The difference between run flat tires and regular tires

1. Differences in appearance.

Run-flat tires have special markings. 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.

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

2. Structural differences.

Ordinary tires have relatively thin sidewalls; Flat tires have thicker sidewalls. Due to the different structures, run-flat tires are stronger, more wear-resistant, and safer than ordinary tires.

3. Differences in performance.

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

4. The difference in weight.

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

5. Differences in comfort.

The comfort of a run-flat tire is not as good as that of a regular tire.

What is the difference between run-flat tires and ordinary tires, it can really be explosion-proof for 1 minute for you.

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 difference in appearance Flat tires have special markings. Special markings are usually placed behind the specifications on the sidewall of the tire. Structural differences: Ordinary tires have relatively thin sidewalls; Flat tires have thicker sidewalls.

The difference between run-flat tires and ordinary tires is in terms of structure, comfort, noise, quality, and life.

The difference between run-flat tires and ordinary tires is material, land leakage, safety, wear resistance, the biggest difference 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).

If the ordinary tire continues to drive after a puncture or lack of air, the tire wall temperature will rise and cause irreversible damage to the tread, and in severe cases, it will also damage the rim.

Tire features:

The easiest way to distinguish a run-flat tire from an ordinary tire is to see if there is an explosion-proof logo on the sidewall, there is a explosion-proof tire with a cautionary explosion-proof logo, 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. 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, a pressure sensor and a control unit, while the ordinary tire is composed of ordinary steel wire radial material.

In addition to returning to the hall, you can distinguish between run-flat tires and ordinary tires through explosion-proof signs, and you can also identify them by feeling, pressing the sidewall by hand, and the sidewall of run-flat tires is thicker and stronger than ordinary tires. 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.

Differences in appearance Flat tire hoods have special markings. The special marking is generally behind the specifications on the sidewall of the tyre. Structural differences: Ordinary tires have relatively thin sidewalls; The side wall of the tire beam of the run-flat tire is thicker.

The differences between run-flat tires and ordinary tires are: different materials, different wear resistance, different structures, different comforts, different noises and different safety.

1. Different materials: Explosion-proof tires are mainly made of natural rubber with a thick layer of explosion-proof and nano-renewable technology on the side wall of their tires.

2. Different wear resistance: when the tire has a puncture, the run-flat tire can travel normally for a certain distance, and the ordinary tire cannot drive normally after running out of air.

3. Different structure: the sidewall of the explosion-proof tire is thicker than that of ordinary tires, which is used to support the weight of the vehicle after the tire is deflated.

4. Different 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 stiff sidewall.

5. The noise is different: the tire noise of the run-flat tire is greater than that of ordinary tires.

6. Different safety: Comparing the safety factor of these two types of tires, the run-flat tire is definitely higher than that of ordinary tires. Flat-proof tires are more stringent when using run-flat tires because the shock absorption system of the car is very high.

Analysis of the advantages and disadvantages of run-flat tires

Pros:

Compared with ordinary tires, the tread design of run-flat tires is thicker and stronger, and the sidewall has a strong ability to resist deformation.

In the case of air leakage or sudden loss of pressure, the vehicle can still travel 250 kilometers at a speed of 80 kilometers per hour (please refer to the vehicle manual), the solid sidewall can ensure that the tires and wheels will not be deformed, and the center of gravity of the car will not be offset, which can ensure the safety of driving.

Cons:

Because of the sidewall design of the run-flat tire, the tire as a whole is much harder than the ordinary one, so the shock resistance is worse, the noise is greater, and the driving comfort will be reduced.

Moreover, the characteristics of its tires have higher requirements for vehicle suspension, and the tires cannot absorb vibrations, but will be directly transmitted to the shock absorbers and suspension, which may shorten the life of the suspension system, and the suspension system with better performance can better withstand it.

In addition, the disadvantage of the run-flat tire is that it is much higher than ordinary tires, and once the tire is changed, two tires must be replaced together, and the maintenance cost is high in the later stage. Also, run-flat tires are heavier than regular tires, and heavier tires mean more fuel consumption.
