How to distinguish a run flat tire from an ordinary wheel?

With the continuous improvement of everyone's living standards, the car is a vital means of travel for everyone, often in use, there will be all kinds of questions, today to introduce to you is the difference between run-flat tires and ordinary tires? This question, if you are interested, let's popularize science together.

The differences between run-flat tires and ordinary tires are as follows: 1. In terms of appearance, run-flat tires have special logos. Special markings are usually placed behind the specifications on the sidewall of the tire.

This logo varies depending on the tire brand. For example, Pirelli's explosion-proof mark is R-F; Continental's explosion-proof symbol is SSR; Bridgestone's explosion-proof mark is RFT; Michelin's explosion-proof logo is ZP; Dunlop's explosion-proof mark is ROF or DSST.

That is to say, if there is a special mark, it is a run-flat tire; If there is no special mark, it is an ordinary tire.

2. Structure: the sidewall of ordinary tires is relatively thin; Flat tires have thicker sidewalls. Due to the different structures, run-flat tires are stronger, more wear-resistant, and safer than ordinary tires.

3. Performance: In addition to the function of ordinary tires, the run-flat tire can also make the vehicle travel a certain distance under the condition of zero air pressure of the tire. It is usually up to 80 kilometers per hour.

4. Flat-proof tires are heavier than ordinary tires. If the car is fitted with four run-flat tires, it is equivalent to the weight of one more person seated.

5. The comfort of run-flat tires is not as good as that of ordinary tires.

The difference between a run-flat tire and a regular tire.

The difference between run-flat tires and ordinary tires is material, safety, and wear resistance.

One of the biggest differences is safety, run-flat tires are not to prevent punctures, but in the case of air leakage or sudden loss of pressure, the vehicle can still travel 80-250 kilometers at a speed of 80 kilometers per hour (please refer to the vehicle manual), and ordinary tires if they continue to drive after a puncture or lack of air, the tire wall temperature will rise and cause irreversible damage to the tread, and in serious cases, it will also damage the rim.

The easiest way to distinguish between run-flat tires and ordinary tires is to see whether there is an explosion-proof logo on the sidewall, there is an explosion-proof tire with an explosion-proof tire, and there is no ordinary tire, and the general explosion-proof logo is RSC, but the brand is different, and the explosion-proof logo of some run-flat tires is different.

Bridgestone's explosion-proof logo is RFT, Pirelli's explosion-proof logo is R-F, Continental's explosion-proof logo is SSR, Dunlop is ROF, Michelin's explosion-proof logo is ZP, and sometimes Michelin's explosion-proof logo is RSC. The explosion-proof logo is not a patterned model, but a combination with a patterned model, such as: Michelin Primacy HP ZP.

In addition to distinguishing between run-flat tires and ordinary tires by explosion-proof signs, you can also identify them by feeling and pressing the sidewall by hand, which is thicker and stronger than ordinary tires. However, this differentiation method is more effective for comfortable tires with soft sidewalls, and for wear-resistant tires, the sidewall is also very hard, and the perception is not obvious, so it is difficult to distinguish. It is still easiest to distinguish by explosion-proof marking.

In addition to safety, run-flat tires and ordinary tires are also different in **, run-flat tires are higher than ordinary tires, and the maintenance cost in the later stage is also higher than ordinary tires; The materials used in the two are also different, the run-flat tire is composed of an outer tire, a common inner tube, a spare inner tube, a steel rim, an inflator (or air reservoir), a pressure sensor and a control unit, while ordinary tires use ordinary steel wire radial material tires.

Hello, the sidewall of run-flat tires is much thicker than the normal one. In addition, run-flat tires will be marked with SSR, RSC, RFT, etc.

Run-flat tires are much stiffer than regular tires.

Look for these three letters on the tire to teach you to easily distinguish what a run-flat tire is!

Hello, run-flat tires, that is, the lifting test is relatively thick.

1. In terms of structure, the sidewall of the run-flat tire is thicker than that of ordinary tires, which is used to support the weight of the vehicle after the tire is deflated.

2. In terms of comfort, the comfort of run-flat tires is worse than that of ordinary tires, because the shock absorption effect will be relatively poor due to the hard sidewall.

3. In terms of noise, the tire noise of run-flat tires is greater than that of ordinary tires.

4. In terms of puncture tires, run-flat tires are more expensive than ordinary tires, generally several times that of ordinary tires, and the cost of replacing tires with four wheels is very expensive. At the same time, the run-flat tire is also equipped with a tire pressure detection system to detect whether there is a puncture, and these tire pressure sensors are also very expensive, because the run-flat tire is more expensive than ordinary tires.

5. In terms of service life, because the tire wall of the explosion-proof tire is thick and difficult to pierce, the service life is longer than that of ordinary tires.

Generally speaking, the difference between a run-flat tire and an ordinary tire is that a run-flat tire can continue to drive on the road in its original state even if it has a puncture, but in contrast, an ordinary tire will lose pressure immediately after a puncture, and the vehicle will lose its balance and cannot continue to support the drive. 

The difference between run-flat tires and ordinary tires is also in the sidewall material of the two tires, the run-flat tire is wear-resistant, thickened and strengthened design, it itself comes with a reinforcement configuration, but it is not that it will not burst the tire, but after the puncture, the vehicle is still in the driver's control, and can drive normally at a speed of 80 kilometers per hour. After a puncture, the run-flat tire is safer, because it is supported by a thickened sidewall, which will not directly leak and affect the driving.

Flat-proof tires are only stiffened compared to the sidewall of ordinary tires, and the overall comfort is much worse. Now the run-flat tire is not the latest technology, and the comprehensive performance of the Rubber Wolf brand spraying self-sealing safety leak-proof tire on the market is very good, which greatly improves the comfort during driving while ensuring driving safety.

The distinction between run-flat tires and ordinary tires is as follows:

1. The differences between RSC tires and traditional wheel training empty shed tires include explosion-proof characteristics, reinforced sidewalls, additional valve strips and synthetic rubber loss rubber materials with high heat resistance.

2. RSC In the case of deflated tires, the vehicle can still travel 250 kilometers at a speed of 80 kilometers per hour; A normal tire burst makes it impossible to drive immediately.

3. The RSC run-flat tire is equipped with a device called a fixed ring, which can support the tire from the inside, so that the tire will not be crushed, and at the same time, it can also prevent the tire from falling off the tire gasket, and the owner will not feel the puncture; Accidents can occur after a normal tire puncture and there is a loud sound.

1.Robustness: Flat-proof tires have an extra layer of natural renewable rubber developed by nanotechnology than the sidewall surface of ordinary tires, and ordinary tires have lost the upper hand in terms of robustness.

2.Abrasion resistance: When the tire has a puncture for various reasons, at this time, the run-flat tire can also travel normally for a distance without happening on the spot**, at least we can drive to a safe place 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 the safety factor is higher than that of the flat tire, the run-flat tire is definitely higher than the ordinary fetal fluid, 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.
