What are the significant impacts of tires on car safety?

1. Support the full weight of the vehicle, bear the load of the car, and transmit the force and torque in other directions;

2. Transmit the torque of traction and movement to ensure good adhesion between the wheels and the road surface, so as to improve the dynamics, dynamics and passability of the car; Together with the automobile suspension, it mitigates the impact of the car when driving, and attenuates the resulting vibration;

3. Prevent auto parts from severe vibration and early damage, adapt to the high-speed performance of the vehicle and reduce the noise during driving, and ensure the safety, handling stability, comfort and energy-saving economy of driving.

Hello! The tires are the only part of the car that comes into contact with the ground. It is the most important investment for drivers in terms of safety.

The tread width, aspect ratio, speed coefficient, load factor, tread condition, wear, tire balance, and wheel alignment of tires are all related to the performance and safety of the car.

There are other influences, such as vehicle dynamics (e.g., top speed, etc.), economy (e.g., fuel consumption), noise, braking efficiency (related to tire grip), comfort, etc. Hope!

The safety of a car may be measured by many people by comparing superficial equipment lists and how many stars the car can get in crash tests, but very few people really pay attention to the only part of the car that is in contact with the road - the tires. For the safety of a car, the most critical factor is actually the tires, and equipped with a good tire can greatly improve the safety of driving.

The first is grip, which is known as the premise of all active safety systems. In the past, the first thing that may have come to everyone's mind was the ABS anti-lock braking system, but in recent years, there have been many driving assistance systems to help us improve safety, but we don't know that the most important thing is the grip of the tires. For example, when it comes to waterlogged roads or special road conditions, all those systems and technologies also depend on the grip of the tires, so it's best not to ignore this.

The second is the operability of the car. If a car is well handled, it can allow the driver to fully experience the pleasure of driving, otherwise it will be greatly reduced. And this operability also depends on the quality of the tires, good tires will make the driving smoother and reduce your safety worries.

Therefore, you should never ignore the importance of tires when buying a car.

1) Transverse pattern: The traction, braking force and cleaning ability of the tires using this pattern are better, but the disadvantage is that the lateral resistance is small, easy to slide, and the noise is large.

2) Longitudinal pattern: The tire with this pattern has low rolling resistance, is not easy to slide sideways (good lateral grip), and can provide good handling stability for the car, but the driving force and braking force are worse than those of transverse pattern tires.

3) Longitudinal and horizontal pattern: It has the advantages of both longitudinal and transverse patterns, which can not only provide good handling performance for the car and prevent side skidding, but also provide good traction performance and braking performance.

4) Block pattern: It is characterized by the fact that the pattern grooves are connected to each other, showing an independent pattern block structure, which has superior braking and handling performance, and can obtain strong driving force and braking force, especially suitable for snow and wet roads. However, it has poor wear resistance, high resistance when driving, and high noise.

5) Mixed pattern: It is characterized by a narrow pattern groove in the middle of the tread with different directions or mainly in the longitudinal direction, and a wide pattern groove with different directions or transverse on both sides. Such a pattern collocation makes the mixed pattern have good comprehensive performance and strong adaptability, and its adhesion performance is better than that of ordinary patterns, but the wear resistance is slightly inferior.

This must have a great influence, it must all affect each other, and this is multifaceted.

In dry conditions, there is little difference in the coefficient of friction between cement pavement and asphalt pavement, but after rain, the difference is larger. The friction coefficient of normal dry asphalt pavement is reduced to that of pavement in rainy days and snow pavement, and it is lower in icy pavement.

The role of tires

First, the tire is the carrier of force transmission between the vehicle and the road surface, and the driving force, braking force, and steering force are transmitted through the tire, so as to realize the driving, braking, and steering operations of the car.

Second, support the vehicle load. The load on the vehicle causes the tire to sink until the average pressure of the tire contact area is balanced by the inflation pressure inside the tire.

Third, reduce and absorb the vibration and impact force of the car during driving, and avoid early damage caused by violent vibration of auto parts. At the same time, it adapts to the high-speed driving state of the vehicle and reduces the driving noise to ensure the safety, comfort, handling stability and fuel economy of driving.

The performance of the tire.

As the only part of the car in contact with the ground, the performance of the tire directly affects the safety of the driver and passengers of the vehicle, and the importance of tire performance can be imagined.

With the rapid development of the automotive industry, consumers have begun to pay attention to the comfort, handling stability, NVH and other performance of the whole vehicle in addition to the performance of the tires.

The first category is the safety performance required by regulations: high speed, durability, detachment, strength, outer edge size;

The second category, the performance from tire assembly to vehicle testing: comfort, handling stability, NVH, fuel economy, impact resistance, dry and wet braking performance, wear performance, etc.;

The third category is the performance test of the tire on the tire: static grounding pressure distribution, rolling resistance, tire rigidity, tire cell noise, tire mode, prat, six-component force test, odor, air tightness, environmental protection, tire dynamic balance uniformity, etc.

As a vital component that affects the driving safety of automobiles, automobile tires should be purchased through formal channels. When buying tires, you must go through official channels, preferably to a large auto parts store or a brand tire store. If you buy online, it's best to choose a larger *** or an official store.

When purchasing, it is necessary to carefully check whether the packaging is complete, because the brand tires produced by regular manufacturers will be marked with tire model, performance and other information when leaving the factory, and there is no difference between the tread and the sidewall void.

1.Although the state has no special regulations on the shelf life of automobile tires, the shelf life of tire rubber is generally 3 5 years. Even tires that have not been used before, after this period, the rubber and cord will age, the steel wire will rust, and some fine cracks will appear on the surface of the tire, causing the tire to weaken.

Due to the strong sports performance, the asymmetrical tread pattern is mainly used as the tread pattern design of sports performance tires, and there are generally tires specifically for sports performance cars and sports SUVs.

2.The tread pattern of the tire is directly related to the handling performance, and different tread shapes directly affect the handling performance of the vehicle. We should choose the right tread tires according to the road conditions and speed that the vehicle is often used for vehicles, trucks, buses, etc.

For medium-speed driving on general hard roads, it is advisable to choose large tires with horizontal or vertical and horizontal patterns; For vehicles that often drive on highways and good hard roads, it is recommended to choose small tires with good heat dissipation and strong lateral stability with both longitudinal and longitudinal patterns.

3.Generally, genuine new tires will have anti-counterfeiting marks, which will be affixed to the tire's trademark. Moreover, there are many anti-counterfeiting methods at present.

In addition to the number of scratches on the coating, there are also watermarks and barcodes on the trademark, which can be used as a way for us to identify the authenticity of the tire. The purchased tires should be loaded in time, and the air pressure should be sufficient according to the regulations. Check the tires for lumps or cracks after they are inflated.

If you don't know the tire size and parameters, be sure to consult a professional and ask yourself about the most suitable tires for your car, so as to ensure that you buy the most suitable tires for your car. The above is the answer to the question of how to buy tires as a vital component that affects the driving safety of automobiles.

When buying tires, we must first look at whether the tires are the original manufacturers, but also look at the tire pattern, look at the tire pressure, look at the various indicators of the tire, and look at the parts of the tire.

First of all, it is necessary to see whether it is a brand tire, but also to see the production date of the tire, to see the flat ratio of the tire, to see what the tire pattern is, and to pay attention to whether the contact area between the tire and the ground is very slippery, and also to observe whether some small details of the tire are exquisite.

When the tire structure should pay attention to the choice of original tires, the comprehensive performance of the original tires is relatively high, and you can also look at the brand to choose tires, the grip of brand tires will be better, and more durable.

<><1.Abnormal tire pressure

The tire pressure is directly related to the comfort of the car, if the tire pressure is too high, it will cause the contact area between the tire and the ground to become less resistant, followed by the friction of the accelerated contact surface, in addition to the tire pressure is too high will also increase the risk of puncture. And what happens when the tire pressure is too low? It will increase the contact area between the tire and the ground, and will reduce the functionality of the rubber, so that it will cause delamination or cord breakage, and increase the wear of the entire tread.

2.Aging cracks continue to be used

Crack is the inevitable aging phenomenon of rubber products, with the increase of use time, cracks will gradually appear on the tire, with the deepening of cracks, will gradually reduce the stability of the tire;

It's easier to show at high speeds. Cracks can also increase the risk of punctures, so you should carefully check the aging of your tires every once in a while.

3.Gravel is not cleaned

Due to the characteristics of the pattern on the tire, so that the tire will inevitably be stuck in the pattern gap in the process of driving, some riders feel that the pebble will not affect the performance of the tire, feel that it doesn't matter, but the pebble will reduce the grip and drainage of the tire, resulting in a serious challenge to the balance of the vehicle, in addition to the pebble will also make noise. Therefore, for the safety of the car and the service life of the tire, it should be cleaned in time; The clean-up method is also very simple, just use a key or pendant, but try to avoid using sharp tools.

4.Put the steering wheel in place

If the turning is difficult, because the speed cannot be controlled, the scumbag will stop and adjust the steering wheel before starting. Frequent slapping of the steering wheel on the spot will lead to a sharp increase in the wear of the contact surface, and in the long run, the tire will bulge, greatly reducing the life of the tire.

5.The road teeth

Don't underestimate this road tooth, on the lethality of tires, the road tooth is the first iron hit, you don't need to rush to the road tooth many times, it is possible to reduce the dimension of the car at one time. In the process of the tire rushing to the road teeth, as the tire rises, the pressure will gradually gather to a point of the tire, if the road teeth are sharp, it is likely to tear the cord of the tire, causing bulging phenomenon. Therefore, remember not to hit the road.

As one of the important parts of the car, the tire is directly related to the safety of our driving fiber, the service life of the tire generally has a service life of three to five years under normal circumstances, ignoring the maintenance of the tire and bad driving habits may lead to a great discount in the use of time, so which driving habits will cause our tires to be harmed, summarized the following points, let's take a look at it with you.

Tire pressure. For vehicles without tire pressure monitoring function, many car owners will not take the initiative to check whether the tire pressure is normal, generally speaking, the tire pressure of civilian vehicles is between the trouser slots, which is a normal value. If the tire pressure exceeds, the unit pressure in the middle of the tread will increase and bulge, the wear in the middle of the tread will be aggravated, and the tire pressure will be too high to make the middle of the tread bulge, which will not only accelerate the local abnormal wear of the tread **, shorten the service life of the tire, thereby reducing the life of the tire.

Cracked tires.

As mentioned earlier, tires are consumables, and rubber will age due to the time and environment in which it is used. If the tire cracks, the stability of the tire will deteriorate, especially during high-speed driving, and the increase in tire pressure will have the potential potential danger of puncture. In such cases, it is necessary to replace the tires in time.

High-speed passage through uneven terrain.

Road conditions affect the service life of tires to a large extent. The average household vehicle is equipped with road tires. If the tire is damaged at an early stage, the life of the tire will be shortened.

In particular, rough terrain not only exacerbates tread wear, but also causes impact on tires. The tire will be seriously deformed under the huge impact force, and the internal pressure will increase instantaneously, which is the direct consequence of causing the sidewall cord to break and cause bulging, if this situation lasts for a long time, the tire is easy to "lose life".

Put the steering wheel in place

When the vehicle is stopped, the vehicle weight will be concentrated on the tires. At this point, turning the steering wheel into place will increase the friction between the tires and the ground, resulting in local damage to the tires and increasing the wear and tear of the tires. When the tires rotate in place, the resistance increases, and the working pressure of the power steering system should increase several times to assist the steering.

Frequent operation can also shorten the life of the power steering and increase its failure rate. The correct thing to do is to release the brakes and slowly hit the steering wheel.
