At present, the number of heavy-duty vehicles only accounts for 5% of the total number of motor vehicles, but the emissions of nitrogen oxides and particulates inhaled respectively account for 74% and 85% of the total vehicle emissions. To this end, relevant experts said that the improvement of tires is the key to reducing the emissions of heavy vehicles. Bridgestone (China) Investment Co., Ltd., which manages Bridgestone's tire business in China, has announced that its two products, the high-performance, low-fuel-weight tire star Tire Radial Radial Tire, have a total of three models. Landing in the Chinese market, it fully embraces the new era of “light†assembly in the automotive industry.
As everyone knows, large-scale card passenger cars not only shoulder the efficient and safe road transportation, but also carry the important mission of urban construction, but the accompanying environmental issues are obvious to all. As a result, reducing vehicle weight, achieving fuel savings, reducing costs, and being safer and more reliable have become a benchmark for joint efforts of medium and heavy-duty automakers and component manufacturers. At present, the load-bearing shafts of over 95% of heavy-duty trucks on roads in China are equipped with twin tires. The loading and unloading process is relatively complicated, and the inner tires are difficult to maintain and bring about inconvenience to users. And from the environmental point of view, the production and use of twins have brought about certain environmental burdens to varying degrees.
It is understood that Bridgestone’s launch of the wide-radial radial tire is a combination of meridianization, flattening, and tubeless technology that uses a single tire instead of twins. Compared with twin-use tires, the wide-radial radial tires are easy to maintain and have lower tire rolling resistance and lighter weight, which can effectively reduce fuel consumption and save costs for users. Using a wide-radial radial tire also increases the distance between the inner side of the coaxial tire and improves the stability of the vehicle when the vehicle is running at high speed. At the same time, it also reduces the use of resources in the manufacturing process, thereby reducing carbon dioxide emissions and contributing to environmental protection.
At present, wide-based, high-performance tires have become the direction of tire technology. Experts said that the Tire Industry Policy, which has attracted much attention from the industry, encourages auto companies to assemble new tire products and injects strong support for the development of China's broad-based radial tire market. With the encouragement of market demand and policies, Bridgestone's introduction of a wide base tire can be a wise move.
As early as the beginning of the 21st century, Bridgestone's R&D team started with tire development and redesigned its products, aiming to build a wide-radius, low-cost, energy-efficient, high-radio radial tire product for large trucks and buses. The two products launched by Bridgestone (China) are R168 (385/65R22.5) and M748 (385) designed specifically for the mid- and long-distance loading areas, and the hanging wheels of semi-trailer vehicles with good road conditions. /65R22.5, 425/65R22.5). R168 has the characteristics of excellent durability and long life. Even distribution of ground pressure can effectively suppress the occurrence of partial wear. The M748's wide tread deep groove design allows it to have long wear life and excellent durability and wear resistance. It can be said that the listing of these two products has helped the driver to control the operating costs to a great extent. It is the best reference for many large truck drivers.
Today, the wide-radial radial tire has been successfully applied in Europe and the United States, accounting for 22% of the European truck tire replacement market, and its market share in the United States is also increasing. According to industry insiders, the two wide-base tire products launched by Bridgestone in the Chinese market will set off a “light allocation†boom in China’s heavy-duty truck market, leading the energy-saving future of China's medium and heavy-duty truck industry to a low-carbon environment. Step forward.
