Preface
Hello everyone, I am Neiku.
has been in trouble recently. Tokuhara Ryo, who is driving on a daily basis, crashed. The accident was not serious and it took a long time to repair it. Moreover, there is no scooter provided by the 4S store (I may write a sharing of my experience of accident claims in the future), so I have to drive the 08 Mazda 3 that I am idle recently. Then after two days of driving, I was worried about having a fetal uterine pest. The
tire has been in service for more than seven years. I did not choose to replenish the tire instead of changing it to a new tire. I haven't changed my tires for so long, just because I'm poor and don't want to spend more money on the old car that is about to be eliminated, and it's not that the tires are not important.
tires play an important role in cars, whether it is driving safety or driving experience! It just so happens that the year will be the Double Eleven again, and many car owners will consider changing tires during this period, so they want to talk about some things about tire purchases.
outline is as follows:
1. Why change tires
2. When to change tires
3. What kind of tires should I change
4. What kind of tires should I recommend
1.1. Improve driving experience
Tires As the only part in contact with the ground, it will have a great impact on the vehicle's control and driving experience, such as grip ability, road feeling feedback, tire noise at different speeds... So many car owners will give a feeling of "changing tires is like changing a car" after changing tires of different brands or models.
1.2. Ensure driving safety
tires not only affect the vehicle's handling and driving experience, but also concern the driving safety. So when there are safety hazards in tires, it is necessary to replace them, after all, there is no small matter of safety.
1.3. Natural law of consumables
tires are consumables. As long as they are consumables, they cannot violate their natural law. As the strength and use time increase, they will wear and age until they are replaced... Generally speaking, it is recommended that the service life of the tires of the main model of everyone should not exceed 5 years.
2. When to change tires
2.1. Natural aging of rubber
In addition to the situation where the tire is broken and cannot be replenished, tire aging should be one of the most common situations when car owners need to change tires. Generally, they are prone to cracking, peeling and other problems in about five years. Once this happens, you need to replace the tires in time.
2.2, crown uses wear
All civilian tires have corresponding wear limit representations, that is, the raised sign located in the groove. Once the tire blocks wear and are basically flush with the wear limit sign, the tire will reach the end of life. From a safety perspective, it must be replaced.
2.3. Multiple tire ticks affect safety
△ It’s time for me to appear again...
Generally speaking, when I encounter tire ticks, just choose to repair the tire. However, if the same tire is tied multiple times, even if the tire repair operation is performed, the safety of the tire will be greatly reduced. At this time, it is more recommended to replace the tire directly than the sewing and repair operation!
2.4. The tire walls are bulging and damaged. The side walls of tires are relatively weak. Especially for tires that pursue comfort, the tire walls are generally soft. They can easily cause side bulges when passing through pits, speed bumps, or often hard on the street. Once the bulging problem occurs, the bulging will be unable to withstand the tire pressure, which will intensify the possibility of tire blowout, and there is no regularity at all! Based on the uncertain risk of tire blowout, it is recommended to replace it as soon as possible once the bulge occurs. 3. What kind of tire should be replaced with
3.1. Sharp control?
Car owners who drive more aggressively often hope that the tires can have better grip, so a sports tire that focuses on handling is more suitable. At the same time, the stronger grip of sports tires can also improve braking performance, shorten the brake distance, and be more at ease when encountering emergencies. But most car owners here do not need this kind of control tires. After all, we don’t have much time to play 0-1 acceleration and try not to make any moves on the road.There is a single and narrow target group for the control tires, which is a bit similar to the consumers who are playing manual transmissions now.
3.2. Wear-resistant and durable?
Unless it is an online car-hailing or taxi with a very high mileage every year, ordinary household cars do not need to deliberately replace wear-resistant tires, because the aging period of rubber is approximately 5 to 7 years. Based on the mileage of 10,000 to 20,000 kilometers per year, very few household cars have to replace tires because of wear and tear. On the contrary, it is more because of the aging of rubber. Therefore, except for special circumstances, there is no need to specifically pursue wear-resistant performance.
3.3. Silent and comfortable? Compared with handling and durability, when choosing tires for ordinary household cars, the silentness and comfort of the tires have a great impact on driving experience, and it is also the main struggle between major tire brands in the home field.
According to friends in the tire industry, in the Chinese market, in various performance orientations, the sales of silent and comfortable tires have always been higher than those of wear-resistant, handling, off-road tires, etc.
Moreover, the silent tire category is destined to flourish: now the number of new energy vehicles in is getting bigger and bigger. With less engine sound, the presence of tire noise becomes stronger and stronger, and changes are bound to be made.
3.4. The master of the ensemble - silent cotton tire
. I believe that every car owner hopes that the tire can have better handling, comfort, tire noise and service life. But you cannot have both fish and bear's paw. After the tire technology iteration in recent years, silent cotton tires have reconciled the contradiction between the above performance indicators. Before
, tires could only achieve different effects through different "rubber formulas" and "pattern design". If you want to be comfortable, the rubber must be soft, and if you want to be wear-resistant, it must be hard. There are also some tire brands that can reduce noise through pattern optimization, but it also brings the problem of weakening grip. After adding the additional noise-silence and noise reduction capabilities of "silent cotton", the tire rubber formula and pattern design have more room to take into account wear resistance and handling, and improve the other two indicators without sacrificing comfort.
But most of the current silent cotton tires are expensive.
, on the one hand, uses new costs brought by new technologies; on the other hand, the comprehensive performance of tires is stronger, and tire manufacturers should increase the price; in addition, many manufacturers use silent cotton tires to set up the flags of high-end product lines, which are generally not suitable for the size of ordinary family cars.
For example, the Michelin PS EV series used on Tesla Model Y, the price of 4 pieces is about 10,000 yuan. More car owners with sizes such as 205 55 R16 cannot experience the PS EV series even if they have a sufficient budget.
, but there are exceptions. This time I will focus on several excellent silent comfort tires. Tires with silent cotton technology will be specially marked.
4. Multi-brand tire subjective recommendation
4.1, Michelin PRIMACY 4
silent cotton configuration: ×
No matter whether there are too many brand premiums, choose tires, Michelin is still a brand that cannot be skipped, especially in terms of silent comfort characteristics, its reputation has always been very good. For example, Michelin's PRIMACY 4 (Haoyue 4), Haoyue focuses on silent and comfortable, and 4 represents the fourth generation. In addition, Haoyue 4's slippery road grip is also one of the buying points. Last year, my Deyuan Lang replaced this PRIMACY 4...
As mentioned above, the silent design of Haoyue 4 mainly involves two aspects: pattern and rubber formula. Silent ribs are designed in the center and shoulders of the tire to reduce the air vibration when the tire block deforms during driving, thereby achieving the purpose of noise reduction.
In addition, the comfort of Haoyue 4 is also reflected in the "soft" of the tires. Before replacing Haoyue 4, the Dunlop SP SPORT 01 of the original car was clanging and clanging when pressing the manhole cover. After replacing Haoyue 4, the experience has increased significantly by at least one level.
Of course, this also means that Haoyue 4 has to make sacrifices in wear resistance. Its wear resistance index (TREADWEAR) is only 340, and its wear resistance is not strong. Car owners with relatively high annual mileage need to pay attention.
4.2. Continental CC6
silent cotton configuration: ×
German brand Continental CC6, also has a well-known silent and comfortable tire.
's unique secrets include the circular frequency converter denoiser in the groove and the tread silencer design. The former is used to break the noise generation in the groove, and the latter is even more open-ended design to change the pattern as a prerequisite for closing the sound cavity. Both methods are used to reduce noise from the source of the pattern, so the silent effect is outstanding.
4.3. Goodyear Yucheng third-generation
silent cotton configuration: √
Goodyear Yucheng series is also a very famous model among comfortable oriented tires, and this year it launched the third generation of products. Compared with the previous generation products, the pattern of Goodyear's 3rd generation is finer, which is used to reduce the pump noise generated by the compression deformation of the pattern and reduce noise from the source. The difference between
and Michelin PS EV is that this layer of silent cotton in the third generation of Yucheng is not placed inside the tire for everyone to see and touch, but is directly integrated into the tire. A sandwich layer is added between the nylon layer and the rubber layer to block the tire rolling noise and reduce the transmission of road vibration. According to Goodyear , the overall idea of ANX noise reduction technology and the same principle as silent cotton sound absorption and noise suppression. However, because it is in the intermediate layer, the thickness is limited, and "qualitative change" cannot be formed through "pile volume".
4.4. Thunder Jingyue
silent cotton configuration: √
This Thunder Jingyue tire has also been very popular recently. It has more than 5,400 positive reviews on the Tuhu APP. Because the size adaptation is very popular and the price is not expensive, it can be called a popularizer of silent cotton tires. The main feature of the entire Thor Tire series is silent cotton. Whether it is the high-end air-saving series or the more popular Jingyue series, they all focus on silent cotton configuration.
Judging from the front Continental CC6 and Yucheng 3rd generation patterns, their patterns are more finer, thereby reducing pump noise, but the disadvantage is that they will lose a certain amount of handling and drainage performance. The design idea of Thor tires is different. It adopts a multi--pitch pattern design. Since a single noise frequency is easily perceived, designing more sound frequencies can make the noise difficult to perceive. Thunder God Jingyue has designed 5 types of blocks to reduce auditory fatigue. To give an unrigorous example, listening to the sound of cutting steel bars and listening to a 5-tone nursery rhyme " Two Tigers ", of course, the former is even more annoying. Judging from the pattern, Thunder God Jingyue uses 4 wide drainage grooves, which also takes into account the grip of wetlands.
△Thunder God Jingyue’s pattern design, the picture is from Tuhu APP, the key to deleting
is still thick silent cotton. The silent cotton of Thor tires is placed inside the tire, which is a visible and tangible design (the red circle in the picture below is the red circle).
△Picture source Tuhu APP, delete
As mentioned above, through the blessing of silent cotton, you do not need to rely solely on tread patterns and soften rubber formula to achieve silent effect. There is more room for pursuing other performances, thereby achieving better balanced performance.
In terms of the 3T index, Jingyue's traction index (TRACTION) is A-class (suboptimal), the temperature index (TEMPERATURE) is A-class (optimal), and the wear resistance index (TREADWEAR) reaches 520, which means its design mileage life exceeds 240,000 km. This indicator is not inferior to some tires that focus on wear resistance, and gives car owners with high mileage in those years a new choice.
4.5. Pivot Statics S1
silent cotton configuration: √
Compared with Thor's silent cotton tires, the fulcrum tire has a higher positioning, which further strengthens the grip and silent performance, and has also made breakthroughs in the appearance design of the tire.
You may also think that the black tires are black. If you have any appearance designs, let’s start with the appearance. Like people, even if they wear suits and tie, if their shoes are not properly taken care of, they will give people a much worse impression.When the tire loses its bright and dark luster and becomes grayer, it always makes people feel that the whole car is not energetic, so every once in a while, I will spray tire glaze, not for maintenance, just to make the tire look more energetic. However, this has become an extra cost...
The current tire technology has been rolled into the appearance design. In fact, many new products in mature fields are inevitably rolled into the appearance. If the Dyson hair dryer is made into the Panasonic , I think everyone is unwilling to pay for it. The feeling of fulcrum tires is a bit like the Dyson in the tire field, taking into account both technology and appearance.
uses the "lunch" velvet process on the sidewall of the fulcrum tire, so that the tires can maintain a bright and black luster for a long time. The actual loading photos are very good. In terms of performance of
, fulcrum also focuses on silentness. In addition to traditional silent technologies such as closed shoulder , multi-frequency variable pitch patterns, rubber formulas, silencer/holes, the fulcrum tire has added the "Wanda OneLife" silent technology, that is, the polyurethane silent cotton inside the tire cavity is used to absorb and block the cavity noise and tire pattern deformation noise generated by the tire rolling, reducing tire noise to a greater extent.
4.6. Dongfeng Yingji YJ-01 series
silent cotton configuration: √
Among the domestic tire brands, Dongfeng has always been a very cost-effective existence. To the latest silent cotton tire track, Dongfeng's Eagle Strike YJ-01 is still a representative of cost-effectiveness, or it should be said to be the most cost-effective choice at present.
also suits all kinds of models, including various models with 205 tire widths. I have searched for a certain tiger and it is the lowest price among silent cotton tires.
Through the above picture, you can also see the pattern design characteristics of Dongfeng Yingji 01 series silent cotton tires. The wide drainage tank suppresses the formation of water film and ensures the drainage performance of wetlands. The pattern is a variety of pitches and open designs, and it is also a design idea for source noise reduction.
5. Summary:
Finally, let’s talk about the 6 brands mentioned above. Everyone should have discovered that there are traditional foreign brands and new tire brands. There has always been a lot of discussion about the choice of two brands (for example, Mercedes-Benz or NIO , Panasonic or Dyson...), I will also talk about my point of view:
First of all, China's tire industry is large enough and is also moving towards a big to strong process. Judging from the technical layout of this wave of silent cotton tire brands, Chinese brand tires are also "overtaking on the curve".
Secondly, tires are related to driving safety. No matter new or old brands, they must pass relevant domestic and international standard tests before they can be launched. Take the Thor Tire 3T index mentioned earlier as an example. This is an American DOT standard, and the brand has also taken care of. Interestingly, when you ask about the customer service 3T index of some foreign brands, the other party often talks about it. New brands have relatively fewer premiums, which is why I recommend 3 models.
The annual Double Eleven is right in front of you. If you just consider changing tires during this period, I hope this article will be helpful to you.
This is all for this sharing. I am Neiku, see you next time!
