But it doesn't mean that the more expensive the better, and the tires with high prices are generally targeted.
1000 tires are more expensive in the brand. Compared with 200 tires, 1000 tires are more expensive in the brand.
The same apple, the one that hit Newton on the head, is called "the fruit of wisdom on the tree of wisdom"; If it hits me on the head, it may be a cell phone, right?
Take the specification of 2 15/50R 17 as an example. The official price of Michelin PS4 tire is 929 yuan 1.
The same unknown tire is 238 yuan 1. You see, 1 your baby top 4.
There is a paper in the Journal of Business Economic Research, which is about "marketing strategy, brand awareness and consumers' willingness to pay premium".
When consumers buy, they not only pay attention to the functional value of the brand, but also pay attention to the added value of the brand.
And when buying products with the same function, they are willing to pay more for the brand. Is it called "brand premium" in vernacular?
Brand Finance, an authoritative British brand value consulting company, has a data to rank the brand value of tires in 2020.
The first Michelin? 7 1.6 1 billion dollars; Bridgestone followed, with $7.024 billion, which was close.
Among the top ten, there is China brand, and the only exquisite tire ranks ninth. I wonder if you have heard of it? The brand value is $760 million, which is one tenth of the previous Big Brother.
The tire price of 65,438+0,000 is different from the brand. 65,438+0,000 yuan of high-performance tires also cost a lot of raw materials.
Like: it's the same cup of milk tea. Some shops add some water to milk tea powder, which is no different from Radix Isatidis, 5 yuan.
The other is freshly ground black tea, and real milk is made for you. 15 yuan. We can understand that, right?
The fourth largest chemical group in Germany, Lanxess Group, reported that the formula of low-performance tires is a combination of emulsion polymerized styrene-butadiene rubber and carbon black.
However, the formula used in many high-performance tires is solution polymerized styrene-butadiene rubber and white carbon black.
One is called "ESBR" and the other is called "SSBR".
In Tire Industry, we found a paper on the application of silica and solution polymerized styrene-butadiene rubber in automobile tire carcass rubber.
The combination of SSBR and silica is good, and the tear resistance and fatigue resistance of the compound are obviously better than that of ESBR with silica.
Simply put: better effect and better performance.
In terms of price, although most natural rubber is imported from Southeast Asia, it is similar. But in synthetic rubber, there is a difference.
Zhuo Chuang information has a data: 20 19 solution polymerized styrene-butadiene rubber RC2564S, and the average price is stable at per ton 12600 yuan.
The price of emulsion polymerized styrene-butadiene rubber 1502 mentioned earlier has dropped to about 10000 yuan.
Isn't there a strange number behind the eraser? Equivalent: You buy shoes from Li Ning, Adi and Nike.
It's a different brand of rubber, and it's a brand. There will be differences in performance and price, so I won't go into details.
1000 tires are expensive. Before the R&D investment is high, we said, what formula is used for tires and what rubber is used in the formula? These are not patting my head and saying that I will use them.
This is because the enterprise spent a lot of money to let a bunch of R&D personnel try this line, try that one, try this one better, and try it out bit by bit in the laboratory.
In china rubber magazine, we also found a paper entitled "20 19 Global Top 75 Tire officially released", which wrote.
In 20 18, Bridgestone ranked first in the R&D expenses of major tire companies, with 939.8 million US dollars; Michelin ranked second with $764.2 million. Interesting.
The technical content of patterns is higher.
In addition to rubber formula, there are many places for tire development. Our tires are not empty, are they? Is it regular? Just like we have to have a pattern on the sole, right?
Isn't the pattern just a few lines? What is the cost of this? Just open a mold and it will be ready.
Actually, it's like this: where is the horizontal drawing of the pattern? Or are you standing there vertically? How many stripes are drawn on a tire? Be particular.
For example, tire tread pattern can provide better grip for tires, but it will produce additional noise.
Qingdao University of Technology has a master's thesis "Study on the Influence of Tire Pattern Pitch on Noise and Its Optimization", which was mentioned above.
The noise of tire mainly comes from the pump noise produced by tread pattern. Isn't the air in the tread groove squeezed during tire rolling? Then let it out, there will be a hissing sound.
It's like: after a plastic bottle is twisted twice, the bottle cap pops open. Isn't that the sound sometimes? A truth.
It is to reduce this "bang" pump noise that tire manufacturers tend to design shallower and narrower grooves.
But in order to ensure the drainage of the tire, the width of the groove should not be too small.
At this time, it is necessary to test the technology of major tire factories. For example, the German brand UC6 tire has a silencing column in the middle of the pattern, which can reduce the inflation noise of the tire without affecting the tire drainage performance.
According to the model 2 15/50R 17 mentioned at the beginning of our video, the official price is 759 yuan.
A tire from 200 yuan is written on the product details page: Different patterns, basically no difference in performance, random delivery.
Life is like buying a tire, you never know what kind of pattern you are buying. If you make a mistake, the four tire patterns of the whole car are different.
Choosing is more important than buying expensive ones. Generally speaking, brands, raw materials, innovative technologies and so on will lead to higher prices of some tires.
But the more expensive the tires, the better. For example, a flat tire. Pirelli's flat tire price is 1 100 yuan, and it can still be driven after a flat tire.
Use it every day, okay? Is fetal noise acceptable? It is possible that in addition to tires, it must be matched with the model to reach an acceptable range.
If we rush to buy one, we may be noisy to death. So buy tires according to your own needs.
If you want to make the tires quieter, choose silent tires, which is written in Chinese as "silent tires", right? I want to be stronger. It says "sports tires".
