For freight drivers who run for a long time, flat tires have become a major safety hazard on long-distance driving. Long-term high-speed driving causes the tire to overheat and is in a state of thermal saturation. The pressure inside the tire also rises with the increase in temperature, which can easily cause a puncture. In summer, it is a tire bursting season. To effectively solve the worries of customers, Bridgestone, the world-famous tire manufacturer, continuously enriches tire durable products, and launches a new generation of upgraded products with higher belt durability.
Bridgestone R288 SUPER and M858 SUPER adopts a tread design combining three zigzag patterns and lateral grooves for Chinese road conditions in a highly durable series of load-bearing tires for good road development. Performance and excellent handling stability, thus achieving the dual effects of power steering and safety. In order to meet the different needs of users, the two tires in the segmentation function also have their own advantages. Excellent handling stability has won wide acclaim for the R288 SUPER, and the M858 SUPER has been favored for its outstanding performance in reducing transportation costs due to long wear life. In order to meet market demand, Bridgestone has expanded product specifications since July. Based on the existing five specifications, it has added 7.50R16 specifications to provide more economical choices for truck users in the light load field.
According to expert analysis, the temperature is the “culprit†that triggers a puncture in many factors that trigger a vehicle puncture. Bridgestone targets the 8.25R16 specification, which is widely used in the light load industry, and introduces the second-generation upgraded products, R288 SUPERII and M858 SUPERII, which have excellent low heat generation properties, and achieved mass production in July. Compared with a generation of products, R288 SUPERII and M858 SUPERII increase belt durability by 12% and 18%, respectively, and the crown thermal failure rate is reduced, which effectively reduces the occurrence of high-speed tire bursts. While protecting the safety of drivers, it also prolongs the service life of tires.
Road traffic not only involves the life safety of everyone, but also relates to the happy life of thousands of families. Bridgestone, with its corporate mission of “contributing to society with the highest qualityâ€, always adheres to providing “safety†and “relief†with the highest quality, and strives to become a company that is trusted and loved by people and takes pride in it. As a leader in the tire industry, Bridgestone will continue to provide Chinese consumers with more economical and safe tire products, thereby contributing to the improvement of a safe driving environment and the promotion of a harmonious and beautiful automotive society.
1. Wear-resisting steel plate is composed of two parts: low carbon steel plate and alloy wear-resisting layer. The alloy wear-resisting layer is generally 1/3~1/2 of the total thickness. When working, the matrix provides comprehensive properties such as strength, toughness and plasticity to resist external forces, and the alloy wear layer provides the wear resistance to meet the requirements of specified working conditions.
2, wear-resisting steel plate alloy wear-resisting layer and substrate is metallurgical combination. Through special equipment, the use of automatic welding process, the high hardness self-protection alloy welding wire evenly welded on the substrate, composite layer number of one layer to two layers or even multilayer, composite process due to the alloy shrinkage ratio is different, uniform transverse crack, which is the remarkable characteristics of wear-resistant steel plate.
3, the gold wear-resistant layer is mainly chromium alloy, but also add manganese, molybdenum, niobium, nickel and other alloy components, metallographic structure in the carbide fiber distribution, fiber direction and surface vertical. The microhardness of carbide can reach HV1700-2000, and the surface hardness can reach HRC58-62. Alloy carbide has strong stability at high temperature, maintain high hardness, but also has good oxidation resistance, under 500℃ completely normal use.
