What is a self repairing tire? How is it different from traditional tires?

In recent years, major tire manufacturers have launched a new high-tech product called "anti puncture and explosion-proof tire". Its English name is "self sea lingfire", which is directly translated as "self repairing tire" in the industry. This kind of tire has the characteristics of explosion-proof, leak proof, noise reduction and energy saving.

So, how can the self repairing tire be anti punctured, explosion-proof and can be repaired automatically? Today, tire brother will share with you.

Basic concepts

At present, the technologies used by the self-healing tires of various brands are different, but they usually use a layer of polymer composite material (in the form of soft solid rubber) attached to the inner wall of the tire to achieve air leakage prevention, explosion-proof tire and self-healing after the tire is punctured. That is, when the tire is punctured by sharp objects, the polymer composite material will quickly repair the perforation, so as to ensure that the tire will not leak, will not burst, and will not need to repair the tire, so as to ensure the safe driving of the vehicle.

Core advantages

1. The self repairing tire can not only prevent puncturing and air leakage, but also prevent bounce and cushion tire burst.

2. The self repairing tire has a noise reduction function, which can reduce the noise generated by the tire and the ground, alleviate the vibration of the tire and the ground when driving at high speed, and make the driving more comfortable.

3. The physical and chemical properties of the polymer composite materials used in the self repairing tire are very stable and will not cause corrosion to the outer tube, inner tube and valve core; At the same time, it can also reduce the tire temperature and prolong the service life of the tire.

Comprehensive comparison

Ordinary tire

1. Repair the tire after being punctured (without anti puncturing measures, the punctured hole cannot repair itself and cannot continue to drive);

2. It is easy to be degummed and air leakage after tyre repair (tyre repair with tyre repair rubber strip is easy to be degummed under specific conditions, resulting in air leakage);

3. The tire is easy to burst when driving at high speed (when the tire is running at high speed, the tire is easy to burst due to factors such as tire aging, tire patching, nails, sharp stones, and environmental temperature);

4. Tire replacement is time-consuming and laborious (the tire replacement process is cumbersome, time-consuming and laborious, and there are hidden dangers in changing tires on the highway, especially when it is necessary to change tires on the highway).

Traditional explosion-proof tire

1. After being punctured, you can drive a certain mileage at a low speed (the full name of the traditional explosion-proof tire is "tire for air shortage protection". After being punctured, you can drive within 80 kilometers at a speed of 60-80 kilometers per hour with the help of the reinforced tire wall);

2. The tire will be scrapped if it runs beyond the design mileage without air (if the tire is punctured and runs for more than 80km to 100km, the explosion-proof layer will be severely worn and cannot be repaired and scrapped);

3. Poor comfort (because the explosion-proof tire is added with a steel wire explosion-proof layer, the tire wall is thickened and hardened, so the driving comfort is worse than that of ordinary tires);

4. The use is limited (because the chassis, suspension and hub of the original vehicle equipped with explosion-proof tires have been specially matched and adjusted. If the explosion-proof tires are replaced by ordinary vehicles, the chassis, suspension and hub will be damaged);

5. The price is relatively expensive (because the manufacturing cost of explosion-proof tires is higher, the natural price is higher than that of ordinary tires. According to different brands, the price of explosion-proof tires is generally about twice or even higher than that of ordinary tires).

Upgrade tires

1. The technology is not mature and the process is simple (the "tire upgrading" that was popular in the past few years is actually to install a quick repair rubber on the inner wall of the tire, the technology is not mature and the process is simple and rough);

2. The processing conditions are arbitrary (since the usual "tire upgrading" is manually operated in the tire store, it is impossible to ensure a dust-free environment and the pollution is serious);

3. The quality is not guaranteed (manually upgraded tires are prone to unqualified materials, degumming and air leakage, which may cause safety accidents when driving at high temperature and high speed for a long time);

4. The dynamic balance is not accurate (so the processing accuracy is low, the accuracy of the dynamic balance cannot be guaranteed, and the driving safety is endangered).

Self repairing tire

1. Not afraid of puncturing (after 48 hours of high and low temperature test and nail plate test, the self-healing tire produced by the factory can drive more than 60000 kilometers normally even though the tire body is punctured into hundreds of holes - it can withstand the pinning within 6000 times);

2. No need to repair (based on polymer nano memory adhesive technology, holes within 8mm after being punctured can be automatically repaired in 0.01 seconds, eliminating the trouble of tire repair and replacement, saving time, effort and money);

3. Safety (the strict process flow and structure of the self-healing tire can ensure that the self-healing layer of the tire will not be degummed and deformed, and the tire will not leak or burst after being punctured to ensure driving safety);

4. Comfortable (self repair has the functions of reducing tire noise and bullet proof, and the driving comfort is higher than that of ordinary tires);

5. Durable (self repairing tire can effectively reduce the tire temperature, make the tire more wear-resistant and prolong the service life of the tire).

In addition, since the self-healing tire technology is a new and advanced technology, in order to let users choose with confidence, tire manufacturers generally provide two-year or 60000 km long warranty, and some manufacturers have also insured users with special high-value tire explosion-proof insurance.
