Why are run flat tires so expensive? What road conditions are suitable for choosing a run flat tire?

Hello friends, compared with ordinary tires, its performance has been improved and enhanced in terms of rubber material, sidewall thickness, etc., and the tire protection is better and more durable. In the case of insufficient tire pressure or air leakage, the vehicle can still drive normally at a certain speed or a certain distance. After ordinary tires are used, aging and cracking may occur in about a year and a half, while run-flat tires usually take more than three years to appear in a similar situation.

Hello, the run-flat tire is expensive in its function. Flat-proof tires are actually called "run-flat tires", which are not really "run-proof", but the probability of a run-out is very low, even if a run-out occurs, becauseThe sidewall is thicker and stiffer than ordinary tires, so in the case of no air, the sidewall can also support the weight of the car, ensuring that the tire will not be seriously deformed, greatly reducing the chance of a traffic accident due to a puncture.

Therefore, it will be relatively expensiveThe ** of a run-flat tire is about 1500 yuan, and it will be different depending on the brand and model. In addition, the cost of repairing and repairing the flat tire is high, and if the flat tire is punctured by nails, most of the cases cannot be repaired, and the tire can only be replaced with a new one.

As for what kind of road conditions are suitable for a run-flat tire, in general,If we often go on the highway, buying a run-flat tire can indeed greatly reduce the traffic accident rate. But if we usually only drive on urban roads, there is no need to replace the run-flat tire, after all, some urban road conditions are much worse than the highway, and the run-flat tire will be poor when driving on such a road surface, so it is good to use ordinary tires.

City roads are slower, and if you do experience a puncture, the owner can usually control the vehicle and don't have to worry too much. As long as we check the condition of the tires regularly, especially before hitting the highway, to see if the tires are damaged, cracked, aged, studed and other problems, the chance of a puncture can also be reduced. If you encounter tire problems while driving, you can choose the "tire maintenance" service in Ping An good car owners, tire repair, tire change, wheel alignment, wheel repair and other services can be done, and there are often maintenance coupons to give, for frequent travel car owners, in fact, it is very cost-effective.

When it comes to the difference between a run-flat tire and an ordinary tire, in fact, compared with ordinary tires, "run-flat tires" have a thicker and tougher sidewall, which can ensure the safety of the vehicle in the event of tire loss of pressure. In fact, "run-flat tire" is just a popular name, in fact, the scientific name of this tire is "run-flat tire", and only the kind of solid tire on armored vehicles used by the military and police can be called a real run-flat tire.

Although it is far from the real run-flat tire, the "black technology" technology on the tire can still allow the vehicle to continue to drive 80km at a speed of 80km h at 0 tire pressure, which greatly reduces the driving risk. In addition, if there is a difference between a run-flat tire and an ordinary tire, that is, the vehicle can no longer carry a spare tire, which not only saves the trunk space, but also achieves the purpose of weight reduction.

However, while "run-flat tires" have these advantages, they also have inherent disadvantages that are unavoidable, and this is one of the key points of what is the difference between run-flat tires and ordinary tires. Because the "run-flat tire" has a special reinforcement treatment on the tire wall, which forces the tire wall to harden, which also directly affects the tire's ability to filter road undulations and noise. Moreover, once the "run-flat tire" is punctured, it is very easy to cause secondary damage when repaired, so many OEMs have given the statement of "try to replace new tires as much as possible", which has led to the rise in the cost of using the car.

To be sure, the difference between a run-flat tire and a regular tire is actually obvious. If you often run long distances or at high speeds, the advantages of "run-flat tires" will definitely appear, but only on urban roads, the advantages of "run-flat tires" are relatively weakened. It can be seen that there are two sides to everything, and it depends on how we choose.

If mine is helpful to you, please remember!

Flat-proof tires are used in special models, and ordinary cars are not suitable for run-flat tires. Run-flat tires are relatively hard and thick, while ordinary tires are softer and more comfortable to use.

1. Solidity: The run-flat tire has one more layer of natural renewable rubber developed by nanotechnology than the sidewall surface of the ordinary tire, and the ordinary tire has been defeated in the solidity.

2. Abrasion resistance: when the tire has a puncture for various reasons, the run-flat tire can also travel normally for a distance without happening on the spot, at least we can drive to a safe area or go to the nearest repair shop for maintenance; However, ordinary tires cannot be driven normally after running out of air, and if a puncture occurs, it will be more dangerous.

3. Safety: If compared with its safety factor, the run-flat tire is definitely higher than the ordinary tire, and the run-flat tire has very high requirements for the shock absorption system of its vehicle, so it is necessary to find fault with the shock absorption system of the car when using the run-flat tire.

Flat-proof tires are different from ordinary tires in terms of **, material, and performance after a punctureBecause run-flat tires are expensive, ordinary tires are better than run-flat tires in terms of cost performance. The differences between them are:

1. **Different. Flat-proof tires are more expensive, much higher than ordinary tires. So run-flat tires often appear in luxury cars, and rarely in ordinary cars.

2. The material is different. Run-flat tires are composed of outer tires, common inner tubes, spare inner tubes, steel rims, gas generators (or air reservoirs), pressure sensors and control units, while ordinary tires are made of ordinary steel wire radial materials.

3. The use method after a puncture is different. Ordinary tires need to be stopped and replaced immediately after a puncture; Whereas, a run-flat tire can continue to drive for about 80 kilometers after a puncture, and then the tire is replaced.

I think run-flat tires are cost-effective.

What is the difference between a run-flat tire and a regular tire? Generally, when the tire loses tire pressure, the tire can break away from the hub like mud in the blink of an eye, and only rely on the hub to contact the ground. The biggest difference between a run-flat tire and a regular tire is that it has a very tough and supportive sidewall.

Such a design can help the tire in the event of a puncture or sudden deflat, to ensure that the tire and the hub can also be combined and give the vehicle a certain support, so as to ensure the safety of the vehicle.

Run-flat tires are run-flat tires, as the name suggests, run-flat tires can still be used normally after a flat air, so this kind of tire is also called a safety tire or a zero-pressure tire. Run-flat tires can still safely travel around 80 kilometers at normal speeds (e.g. 80 km/h) in the event of a complete blew of air.

What are the disadvantages of run-flat tires? Comfort is not good. Due to the reinforced design of the sidewall, the run-flat tire will be worse than the average tire in terms of tire comfort!

There's a reason I say that, like a Coke I just bought, it's filled with gas and liquid, which is equivalent to the reinforced sidewall of a run-flat tire, and in this state you pinch the bottle hard and it basically doesn't deform.

The main difference between a run-flat tire and an ordinary tire is the material and thickness, of course, a run-flat tire is more cost-effective.

The principle of run-flat tire is relatively simple, the scientific name is called: run-flat tire, the basic working and structural principle is, compared with ordinary tires, on the one hand, the sidewall of the run-flat tire itself is relatively thick, and at the same time, there are steel wires and related parts in the sidewall that support the tire in the case of safe gas loss. Such a structure guarantees a reduced chance of a puncture, even in the case of a complete air loss, the wheel hub will not touch the bottom, and the tire will not fall out of the rim, which is a great structural advantage in terms of safety.

Of course, in addition to safety performance, another advantage of the run-flat tire is that it is relatively hard, so the anti-wear ability of the run-flat tire is relatively strong, so the service life of the run-flat tire is longer than that of ordinary tires, at the same time, because the run-flat tire is not easy to blow out and can continue to drive a long distance at the same time, so these cars are generally not equipped with tires, so the space in the trunk may be relatively larger and deeper, which is also an advantage.

For explosion-proof tires, its advantage is that it is relatively hard, not easy to burst, and the disadvantage is also hard, because it is relatively hard, so when the vehicle is driving at low temperatures, the tire temperature of the tire rises very slowly, or the tire temperature has been very low, resulting in the result that the tire bounce is more obvious, affecting the comfort, but also affecting the grip of the vehicle.

The main difference between the two types of tires is the material and thickness, if you want to say that the cost performance is high, I think ordinary tires are high, and in most cases we don't need to install run-flat tires for our cars.

Flat-proof tires can not prevent punctures, pressing sharp stones, external forces, etc., will also puncture tires, in fact, the probability of puncture is not smaller than ordinary tires. But because its tire sidewall is very thick and hard, even if the air pressure is zero after a puncture, it will not be flattened, and the sidewall still has good support, so the height of the car will not change, and naturally it will not suddenly deviate to one side, so it will indeed be safer.

With zero air pressure, this tire can also support the vehicle at a speed of 80 km/h for more than 50 km/h. Therefore, vehicles equipped with run-flat tires do not have spare tires and cannot be used at all, which can not only increase the trunk space, but also reduce the weight of the vehicle. The above are the advantages of a run-flat tire, and the biggest feature is to be able to continue driving after a puncture.

Since most cars do not use run-flat tires, it must have shortcomings, that is, the cost is too high and the comfort is poor, and it is precisely because of its shortcomings that it cannot be widely used. A run-flat tire is about 1500 cheap, and ordinary tires may only cost seven or eight hundred, which is twice as expensive. In addition, the run-flat tire cannot be equipped with ordinary wheels, and special wheels are also required, which are also higher than ordinary ones.

After using the run-flat tire, it is not only the highest height of the wheel, because the tire becomes stiffer, the cushioning effect becomes worse, so the impact of the road surface is easily transmitted to the suspension and body, and the vehicle comfort becomes poor. For the comfort of the vehicle, as well as the suspension and the life of each component, many parts need to be strengthened and high-grade materials are used, and the chassis also needs to be specially tuned, and the overall cost is much higher.

The main difference between run-flat tires and ordinary tires is that run-flat tires are thicker and safer, but I personally think that ordinary tires are more cost-effective.

Run-flat tires are also known as run-flat tires. This kind of tire can travel a normal distance after a leak, and can generally continue to drive about 80 kilometers at a speed of 80 kilometers.

If conventional tires are used, the vehicle is likely to have a violent collision, rollover and other traffic accidents after a puncture. And even if the tire is flat even if this kind of airtight tire occurs, the driver and passengers in the car may only feel the "body sinking" and the direction is slightly shaking, and the safety is indeed much higher than that of ordinary tires.

However, because the sidewall of run-flat tires is much thicker than that of ordinary tires, the bounce of vehicles with slight potholes on the ground will be very intense, and the comfort of drivers and passengers will be greatly reduced. Not all vehicles can be fitted with this type of tire, depending on the design of the tire and wheel.

Run-flat tires will be more fragile when driving on potholes, due to the design and material of airtight tires, if you encounter potholes, the side of the tires will bulge as long as the side of the tires is slightly scratched and collided.

The difference between run-flat tires and ordinary tires is: 1. Run-flat tires have higher safety and can effectively reduce the risk of punctures. 2. Using such tires, in the event of an air leak or puncture, you can travel 80 kilometers at a certain speed, which is enough for you to find a nearby maintenance point for maintenance.

3. The weight of the run-flat tire is heavier than that of the ordinary one, and the hardness is higher, so the driving comfort is reduced. 4. The first level of run-flat tires is higher. On the whole, it is more cost-effective to have a flat-proof tire.

At present, the well-known major tire manufacturers have mastered the corresponding airtight technology. In addition, they will put a special air-deficit logo on products such as run-flat tires, such as Michelin's RSC, Chaoyang's ZRT, Continental's SSR, etc.

If you want to replace the run-flat tire, in addition to finding such a mark when selecting, you also need to distinguish between the two different "explosion-proof" technologies mentioned above, rigid support and self-sealing, the current mainstream is the support run-flat tire.

It should also be noted that there are now 4S shops that sell run-flat tires that are only replaced and not replaced, and when you go to the roadside shop, because the tire wall is too hard to pick, the roadside maintenance master is generally not very "cold"; At the same time, there is a possibility of ruining the tire. This situation causes a run-flat tire, and it is generally difficult to repair the tire when the tire is broken. This also increases the cost of using a run-flat tire.

1. If you usually drive more so-so, big grinning, and often run at high speed, then you can choose a run-flat tire appropriately. But be sure to pay attention to your wheels, whether they are suitable for installing run-flat tires, and cannot be replaced casually. If you like to play with cars, like plastic wheels, enlarged wheels, then it is recommended not to easily choose run-flat tires, try to choose ordinary tires.

2. There is an RSC logo on the run-flat tire, which means that it can be controlled stably when running, so its scientific name is run-flat tire, which means that after your tire is flat, you can continue to run, not a tire that will not burst.

3. Compared with ordinary tires, the sidewall of the tire is made of a very thick, very hard rubber, particularly hard, and can not be pressed by hand.

4. Run-flat tires, also known as run-flat tires, as the name suggests, can continue to drive for a period of time at about 60km per hour, and run to the place where the tires are repaired to repair or change the tires! It's not explosion-proof and puncture-proof. The main feature is that the tire wall is relatively thick, which can support a section of body weight without gas!

The disadvantage is that it is expensive, the tire noise is large, and there is no special need to buy a run-flat tire, just an ordinary tire.
