger warning lights and place warning signs in time to avoid collisions with rear vehicles.

In addition, the owner should also pay attention to the daily use of the car, regularly check the tire pressure and other conditions, many times may be due to weather changes, or the road surface is more bumpy, the tire is out of gas, so the owner had better check the tire once a month or two months.

Replace the tires and take them away. Old car tires can be sold, generally ** in 5-40 yuan, depending on the condition of the tire; In order to avoid being used by some unscrupulous merchants, you can also choose to take it away, usually these old tires will have dealers who specialize in second-hand tires, but it is not excluded that some unscrupulous tire manufacturers, in order to reduce the production cost of tires, directly take the old tires and spray the tire oil and repair the obvious scars, and label it to take it out as a new tire**.

Precautions for changing tiresThe original car tires usually take a little longer, and the specific tire use time depends on the road conditions, vehicle conditions, driving habits and other factors. When the depth of wear of the tire pattern reaches a certain level, the tire needs to be replaced, and the triangle symbol corresponding to the groove on the side of the car tire is the bottom wear mark of the tire pattern, and the national calibration is or, when the tread pattern is worn to the PWI, the tire needs to be replaced.

Normally, the replacement of tires can only be replaced with the original specifications, but the three parameters of the tire specifications: such as the width of the nominal section, the flattening rate, and the rim diameter can be replaced by the tire upgrade. Specific tire upgrades involve more and require professional personnel to achieve specification replacement through formula calculation.

Whether it is replaced or repaired, it depends on the degree of damage to the tire, and whether there is a need to repair it.
