[100 Questions]Nine Questions on Correct Tire Use (Part 1)Teach you how to prolong tire life

Tires are part of every car and are also one of the consumables of automobiles. Depending on the positioning of use, the service life of tires may be long or short. Performance tires will naturally wear out faster than economic tires. We know that if you fail to use the tires correctly, the life of the tires may be shortened and the wallet will shrink greatly. For this reason, the editor shares nine tips through question and answer, so that everyone can prolong the service life of the tires.

Question 1: Why do you need to check tire pressure often? Does this have anything to do with tire deformation?

The gas pressure in the tire is also the role played by the tire pressure. It is not only responsible for absorbing road vibrations, but also an important contributor to maintaining the rigidity of the tire. Excessive tire pressure will not only make the tire contact surface only the central part, resulting in the central tire. Excessive tread wear will shorten the life of the tire, and the bounce caused by excessive pressure will also reduce ride comfort.

Insufficient tire pressure, in addition to causing excessive wear on both sides of the tire, the outer edge of the aluminum ring will also reduce the protection of tire pressure and increase the chance of directly hitting the road surface, resulting in the deformation and damage of the aluminum ring. More money to replace new rims, but quite annoying. Moreover, if the tire pressure is insufficient, the ground contact area of ​​the tread will be relatively large, which will relatively cause the problem of heavy starting and drag, and the vehicle will also consume more fuel. What's more serious is that insufficient tire pressure will bring about the danger of tire blowout at high speed. This is because the tire pressure is insufficient. When the tire is running at high speed, the recovery speed of the deformed part is not as fast as the rotation speed of the tire, and sometimes the tire is connected to the tire. The abnormal wave-like deformation occurs on the back side of the ground, which is called "Standing Wave" - ​​standing wave phenomenon.

At this time, if the tire pressure is sufficient, the strong standing wave phenomenon due to the rigidity of the tire will not affect the tire life. The amount of deformation increases, and soon the tread rubber and the inner carcass will peel off. The worst outcome is that the tire bursts and the car loses control. Therefore, ensuring sufficient tire pressure is not only a basic requirement to prolong the service life of the tire, but also It is very important to ensure driving safety. In addition, the timing of checking the tire pressure should be measured when the tire temperature is cool. Don't forget this!

Question 2: Four-wheel alignment is performed every time a new tire is replaced. What is this for?

The instrument used to inspect and measure whether there is any problem with the chassis setting is the so-called four-wheel alignment machine. Most car owners have heard the term "four-wheel alignment" before, and they all know that after replacing new tires or shock absorbers, they still need to go through this procedure to allow the vehicle to drive normally, and as long as the chassis parts are worn out, there will be gaps. Wheel alignment will run away, so if you want to know whether there is any abnormality in the chassis structure, it is the fastest and most accurate way to judge from the perspective of four-wheel alignment.

The purpose of four-wheel alignment is not only to modify the car. Generally, the original car also needs to go through the correct chassis positioning process to have a stable vehicle dynamic response, so as to obtain safe high-speed driving performance. In addition to the tire wear rate, it is also easy to put people and vehicles in an unstable driving environment, and the impact is even higher than other auto parts. It is a very important and basic chassis maintenance item.

Incorrect four-wheel alignment angle usually results in fuel consumption and abnormal wear of chassis parts, and the chances of tires eating unilaterally or deforming will also greatly increase, although many vehicles will mostly perform four-wheel alignment when replacing new tires. However, because the positioning angle will run away due to road potholes, bouncing, or the wear and tear of chassis parts, it is recommended to perform four-wheel positioning every 1 year or 20,000 kilometers. , or the chassis has abnormal abnormal noise, shaking, etc., you should also go to the tire shop for inspection as soon as possible to ensure safety. In addition, some car owners who like to set the Camber, it is best not to exceed an angle of more than 2 degrees, so as not to cause the tire to deform.

Question 3: What are the common reasons for a flat tire?

Tire puncture is one of the main killers that threaten driving safety, and it is the easiest and most important job to reduce the chance of tire puncture and ensure that the tire pressure is normal. However, most people do not check the tire pressure every day. You can keep track of tire pressure at any time.

According to a statistic from the Taiwan National Highway and Expressway Bureau of the Ministry of Communications, 70-80% of traffic accidents on expressways are caused by puncture. It will go out of control directly, and there are many tunnels and elevated roads in Taiwan, and the distance between each gate is very long. If a tire blows out in a tunnel or on a highway, or even an accident occurs, rescue is very difficult! It is also because it is not easy to develop the habit of going out to check the tire pressure, so the importance of installing a TPMS tire pressure monitoring system is even more important. Treat it as an investment insurance.

At present, the types of tire pressure monitoring systems can be mainly divided into "indirect" and "direct". "Indirect" can also be called wheel speed sensing, which belongs to the original car equipment. ESP and ESP are integrated together. When the tire pressure is insufficient, the wheel will rotate at a different speed than the other three wheels due to its smaller diameter, so as to know the tire pressure is insufficient and the light on the dashboard will warn the driver. The advantage is that the cost is low, and the disadvantage is that it is impossible to know which round of pressure is insufficient, and it is impossible to know the tire pressure at any time. In addition, the system does not operate when the tires are not rotating. If the tires are inflated when the vehicle is parked, and the vehicle goes out without inspection the next day, it is very likely that the tires have been crushed when the tire pressure is found to be insufficient.

As for the rear-mounted tire pressure detectors sold on the market, they all belong to the latter. This product can be divided into transmitters (tire pressure detectors) directly locked on the valve (outside tire), or replaced The original valve is installed in the tire (internal type) and other two types of products. The external type has the advantages of easy installation and battery replacement, while the internal type has the advantages of accurate detection and more beautiful appearance. Seeds are better than none at all.

Question 4: I often hear the tire master say that the tires need to be adjusted before and after 5,000 kilometers. Why is this?

The main reason why the front and rear tires need to be adjusted regularly is that the tires responsible for providing driving force usually wear faster than the tires that do not provide driving force. It will be faster than the front wheels, and the four-wheel drive depends on the torque distribution of the front and rear wheels.

Because of this, if the tires are adjusted for the front and rear wheels without a fixed period of time, the four tires cannot be worn out at the same time. At that time, two new tires may have to be replaced on the driving wheels, which is not only difficult to manage the replacement of tires. If the two old tires are not used up in the cycle, the glue will age and harden due to the prolonged use, and the grip of the four wheels will be uneven, which is not conducive to the vehicle handling.

As for the tire adjustment method, it is carried out every 5,000 kilometers. In addition to changing the front and rear of the single-guided tires, it is best to remove the aluminum ring, and adjust the left and right tires before installing the aluminum ring, so as to reduce excessive wear. A unilateral situation occurs. However, I would also like to remind everyone that if it is found that the difference between the inner and outer tread depths exceeds 1mm, there is no need to change the left and right sides, because once the replacement is performed, the steering wheel will only be pulled.
