The earliest period of development of all-steel radial tires in China dates back to the 1960s. However, no substantive progress was made at the time based on the gap in technology and equipment.
The real development of China's all-steel radial tires should be around the beginning of the 21st century, and it must achieve rapid development after the turn of the century. The popularity of meridianization has grown significantly, from less than 30% to about 90%, which is a quantum leap forward. .
The development of all-steel radial tires is mainly affected by two major aspects: one is external influence factors, and the other is internal product advantages. Focus on this two aspects of analysis.
External influence
The external influence factors mainly come from the external influences of the industry. Many policies and regulations are used to supervise the overall change of the industry. The main influence factors are as follows.
First, on December 28, 2000, the relevant state authorities issued a notice on “Exemption of Consumption Taxes on Tire Carriages in Tire Tax Itemsâ€. While other types of tires are still unable to escape the fate of “financially valuable productsâ€, they are forced to pay 10% of the consumption tax on tires of tire production companies while paying 17% of value-added tax.
As a result, the policy adjustment laid the foundation for the increase in the production of all-steel radial tires in the later period, thus also inhibiting the expansion of the production of tax enterprises and, to a certain extent, supervising the upgrading of the products of enterprises with conditional changes.
Second, in September 2010, the Ministry of Industry and Information Technology issued the “Tire Industry Policy†announcement. According to the industrial development plan, by 2015, the radialization rate of domestic passenger tires will reach 100%, the radialization rate of light-duty truck tires will reach 85%, and the radialization rate of heavy-duty trucks will reach 90%.
<br> <br> inherent advantages of the inherent advantages of the product means all-steel radial tire tire itself has a variety of other irreplaceable advantages for development, mainly in the following aspects.
First, the service life is longer. Since the all-steel radial tire has a belt with a greater rigidity between the tread and the carcass ply, when the tire rolls on the road, the circumferential deformation is small and the relative slip is small. Because of the large radial elasticity of the tire carcass, the ground contact area of ​​the tire is increased and the pressure is reduced. Therefore, the tread has strong wear resistance, and its mileage can be 30% more than that of ordinary tires.
The second is low rolling resistance and low fuel consumption. Because all-steel radial tires have a small number of plies, low driving temperatures, and fast heat dissipation, and because of small circumferential deformation, the rolling resistance is 15%-20% smaller than that of ordinary tires, and the sliding distance is about 25% more.
The third is large carrying capacity. Since the arrangement of the all-steel radial tire cords is in line with the main deformation direction of the tires, the strength of the cords can be fully and effectively used, and therefore the load capacity of the tires is more than 10% higher than that of ordinary diagonal tires.
Fourth, shock absorption performance is good. Due to the radial elasticity of the all-steel radial carcass, the radial (vertical to the direction of the ground) deformation is large, and the impact of the uneven road surface can be mitigated.
Overcapacity show <br> <br> In this way, all-steel radial tire ushered in the development of "opportune" situation. However, as the industry progresses unrestrainedly and expands production capacity without restraint, the problems also arise.
"This expansion of production capacity, this kind of growth, really good?" Since 2010, China's tire industry has issued such a question.
In fact, the development of the Chinese tire industry has indeed encountered some problems. This is the industry’s most feared and most hurt “overcapacityâ€. It's not the business that is feeling this pressure quietly, and it's more that this kind of excess crisis has begun to radiate the industry, allowing companies to be selected and eliminated in the industry's survival.
In the face of such a supply-demand pattern, tire manufacturers began to falter, market sales began to fear, and tire profits began to shrink.
In particular, in 2014, the Shandong Provincial Government issued a notice to limit new and newly-increased production capacity, which imposed certain mandatory pressure on local tire production capacity. This kind of coercion does indeed deter new businesses in the industry, making it no longer easy to grow in the past two years.
Cessation or suspension of a steel tire project into the rest of <br> <br> can be seen from the statistics, Shandong tire companies in the new capacity still has an absolute advantage, but the process is relatively slow, and even some delay Not started.
It is understood that some of these companies have failed to approve the new projects, partly because of the lack of start-up funds and their inability to start, and partly because the current market is under so much pressure that companies are temporarily taking a wait-and-see attitude and suspending the start-up process. .
The transformation between ideals and reality is always a result of having a dream and becoming beautiful, but also becomes boned by reality. Judging from the current market operation situation, it is difficult for new tire companies to enter the market and the risk assumed later is greater.
From the current point of view, the Chaoyang phase of the all-steel radial tires has passed away in the past, leaving more new regulation of the industry's reintegration. This is not to say that the domestic tire industry has entered a period of sluggish decline, and more is the industry's entering into the rest period.
This kind of stoppage is focused more on sorting out the pros and cons of the industry, abandoning the inefficient production capacity, and at the same time, it also gives more opportunities for the development of the enterprise.
The growth rate of China's all-steel radial tires has entered a rational and balanced state. The reorganization of the industry and the re-matching of demand will be an unshakable development task in the next five years.
At this time, no one can make a certain conclusion for the tire industry, and more is to give time for self-recognition, self-reform, and self-transformation, so as not to make the main force of the industry lose the correct development direction after the big waves break through the sand.
