For automobiles, it is recognized that engines are very important, but tires are also very important. It's like people who have to travel thousands of miles must pay attention to the maintenance of their feet and wear shoes that fit their feet. It is very dangerous if there is a tire failure such as a puncture on the road.

Today, China International Tire Trade Show will talk to you about tires.

Too high or low tire pressure is dangerous!

Pay attention to tire pressure when using tires daily. Maintaining the normal value of automobile tire pressure is the guarantee of vehicle comfort and driving safety.

According to fixed thinking, many people think that tire blowout must be caused by excessive tire pressure, excessive pumping, or excessive pumping, which is very one-sided.

When the tire pressure is too high and exceeds the normal value, it will cause the tire to be too hard and lose its due elasticity and shock absorption ability. Not only will the grip become worse, but the excessive wear of the central tread will also cause uneven tread depth, and the contact area with the ground will decrease and friction The coefficient is reduced, causing the vehicle to skid, bump, and puncture the tires, endangering driving safety.

When the tire pressure is lower than the normal value, the tire becomes softer, the deformation increases, the contact area between the tire and the road surface increases, and the friction coefficient doubles, causing the tire temperature to rise sharply. If the vehicle is running at a high speed, heat will quickly gather together, and the inside of the tire will begin to separate and delamination, which will eventually lead to a puncture.

Therefore, if the tire pressure is too high or too low, there is a risk of puncture. The standard tire pressure, including the spare tire pressure, should be maintained in accordance with the manufacturer's requirements. The tire pressure can be measured with a tire pressure gauge by itself, but it must be measured at the normal temperature of the tire because the result of the measurement in the hot tire state is not accurate.

How to explosion-proof tires?

A friend said that a puncture is so dangerous, so change to a punctured tire to completely solve the problem of a puncture! If you think so, then you really have to take a good look at flat tires. What exactly is a flat tire? What is the principle of a run-flat tire, and why is it "explosion-proof"?

In fact, explosion-proof tires do not literally understand that they will not burst, it is just a common name, and the real scientific name is run-flat tires.

Run-flat tires

As the name implies, it can still be used normally after a leak, so this type of tire is also called a safety tire or a zero pressure tire. The run-flat tires can still safely drive mileage of about 80 kilometers at a normal speed (for example, 80 km/h) under the condition of completely leaking phosgene.

The principle is not complicated. Generally, after a tire has a puncture, the tire loses the support of air and will deflate in the blink of an eye. At this time, because of the downward pressure of the weight, the wheel hub just presses on the flat tire, and the tire will be scrapped by the wheel soon.

The sidewall of run-flat tires is very tough and supportive. Even in the event of a puncture or a sudden deflation, the tire can still provide a certain amount of support to the vehicle, thereby ensuring the safety of the vehicle.

After a traditional tire blows out, the deadliest thing is "instant deflation" and the body will suddenly and violently tilt. If you are running at a high speed and you happen to encounter the driver not holding the steering wheel firmly with both hands, the consequences will be disastrous.

When the run-flat tire encounters a high-speed puncture, in the words of a car owner who has personally experienced such an encounter: the body is just "slightly sinking", the direction is shaking, but it can be grasped in time. Therefore, run-flat tires do have safer performance than traditional tires.

Tire maintenance tips

Although many car owners regularly maintain their cars, they don't know much about tire maintenance. Here are some tips on tire maintenance, to share with you~

1. Regularly check the tire pressure. Both studs and air nozzle leaks will cause the tire pressure to drop rapidly, and hidden dangers can be discovered in time through the pressure check.

2. Pay attention to tire aging. Sunlight or organic solvents will accelerate the aging of tires. Car owners should avoid using organic beauty products such as tire brighteners, and park their cars in a cool place as much as possible.

3. Tires are consumables and need to be replaced every tens of thousands of kilometers. We can refer to the tire wear mark in the middle of the tire main drain groove. When the tire tread is ground to the same level as the wear mark, the tire needs to be replaced.

4. Good driving habits can ensure that the tires are not damaged. If you must pass obstacles such as pits and protrusions, try to slow down and pass.

5. Don't care about tire bulge. If the bulge area is squeezed again, it may burst, which will affect the driving safety of the vehicle.

China Tire expo reminds you that car owners must not take tires lightly, and we must do our best in every detail of safety.
