1, tire type, design characteristics and quality. Different manufacturers produce tires according to different performance requirements. Tire performance includes grip, energy saving, wear resistance, noise and many other aspects. The rubber formula and tread pattern of the tire will directly affect these properties, but no tire can achieve the best in all aspects because some properties are contradictory. Paying attention to only one or a few aspects. For example, wear-resistant tires, rubber formulations generally contain more wear-resistant additives, rubber will be harder, and patterns will rarely have large horizontal stripes. But in this way, the grip of hard rubber tires is obviously not as good as that of soft tires, and the driving noise will be too high. Hot-melt tires are mostly used for racing tires, which are extremely soft. What is more exaggerated is that they are in a semi-molten state when they reach the normal optimal working temperature, so that the tires are completely close to the ground and minimize out of control. Therefore, these tires have excellent handling performance and are necessary for racing cars (in fact, you will often notice that there are many spare tires in the team's maintenance station, and they are all wrapped in something, which is actually an electric heating bag to keep the tires at the optimal temperature at any time). At the same time, the car will have a warm-up circle before the start of the race, and you will see all the cars swing back and forth. In fact, this is also heating the tires. However, its shortcomings are also obvious, because it is too soft and has great wear and tear, and its general life span is several thousand kilometers or even shorter. In the modification of road sports cars, some people use this kind of tire, but it is definitely not worth the loss, because ordinary roads simply can't give this kind of tire space. On the contrary, the semi-melting characteristics of this kind of tire will bring about its own destruction, and even the pebbles on the road will be eaten into the rubber. Of course, this is only a comparative variety, but generally speaking, tires that pay attention to handling and quietness are soft tires, and the wear resistance cannot be too good. Besides, the quality is needless to say. You can consult the master at the tire shop. They will tell you what kind of characteristics your tires belong to. Maybe 30 thousand kilometers is the normal life of this kind of tire.

2. The condition of the vehicle itself. The first is the body structure, such as four-wheel alignment, which should be checked and adjusted regularly. After driving for a long time, the position and torque of each wheel will change slightly. Although it is invisible to the naked eye, it will have an impact on the driving of vehicles and the working conditions of tires. Every car will have a calibration mechanism for this problem, but this can only be done through the locator of a professional repair shop. The other is whether the car is overweight for a long time, such as often pulling heavy goods.

3. Pavement environment. It is very expensive for tires to walk often on gravel roads or rugged roads.

4. Tire maintenance status. Tire pressure is very important. If it is low, it will accelerate the wear on both sides of the tire tread. If it is high, it will cause excessive wear in the middle of tire tread. It should be inflated correctly according to the tire instructions. At the same time, it is also important to avoid the tires from contacting some substances that are harmful to the tires, such as grease. Exposure to the sun for a long time, long-distance parking without moving the position make the tire suffer local oppression for a long time, and also cause damage to the tire.

5. Driving habits. This is the most important factor besides the nature of the fetus. Frequent refueling to accelerate the start, high-speed sudden braking and sharp turning are all important factors to accelerate tire wear.

Therefore, when buying tires, we should consider it comprehensively. It is not appropriate to consider only one aspect of the major. For example, wear-resistant tires are not necessarily good, because the noise is high, the handling is slightly poor, the braking distance is long, and the probability of slipping under sharp turns is high. A tire with good handling has short braking distance and smooth steering, but it will certainly not be the most fuel-efficient ... So, you should choose according to your own situation and car condition, and generally choose the one with balanced performance in all aspects.
