I have installed imported tires, but also used domestic tires, after a comparison, I found that the choice of tires should not only look at the brand, but also should pay attention to the 6 major performance of the tires, tire selection is not good, light tire burst mistakes, heavy car destruction, only understand the real difference between each brand of tires, in order to choose the brand tires that meet their own requirements!
In terms of choice, the major brands of tires at home and abroad add up to hundreds of kinds, which simply makes us pick eye-catching, and in terms of sales channels, the same products are different prices, and the prices of e-commerce channels and physical stores are very different, which simply makes us real and false, so next we will discuss the 6 major indicators of tire selection!
Tire selection should pay more attention to the 6 major performances
Tires as the only medium of contact between the vehicle and the ground, directly related to the safety of the life of the driver and passengers, but many car owners in the choice of tires, often only pay attention to the price of tires, whether wear-resistant, and how long to run these simple problems, do not know the choice of tires, should refer to these 6 indicators!
Before choosing a tire, we first need to pay attention to the "3T" index of the tire (the 3T index is generally above the tire size). That is, the wear index (TREADWEAR), traction index (TRACTION) and high temperature resistance (TEMPERATURE), followed by the need to pay attention to the speed level of the tire, and finally need to see the rolling resistance level of the tire!
1, wear index is a measure of tire mileage and time length of a major standard, generally in the tire side have a clear label, wear resistance of higher tires can not only save the owner of the silver, but also to the world environmental protection to contribute, according to statistics, the mainland annual production of tire loss of 640,000 tons of oil, and there are 2.5% of particulate matter in the air is caused by tire wear, so today's tire companies are to energy saving and environmental protection as the main production goal.
In general, the wear index of family cars above 300 is basically enough, if the pursuit of extreme wear resistance, wear index needs to reach more than 400.
2, tire traction index, also known as anti-wet slip ability, is the representative of tire safety performance, the better the anti-wet slip performance of the tire, which means that the better the grip of the tire, the less likely the vehicle is to slip, the shorter the braking distance, it is no exaggeration to say that if in extreme cases, even if the braking distance of 1 meter is reduced, it may save countless lives.
The anti-wet slip ability of tires is generally divided into four levels: A/B/C/D/E/F/G, of which the A level of wet slip resistance is better.
3, high temperature index represents the stability of the tire for a long time, as we all know, long-distance tires will be due to the influence of ambient temperature, braking system temperature and other factors, resulting in the rise of tire temperature and air pressure, so the higher the high temperature resistance level of the tire, the better the stability.
The high temperature resistance grade of tires is generally divided into three grades: A/B/C, of which C is the minimum standard for tire production, and A/B level is higher than the normal experimental standard.
4, speed level, speed level indicates the maximum speed of the tire can travel safely, so the higher the speed level, the better the performance of the tire, we can also judge according to the speed level when choosing.
5, rolling resistance, rolling resistance is mainly because of the asymmetrical deformation of the tire in the driving process, the lower the rolling resistance level, the better the fuel economy of the tire, but at the same time it also loses a certain amount of grip and braking effect, the popular point is to improve the air pressure of the tire, reduce the deformation of the tire can also achieve the effect of reducing the rolling resistance.
Rolling resistance is generally divided into A/B/C/D/E/F/G these 7 levels, the higher the level, the lower the rolling resistance, the better the fuel economy of the tire, the most intuitive feeling to the owner is more fuel-efficient!
6, silent, that is, the Michelin tires that are known for their comfort and silence, their noise is about 70-78 decibels, so as long as the tire noise is in this range of brand tires, its performance will not be too bad.
Speaking with data, compared with 33 domestic and foreign tire brands, including 21 mainstream domestic tires
In 2020, In the "China TOP Tire Test List", based on the tires of the 215/55/17 model, 33 kinds of domestic and foreign brand tires were tested, including 21 domestic brand tires, and it is not difficult to see from the data that the gap between domestic brands and joint venture brand tires is getting smaller and smaller.
In order to ensure the fairness of the test, all the tires purchased this time are purchased directly from the market, not the samples provided by the manufacturer, and the tires of the 215/55/17 model are the models with the largest shipment and the most matching, so they are very representative, and then let's take a look at the gap between each tire from the data.
1. Market price
From the above picture, we can find that the same model of 215/55/17 tires, the price of the joint venture brand is more than 500 yuan, especially Michelin, it is close to 700 yuan; and the price of domestic brand tires is concentrated below 500 yuan, the cheapest Haohuacai 267 yuan, so in the face of the same quality, the price of domestic brand tires is more advantageous.
According to the above comparison table, we select the first 5 cheapest domestic brand tires for reference: Haohua Tire > Changfeng Tire> Triangle Tire> Wanda Baotong Tire> Fengyuan Tire > Xingyuan Tire
2. Tire weight
The so-called "spring on a kilogram, under the spring ten kilograms", is to say that the weight of the vehicle performance of the improvement, so a tire in addition to wear-resistant fuel saving, weight is also very important, so now many tire companies began to pay attention to the lightweight design of the tire, and the most intuitive reflection is in the weight of the tire, so the next we compare is the weight of the tire, in fact, from the data point of view, The average weight of joint venture brand tires is 10.39 kg, and the average weight of domestic brand tires is 107.4 kg, and the difference between the two is not very big!
From the above figure, we can see that the heaviest is Pulin Chengshan, reaching 11.82 kg, and the lightest is Kumho Tire, reaching 9.94 kg, so take the top five brands of the lightest tires as a reference: Kumho Tire > Zhongce Tire > Changsheng Tire > Yanchang De antong Tire > Haohua Tire.
3. Comparison of tire "3T" index (wear index, traction index, high temperature index)
To judge the quality of a tire, we also have to look at the "3T" index of the tire, so next we will compare the static data of the major brands of tires.
From the above picture we can see that the wear index of domestic brand tires is generally relatively high, generally speaking, the wear index is higher than 400 is a more wear-resistant type, and the traction index and high temperature index of major brand tires are basically above A, the gap is not very large, considering that these three parameters are not mandatory requirements of the national standard, so there may be a case of false labels, so these three parameters we only use as a reference, so take the top 5 brand references of wear resistance: Sen Qilin > pullback > extend the deAntong > Xingyuan > Wanda Baotong.
4. Speed level comparison
For performance cars, the pursuit of high-speed driving and extreme driving, so there are high requirements for the maximum speed that tires can withstand, in theory, the higher the maximum speed that tires can withstand, the stronger the performance of tires.
From the above figure, we can find that the highest speed level of the brand is the triangle TH201 and Linglong AR200, reaching the Y level (300km/h), these two are domestic brand tires, the speed level of W (270km/h) of the brand has 18 kinds, its Chinese brand occupies 16 kinds, the speed level of V level (240km/h) there are 13 models, domestic brands only occupy 3, simply from the speed level point of view, the advantages of domestic brands are still very large.
In fact, the comparison of these 33 brand tires at home and abroad is not very comprehensive, there are many excellent brands in the domestic brand that deserve our support, such as Chaoyang Tire and Libede Tire, etc., are very good domestic tires, and the point that needs to be emphasized is that no matter which brand of tires of which size, there are many kinds of patterns for consumers to choose, there are focus on comfort, there is a focus on wear resistance, and there is a focus on fuel saving, so we can not generalize, or that sentence - The best is what suits your needs!
From the actual use of the experience to evaluate the domestic brand tires, the ranking is not in any order
As a tire worker, the most exposed to domestic brand tires is Taiwan Province's Zhengxin tires and Margis tires, both of which belong to the Zhengxin Group, of which Margis has a higher degree of recognition on our side, and The supporting models of Margis are also more, especially in the low-end Korean cars and Ford cars, my overall evaluation of Maggis Tires is the original car matching, the price is still relatively central, and it does not belong to the international big brand at all in terms of product quality and comfort.
In addition, we use more is the morning sun, pull back and triangle, these three brand tires as the existence of the domestic elder level, the recognition of the domestic low-end market is also very high, many customers have taken the initiative to replace the three brands of tires, in terms of price slightly lower than Margis, but the quality of the product is still worth affirming!
Finally, we use more is the main cost-effective low-cost domestic tires, such as Libede, Triangle, Xinghongyuan, Maxima, Shuangfeng, Double Star, etc., too much, these domestic brand tires have a common point, that is, the main low price, tire quality There is no big problem, that is, the carcass layer is slightly lower, the tire is soft and not resistant to collision, but the overall use of the feeling is still very good, the price is generally 1/2 of the international brand or even lower.
The importance of tyres
The "World Road Traffic Injury Prevention Report" pointed out that about 1.2 million people die from road traffic injuries worldwide every year, of which about 50 million people are injured, and the number of casualties due to traffic accidents in the mainland ranks first in the world every year, and is still growing at a rate of 10% per year, and the latest data on puncture accidents, from the "Correlation Analysis of Puncture and Highway Traffic Accidents", the report counts 2484 traffic accidents in Guangzhou-Shenzhen Expressway from 1998 to 2000. Among them, the number of accidents caused by punctures is 848, the incidence rate is 34.14%, and the high incidence of puncture accidents is from April to September every year, and the incidence rate is 56.84%.
From the above data, it is not difficult to find that the safety of tires will be directly related to the safety of the life of every driver and passenger, and there are two reasons for tire punctures, one is the impact of punctures, the other is the puncture caused by the "standing wave" phenomenon generated by high-speed driving, and for puncture accidents, the state will start from January 2021, for all new cars on the market, tire pressure monitoring system will be mandatorily installed to reduce various traffic accidents caused by punctures.
At last
In fact, having said so many major brand tires, what I want to express more is that today's domestic brand tires are not inferior to international brands in terms of quality and technology, the only thing missing is the consumer's recognition and acceptance of domestic brand tires, so I still hope that all car owners can support our domestic brand tires more!
