Which is more reliable, self repairing safety tire or explosion-proof tire?

When driving on the road, it's hard to avoid the tire being punctured. What's more, if the speed is too fast, the tire will burst, threatening your life. According to the national traffic data, nearly 70% of high-speed fatal accidents are caused by tire blowout. Once the high-speed front wheel has a tire blowout, the mortality rate is close to 100%. At the same time, on average, one person dies every 6 minutes due to a flat tire. Every year, more than 100000 people die from a high-speed flat tire! The death toll of tire explosion is 26 times that of fire. The bloody data makes more people pay attention to tire safety, and explosion-proof tires have become the choice of more and more car owners. What is "explosion-proof", from the perspective of product naming, is a tire with the function and measures of preventing tire burst, rather than a tire that "prevents tire burst". At present, there are two types of so-called explosion-proof tires in the market: one is the traditional tire for air shortage protection, which is also called zero tire pressure continuous driving tire; One is a new self repairing safety tire, which is better? I will summarize the principles and characteristics of the two.

First of all, the traditional tire for air shortage protection

As the name implies, the tire for air shortage protection is a tire that can still be used in a short time after air leakage or burst, but the tire for air shortage protection is not explosion-proof! No explosion proof! No explosion proof! It's important to say three times that the tire for air shortage protection does not have any function and measures to prevent the tire from bursting. Instead, it is the function of a compensation measure taken after the tire burst, that is, whether the tire should burst or not. Therefore, this product is still controversial at present. The tire of any brand does not dare to bear the logo of "explosion-proof tire". Instead, it is expressed by such scientific names as flat tire, zero tire pressure continuous running tire, run on flat or RSC. The "explosion-proof tire" is verbally called out by the tire agent dealer. 

Advantages of traditional tire with air shortage:

1. In case of tire blowout and air leakage, the sidewall can provide certain support to the tire, so that the tire will not be separated from the hub, resulting in instantaneous change of center of gravity and vehicle rollover, which improves driving safety to a certain extent;

2. After the tire is punctured, it can continue to drive at a speed not higher than 80km / h, and find the nearest maintenance point for maintenance;

Disadvantages of traditional tire with air shortage:

1. If the running speed exceeds 80km / h or the running distance exceeds 80km after the tire is out of air, the tire is also scrapped and cannot be used again;

2. Because the support body is added to the sidewall structure, the hardness and toughness of the whole sidewall are enhanced, and the mute effect and shock absorption effect are poor;

3. Two preconditions must be met for the installation of tire for air shortage protection: ① the vehicle must have a designated suspension; ② The vehicle shall have special rims; If an ordinary vehicle that does not meet the conditions is forcibly installed with a tire for air shortage protection, it is easy to cause damage to the shock absorber;

4. Due to its special material and hard sidewall, professional tire stripper must be used during replacement. It is difficult to maintain and the maintenance cost is high. Basically, it is only replaced but not supplemented.

Then we talk about the new self-healing safety tire

It is not hard to see that the self repairing safety tire has more advantages:

1.The i-Sealing technology coating (polymer nano memory synthetic material) for self repairing safety tires has a memory self-healing function, which can quickly wrap sharp objects with a diameter of less than 6mm into the tire tightly without air leakage; When sharp objects are pulled out, the perforation is filled and sealed, so that there will be no air leakage or slow leakage after the tire is punctured. Even when driving over sharp objects at high speeds, the technical coating can serve as a buffer protection, preventing the pressure from being instantly released at the tire wound, effectively preventing tire blowout. After comparing the high-speed explosion-proof function of Honghai's self repairing safety tire and ordinary tires, it was found that ordinary tires burst immediately when they hit the tire breaker at 120 yards, while Honghai's self repairing safety tire continued to drive in a straight line after passing the tire breaker at 120 yards, without any air leakage or tire blowout, The on-site effect is stunning; And ordinary nails that do not leak are even more pediatric;

2. The overall material of the self-healing safety tire is more elastic. The protective coating on the inner side of the tread can reduce the vibration feeling of the vehicle during driving, and make it have a certain sound absorption effect. The shock absorption and mute effect is far better than that of the flat tire, especially when driving at high speed;

3. The self repairing safety tire product does not change the sidewall structure, so it can be installed without adjusting the suspension and wheel hub of the vehicle. The degree of adaptation is much higher than that of the flat tire, and no additional modification costs will be incurred. In general, it has more price advantages than the flat tire;

4. Some self repairing safety tire brands even provide a one-year warranty, saving the cost of tire replacement and no after-sales worry;

How to choose a self repairing safety tire?

At present, the self repairing tire manufacturers in the market generally have no technical research and development ability, and still use traditional glue sprayers and hot-melt adhesives to spray the rubber on the inner wall of the tire. The softening point of this hot-melt adhesive is usually around 70-80 degrees. In summer, it is very easy to degumm and flow, and the internal coating will crack when the temperature is around 0 ℃. This not only does not play a protective role, but also brings new safety risks to the vehicle, Therefore, in the selection of self repairing safety tires, we must identify manufacturers with formal qualifications and research and development capabilities.
